Maintenance & Cleaning
Maintenance
Cobia advises owners that maintenance and repairs should be performed at an
authorized Cobia Dealer. The following information is general in nature and should not
be considered a repair manual or guidelines set forth by Maverick Boat Group.
Cleaning
Each Cobia boat is constructed using the finest materials and components available.
However, no material is immune to the ravages of the saltwater environment. After each
use, your boat should be thoroughly washed using fresh water. To avoid water spots, dry
your vessel using a soft cloth. A fiberglass wax may be used to preserve the luster of the
hull.
Thorough and routine cleanings of your stainless fittings are required to maintain their
appearance. After each use of your boat, clean stainless fittings using fresh water and a
mild soap. Dry fittings completely. A wax or polish may be applied after cleaning. Any
rust must be removed as soon as possible to prevent irreversible damage to your vessel
and/or its components. A light coat of lubricant on metal railing, screws and electrical
connections will help prevent electrolysis. The same holds true for your trailer. Refer to
page 47 for upholstery care and cleaning instructions.

Engine Break-In Period
Engine Break-In Period
New engines require a period of break-in to allow the surfaces of the moving parts to
mate evenly. Different engines require different break-in periods and methods. For
instructions on break-in methods, refer to your Yamaha Engine Owner’s Manual for the
correct break-in procedures and times for your model engines.
Engine Stop Switch
If activated, the spring-loaded engine stop switch
will automatically shut down the engine during
emergency situations to prevent uncontrolled or
unattended operation. Certain emergency conditions
(e.g., turbulent water, wakes, unanticipated
movement) may impair a person’s ability to operate
the craft safely. The switch, located on the helm,
must have the safety lanyard attached at its base.
This activates the protective shutdown circuitry.
Securely attach the other end of the lanyard to the operator of the boat. If the operator
moves, falls or is at an unsafe distance from the steering wheel, tension on the lanyard
will pull it from the switch. When the lanyard is removed, the engine stop switch is
released and automatic engine shutdown occurs.
Engine Stop Switch
DANGER:
An engine stop switch system that is not used or does not function
properly can cause death or serious injury. DO NOT operate the boat if
the engine stop switch system does not function properly. Go to a
Cobia Dealer to have this resolved immediately.
The lanyard should be securely attached to the boat operator at all times that
the engine is on.

Helm & Command Link Gauges
Switch Panel & Helm
At the helm of your Cobia, you have a
main switch panel, which is located above
the steering wheel. This panel controls
your lights, horn, accessories, livewell,
and your bilge. When a switch is in the
“on” position, its tip is illuminated. This alerts you that the associated accessory should
be functioning and also reminds you to turn it off during boat shutdown. When the
“NAV” light switch is in the “on” position, the labels for the switches will be illuminated.
To the right of the steering wheel you have your two trim tab switches. The boat also
comes standard with a compass mounted on top of the console.
When the indicators above the bilge switches are illuminated in red that means the bilge
pump is running from its float switch being activated. It is not uncommon for the float
switches to be activated for a few seconds for a couple periods over the course of a full
day on the water. However, if the bilge indicators stay on for a prolonged period or come
on numerous times, this is likely evidence of a leak and the bilge should be checked
immediately for water intrusion. Any leaking should be addressed right away. For more
information on the bilges, bilge pumps and bilge switches, refer to page 11.
Command Link Gauges
Yamaha’s new 6YC Command Link gauge
comes standard on your new Cobia. This
gauge allows access to more information and
is user-selectable so you can choose the
functions displayed. Speed data can be
displayed from a pitot tube, Triducer, or
NMEA protocol GPS unit. To learn the gauge’s
full functionality, refer to your Yamaha engine
owner’s manual located in the Cobia Duffel
Bag.

