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 40 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 to the left of
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.
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
A Yamaha Fuel-Water Separator, or two for twin engines, is
installed behind the aft seat assembly. Simply lift up the seat
and you will be able to easily access the Fuel-Water separator.
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 fuel separator can be checked by removing it 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.
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 the Water Drain System diagram on page 37.
Fuel-Water Separator
Drain Plug
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.

Bilge
Bilge Access
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.

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 hot side of the battery switch through the
“BILGE” fuse at 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 panel inside the
console 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.
240 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.
240 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.

Cockpit Courtesy Lights
Cockpit Courtesy Lights
The cockpit comes equipped with three LED courtesy lights installed at the factory.
These lights illuminate the entire cockpit and are controlled by the switch panel. The
switch labeled “COCKPIT LTS” controls the courtesy lights. The courtesy lights are
mounted beneath the port and starboard gunwales as well as at the bow, aft of the
anchor locker.
Battery Switch Panel
The battery switch panel is located on the port side of the helm seat
tackle station. The top switch is for your engine(s) battery(s). The
bottom switch is for your house battery which powers all of your
electronics and accessories. Both switches must be turned to the
“ON” position in order to fully operate your boat.
If your engine(s) battery(s) is too low to crank your engine(s), you
can turn the engine switch another quarter turn to the “emergency
parallel” setting as denoted by the yellow area at the 5 o’clock
position on the label. This will allow the house and engine batteries to
combine and provide enough power to crank your engine(s). Once
the engine is cranked and on, turn the switch back to the “ON”
position so that the engine begins to charge its battery back up again.
Leaving the switch in the “emergency parallel” may also risk electrical
damage to your accessories and engine. When you’re finished using your boat, turn both
switches to the “off” position to prevent any current drain while the boat is not being
used.

Ladder & Props
Stainless Boarding Ladder
This Cobia model comes standard with a telescoping stainless-steel boarding ladder
integrated into the port 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 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.
DANGER:
No passenger should attempt to enter or exit the boat by
the ladder or by any other means while the engine is on.

Fuel System
Fuel System
This Cobia comes equipped with a 125-gallon fuel cell
stationed below the leaning post between the stringer
system. The fuel fill receptacle is on the port gunwale.
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, page 36.
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. Refer to
page 11 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
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.

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
10 for further information regarding bilge pump operation and maintenance.
Livewell System
The livewell system is designed to keep your
baitfish alive and strong for as long as
possible. This 28-gallon 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.
The livewell operates by pumping fresh seawater from the pump through an aerator
head into the livewell. Drainage is achieved through the grate on the top of the
standpipe, which, when unobstructed, will limit the water level to the standpipe’s
highest point. A shorter standpipe can be used to keep less water in the well. This
constant drainage keeps up water flow and allows for the removal of ammonia from the
livewell, therefore extending the life of your baitfish. To drain the livewell, switch off the
pump, close pump ball valve, and remove standpipe.

Rod Storage & Fish
Lockers
Rod Storage
The 240 Center Console model comes
standard with under gunwale rod racks on
both the port and starboard sides. These give
you space to safely store an additional 6 rods
for your fishing needs.
Port and Starboard Fish
Lockers
The 240 CC has two 33-gallon fish
lockers located port and starboard of
the cockpit. These lockers are
insulated and drain overboard
through independent thru hulls on
each side of the hull just below the
boxes. These lockers can also double
as storage for various other items.
Macerator Access & Operation
Macerator Switches
The switches for each fish box macerator are located on the switch panel left of the
steering helm. These can be operated independently of each other and the switches are
labeled.

Anchor Locker
Anchor Locker/Rode Storage
The anchor locker is located at the bow of the boat and is accessible through the anchor
locker door or hatch (photo below). There is an eye mounted to the bow eye to secure
your anchor rode or chain to. After setting your anchor, the excess rode can remain
stored in the locker. The notch supplied in the door allows you to securely close the
locker by aligning your rode through the notch.
Trim Tabs
Trim Tabs
Bennett trim tabs are standard on your new Cobia.
Integrated electric trim tabs can enhance the
performance of your boat. The tabs are electric and
therefore do not require a trim tab pump. By not having
a pump there is no possibility of fluid leaks from a
pump.
Trim tabs allow for maximum boat performance and are
great for balancing weight in the boat. They also allow
the boat operator to lift or lower the hull to
accommodate for different running situations.
For the operation of trim tabs note that the port trim tab switch will affect the port side
of the boat, and the starboard switch will affect the starboard side. To lower a particular
side, press the top of the corresponding switch down. Pressing the top of both switches
down will lower the bow evenly. To raise the bow, press the bottom of the
corresponding switch.

Standard Features
Standard Fresh Water Shower
The 9.5 gallon fresh water tank on your new Cobia can be filled at the
cap labeled “FRESH WATER”, on the back starboard corner near the
transom. The hose nozzle is on the port aft bulkhead. To pressurize
the system, flip the switch labeled “FRESH WATER” on the switch
panel at the helm. You can leave this switch in the ON position while
the boat is in use. The pump has an internal pressure switch that
allows the pump to turn on and off as needed.
In the colder months of the year, it’s advisable to drain the freshwater
system and winterize by adding a non-toxic antifreeze to the system. Run the antifreeze
through the system by opening up the spray in the shower nozzle until antifreeze is
delivered through the nozzle.
Optional Features
Optional Bow Cushion Set
The 240 CC comes with the
option of a six-piece bow
cushion set. These cushion
bottoms are removable and
are held in place by several
sets of stainless-steel snaps.
To remove the cushions,
simply pull the snap strap
away from the embedded
snap and remove the cushion.
When left outside or exposed
to the elements for a
prolonged period of time, it is
recommended to take off the
seat cushions and store them
in a dry place. Refer to page 40 for cushion care instructions.