Cobia Duffel Bag
Along with your boat, you received a Duffel Bag with your new Cobia. Inside the Duffel
Bag are the following items:
oLarge Livewell Standpipe
oShort Livewell Standpipe
o1.5” Livewell Pacifier Plug
o2 ignition Keys and Emergency Kill Cord /Engine Stop Lanyard
oEngine Start Cord
oVarious Accessories Manuals
Fuel-Water Separator & Drain
Fuel-Water Separator
Two Yamaha Fuel-Water Separators are installed on the portside of the transom pass
through. The new, improved 10-micron filter provides superior filtration ahead of the
engine's on-board filters and injectors. Large filtering and water capture areas maximize
filtration while maintaining adequate flow rate for larger engines. The micron filter and
head are mounted inside an access panel located aft of the port transom gate. The fuel
system primer bulb is located next to the filter. The fuel separators can be checked by
removing them from the mounting bracket and dumping it into an approved waste
collection device. If there appears to be an excessive amount of water, the filter
component should be replaced. See your authorized Cobia Dealer for replacement parts.
Maintenance Note: Yamaha recommends replacing the 10-
micron fuel filter on new boats after the first 10 hours or 1 month of
operation and every 50 hours or every 6 months thereafter. In
areas of high humidity where water in fuel supplies is a problem or
extensive engine operation occurs, more frequent replacement
may be necessary.

Garboard Drain Plug
The garboard drain plug is the small metal plug located at the
lowest point on the hull, at the bottom of the transom right above
the keel. The drain has been designed so that it can be loosened
by hand while the hull is out of the water for draining. This
allows the plug to stay in contact with the surrounding frame so
you’ll never misplace or lose it. You can completely remove the
insert by pulling back and continue turning in a counter-
clockwise motion. It is manufactured with a rubber seal in place
to ensure your bilge is watertight. Always make sure before putting the boat in the water
that this plug is hand tightened firmly. Excess water in the bilge may be an indication of
a problem with this plug or the automatic bilge pump. (Refer to Water Drain System
diagram, page 43.)
Bilge
Bilge Access
Accessing the bilge on your new 301 is made easy. First, locate the controls on the
electronic lift assist, labeled “Hatch”, mounted on the starboard side of the tackle station
directly across from the gunwale. Next, press and hold the top button on the controls.
This will cause the rear access to lift revealing the bilge access. To lower the hatch
simply press and hold the bottom button on the control panel until the aft section is
fully closed. Remember that the electronic lift assist operates using the house battery
system.
In the event that the boat does not have power to electronically lift the hatch, the
electronic lift can be disengaged by lowering the bench seat and using the access
opening shown below to remove the pin from the electronic ram. Keep in mind that at
this point the hatch will no longer be supported in the up position and will require being
held up to maintain access to the bilge. Once the work in the bilge is finished and power
is restored to the hatch lift, it is important to attach the ram to the hatch with the pin
once again to secure the door in the closed position. To access the forward bilge pump,
disassemble the drawers underneath the bathroom sink.

Bilge
The bilge of your Cobia should always be checked before and after a launch. While
checking the bilge, note that a small amount of water in the bilge is normal. However, a
large amount of water or any signs of fuel or oil requires immediate attention. If such a
situation exists, the boat should be taken to a certified marine technician
immediately. Never pump fuel or oil overboard while your boat is in the
water.
Large quantities of water in the bilge may be an indication of a leak or that the bilge
pump and/or automatic float switch is not functioning properly due to a jam, clog or
electrical issue. The automatic float switch is wired to the 24-hour side of the battery
switch through the “BILGE” breaker on the battery switch panel. When functioning
properly, the float switch activates the bilge pump to pump water overboard once water
in the bilge reaches a level that submerges the switch.
If the bilge pump does not come on when the float switch is submerged, attempt to
manually turn it on through your switch panel. If the bilge pump comes on and
evacuates the water, it is clear that the float switch is not functioning properly. If the
bilge pump does not come on via the switch panel, check the breaker on the battery
switch panel to see if a breaker has been tripped. If the breaker has been tripped, reset it
and turn the switch on again, listening for the bilge pump to turn on.
If the bilge pump fails to turn on, turn the battery switch to the OFF position, then
unhook the bilge pump from its cradle by pressing the locking tab and twist motor
housing counter-clockwise. You will feel the pump release from the cradle. The entire
bilge pump and wiring should release from the cradle. After removing the pump, check

the underside and impeller areas for miscellaneous items that might clog the pump. If
any obstructions are present remove the debris and set the pump back into the cradle.
Once set back in the cradle, press the pump down on the base then twist until the lock
button snaps it into place. Once this is completed you can try to turn the pump on again.
If the bilge pump still does not turn on, it likely needs to be replaced. It is not
recommended to use your boat if the bilge pump and/or float switch are not functioning
properly.
Systems
Ball Valves
Ball valves can be used to serve several purposes. They allow
seawater to enter the boat, in the case of livewells, and they also
act as a safeguard to stop water from entering. To tell
which position a ball valve is in, open or closed, look at the
valve and determine the direction of flow. When the ball
valve handle is in the same position as the direction of
flow, the valve is in the “OPEN” position. When the ball
valve handle appears to cross the direction of flow, the
valve is in the “CLOSED” position. The ball valves can be
accessed in the bilge compartment behind the aft seating.
301 Deckdrain System
The deckdrain system is equipped with 1 1/2” thru hull fittings through the aft port and
starboard hull sides. These fittings have to be installed lower than the drains in the
cockpit floor so that gravity will allow the cockpit to drain free of water. This puts these
fittings very close to the water line of the hull. These drains are rigged with ball valves
that can be opened and closed to control the flow of water. In the open position, these
ball valves will allow water to flow freely from the cockpit, thus making the boat “self-
bailing”. When closed, no water will be allowed to travel to or from the cockpit.

(772)-465-0631 •cobiaboats.com
301 Livewell Pump Assembly
The livewell pump assembly is composed of a scoop strainer
mounted to the bottom of the hull, a thru hull fitting, ball valve
assembly, and the pump. As you can see, the ball valve assembly is
in the “OPEN” position. This is the correct position for the
operation of the livewell.
Console/Head Access
Located at the top on the inside of the console/head access door is a locking gas shock
that aides in opening the door and keeping the door open once the shock is fully
extended. With the door fully opened, it can only be closed by releasing the pressure of
the metal sleeve on the door side against the shock
that is mounted to the console. To do this, open the
door to its fullest open position, thereby allowing
the door slide sleeve to be moved so that it will slide
overtop of the gas shock as the door closes. Failure
to release this locking mechanism while attempting
to close the door will lead to the gas shock failing, or
damage to the mounting brackets.
DC Main Breaker Panel
The DC main breaker panel is located to the left of the mirror and contains
the breakers for the accessories on the helm switch panel. If an accessory is
not working it may because its breaker has been popped. Simply find the
rubber button on the breaker panel for the associated accessory and press it
in. You should feel an internal button move in and then catch. This will reset
the breaker and close the circuit. If the accessory still is not working or the
breaker pops again, another issue is present.
The backside of the switch panel and the electronics can be reached inside
the door with the mirror. The fuse box on the back of the door contains the
fuses for the helm electronics such as the GPS units and VHF.

Electric Head Operation
To operate the head, first, make sure that the intake/fill valve located on the inside of
the bottom of the hull accessed through the hatch to the left side of the toilet (see
Sanitation System diagram, page 38). The valve is open when its handle is pointing
straight up. This will allow water to enter the head upon flushing.
Once you’ve finished using the head, press the flush button labeled “Elec Head” on the
switch panel. This will push the contents of the head into the holding tank. Note that the
toilet contents will always go into the holding tank first, no matter if planning on
pumping out or using the macerator.
To evacuate the holding tank via a
marina pump out, make sure that
the handle for the Y-valve (located
in the access hatch to the right of
the toilet) is in the correct position.
This will allow the tank contents to
be sucked out of the tank via the
waste deck fitting on the deck. The
discharge for the deck fitting will
always be the topmost outlet on the
Y-valve. The handle is in the
correct position if the arrow for the
top outlet IS NOT covered by the
wide end of the handle.
Note: The visible arrows on the Y-valve always show the direction of
the flow. In other words, the wide end of the handle always covers the
arrow for the outlet where the flow is NOT going to go. If the flow is
pointing downwards, the waste is being directed through the bottom
of the hull and overboard. If the flow is pointing up, the waste is being
directed upward to the deck and the pump out fitting.
Intake/Fill Valve in the “OPEN” Position

16
Maverick Boat Group
3207 Industrial 29th St. • Fort Pierce, Florida 34946
(772)-465-0631 •cobiaboats.com
This is the position the handle should be kept in at all times to prevent the possibility of
mistakenly discharging waste overboard in waters illegally. (Within 3 miles of shore and
where otherwise designated.) If desired, the handle can be locked in this position by
inserting a padlock through the hole on the handle and through the housing on the Y-
valve.
To evacuate the tank overboard using the macerator, open the valve on the waste
discharge thru hull located next to the head intake valve/thru hull. The Y-valve handle
should then be turned so that the wide portion of the handle covers the silver arrow for
the pump-out outlet (the top outlet.) The visible arrows should now be showing the flow
to be going downward. Next, press down the macerator switch on the panel. This will
push the contents in the holding tank out the bottom of the boat through the waste
discharge thru hull. Once the process is complete it is advisable to close the discharge
valve and put the Y-valve handle back into the pump-out position. (The wide portion of
the handle covering the down arrow.)
The Jabsco Y-Valve is designed to provide flexibility of onboard waste management by
diverting waste either to the dockside pump-out fitting or directly overboard where legal
to do so. Check local and federal regulations to determine where direct overboard
discharge of untreated waste is permitted.

Ladder & Props
Stainless Boarding Ladder
This Cobia model comes standard with a telescoping stainless-steel boarding ladder
integrated into the starboard aft platform area. This provides a stepping area while the
ladder is in the up position. Once the ladder is down and in the extended position, close
the lid cover for safe and secure entry and exit via the ladder. When washing off your
boat at the end of the day make sure to extend the ladder and wash it off as well, making
sure to dry it completely before stowing. Leaving saltwater in the telescoping tubes may
lead to corrosion and affect the useful life of your ladder.
Props
Prop selection on your Cobia is determined by your
local Cobia Dealer, but all props are based on
recommendations from Cobia Boat Company and
Yamaha Marine in order to give your boat maximum
overall performance. The needs of your prop will
determine the prop design and size that best fits your
performance requirements. Always inspect the
engine and prop prior to launching your boat with
DANGER:
No passenger should attempt to enter or exit the boat by
the ladder or by any other means while the engine is on.

the engine off. Key prop issues include tangled fishing line or other types of debris,
cracked blades or fluid leaking out of the seal. Look for fishing line tangled around the
prop or lower unit seal. Consult your Yamaha Owner’s Manual to address these
issues.
Fuel System
Fuel System
This Cobia comes equipped with a 267-gallon fuel cell stationed below the leaning post
between the stringer system. There are two fuel fill receptacles, one on the port gunwale
and one on the starboard gunwale. The primer bulbs are located by the transom gate
inside an access hatch. Every fuel tank is pressure tested at the factory before and after
installation. Should you experience any fuel related problems or suspect problems with
the fuel system, immediately take your boat to a Cobia Dealer. See Fuel System Diagram
on page 39.
DANGER:
Do not smoke while filling the tank. Be sure to turn off the engines
and all electrical equipment when fueling the boat to prevent
accidental discharges of static electricity. Use only the
recommended gasoline (see Yamaha Owner’s Manual). Do not
use fuels with alcohol or alcohol related derivatives that can
cause marine fuel system hoses to deteriorate.

Self-Bailing Cockpit & Livewell
Self-Bailing Cockpit
The cockpit is designed to be self-bailing, meaning that all the water that comes into the
cockpit will be directly drained overboard. This keeps the boat from acquiring standing
water and allows the boat to drain at all times, including while the boat is docked.
Water drains out of the cockpit through two aft cockpit drains located at the far aft
cockpit floor on both the port and starboard sides. Each side drains overboard through
the side of the hull independently. None of this water is drained into the bilge. The ball
vales are located inside the hull sides and can be accessed through the bilge hatch. Refer
to page 13 for operation of the ball valve associated with this system.
The bilge is designed to drain any water entering the inside of the hull. All hoses are
sealed and double clamped during construction. Continuous or periodic running of the
automatic bilge pump may be an indication of a hose leak or break in a seal and should
be investigated by a Cobia Dealer immediately. Refer to page 11 for further information
regarding bilge pump operation and maintenance. A diagram of the Water Drain system
can be found on page 43.
Livewell System
The livewell system is designed to keep your
baitfish alive and strong for as long as possible.
This livewell provides a cool, clean, and
oxygenated environment that allows you to keep
your baitfish alive for long periods of time. To
efficiently operate your livewell, the following
steps should be taken:
1. Open livewell hatch.
2. Install stand-up pipe snugly.
3. Ensure livewell pump ball valve is in open position.
4. Turn on livewell switch.
