Dear 35z Owner
Congratulations on becoming an owner of an MJM 35z. We’re dedicated to making it the
world’s best in class. As you read this guide and share cruising adventures, we hope you’ll
discover our mission has been accomplished.
MJMs are built of the highest quality materials, a composite of epoxy, Eglass and Corecell.
That contributes to MJMs being most fuel-efficient yachts of their type by a wide margin. The
same is true in the selecting of equipment suppliers and cabinetmakers. 35z is built to
structural scantlings of Category A and certified ISO Category B Offshore, the highest rating
for seaworthiness achieved by a boat under 40 feet. 35z leads the outboard market with
unusually complete standard specifications and amenities. The boats are safe, reliable, easy
to handle by one person, and high performers. Last but not least, and our number 1 design
mandate, they turn heads entering harbor.
In addition to this Owners Guide, and primary in terms of authority, are two large binders with
equipment supplier owner manuals and warranties. These documents contain an enormous
amount of important information. Please keep them accessible for reference when you have
an issue or question not covered in sufficient detail by this guide. You can download most
from supplier websites onto an iPad or install them on the Raymarine display.
This guide reflects our experience from building over 250 MJMs. I personally have spent
more than 6000 hours cruising on MJM yachts so want to impart some advice and
background information along with the “how to do it.” See comments in the blue sidebars.
As you enjoy your new boat, remember that much of the equipment contains computer
chips that can sometime have glitches, which are often corrected with a re-boot. With proper
safety precautions and good weather planning, you will spend many enjoyable hours on your
new vessel.

QUICK START GUIDE
Here’s a reminder checklist for an experienced captain, familiar with operation of twin Mercury Verado
outboards equipped with Joystick Piloting and information in this guide and accompanying binders.
Check Systems
CHECK to see that raw water strainers of the GENERATOR and combined SEAKEEPER/AIR
CONDITIONING, located under aft cockpit seat are not clogged.
Change AC Power Source - Shore Power to Inverter
Turn OFF the SHORE POWER breaker at the 120V AC panel. Then:
1. If planning to use the GENERATOR to power the AIR CONDITIONER underway, start the GENERATOR.
2. Otherwise turn ON the INVERTER on the AC Panel as well as on the PHOENIX CONTROL panel to
sustain power to 120V AC circuits such as the ICE MAKER and AC OUTLETS on the AC Panel.
Turn OFF Dock Pedestal breaker first, then disconnect/stow shore power and TV cords
Activate 12 Volt Equipment
With HOUSE BATTERY switch ON, check for at least 12.2V on the electrical panel. Turn ON
ELECTRONICS, TRIM TABS, WIPERS, HORN, FW PUMP, GYRO and other breakers for equipment used
underway… such as HEAD, NAVIGATION LIGHTS and SEARCHLIGHT if at night.
Turn ON two red ENGINE BATTERY rocker switches at the top of the 120V AC panel.
Insert TPS key fob (Theft Prevention System) into its slot above the electrical panels.
Insert and turn ON ENGINE KEYS high up under companionway bulkhead (where they can’t be
accidentally broken or switched off). Listen for acknowledging beep and look for Green “Systems OK”
Light on Vesselview. (Key Code 35z #1 is “996”)
SELECT “Engine Page” on VesselView and check engine battery voltage in top center.
If batteries are low, don’t leave the dock until you diagnose and correct the problem.
LOWER engines using rocker switch on port control handle, confirmed by trim bars in lower center
on VesselView.
Ensure people, equipment, lines and hoses are clear and not in the water before starting.
Start Your Engines
Momentarily TOUCH engine start buttons to starboard of wheel. Don’t hold them in. It’s automatic.
TAP JOYSTICK lightly in any direction to insure it is functioning. The rim lights up GREEN.
Cast Off Confirm that no one is on the foredeck or in the water.
If everything is in order, cast off dock lines. When maneuvering with the JOYSTICK, minimize going
back to center to avoid shifting of outboard gears. If moving sideways to clear a float: You can move
the bow to catch up with the stern by twisting the knob at the same time while held sideways…
likewise with moving the boat slightly forward or aft by leaning the joystick forward or aft while still
leaning the joystick in the sideways direction desired.
Move the SHIFT LEVER forward out of neutral normal operation to automatically disengage the
JOYSTICK. The JOYSTICK is automatically ready for use (Green Lighted Rim) when SHIFT is in
neutral.

1INTRODUCTION
1.1 PURPOSE AND LIMITATIONS
This purpose of this Owners Guide and the equipment suppliers’ manuals in
the accompanying binders is to provide you with an overview of the yacht’s
equipment, operation, systems and maintenance. The people at MJM and
Boston BoatWorks have taken pains to edit this guide for accuracy in good
faith. Most of these topical require further study and learning by the captain of a
vessel who assumes extensive responsibilities for safe operation of the vessel
and for safety of the crew.
This summary guide of yacht equipment and operation will never be complete
or accurate in all respects. And, since we frequently make improvements, we
assume no responsibility for missing information or errors contained herein. This
document doesn’t replace common sense nor qualify the reader in safety
practices, boat handling or navigational skills. Mastering these systems and the
skills of seamanship is each owner’s/captain’s responsibility. If this is your first
yacht, or if you’re changing from a different type of yacht, please get instruction
and experience before assuming command. Your dealer, yacht club, marina or
the US Power Squadron https://www.usps.org are all good resources that can
recommend licensed captains, schools or other instructional entities.
Although this guide and the accompanying binders describe systems on the
boat, they don’t qualify you to work on them. When they need attention, please
use qualified and certified trades personnel. If you question the information or
are unsure about an action, check with the equipment supplier, a qualified
person or us.
The Appendix includes other useful information. And there’s a chapter on the
people who create MJM yachts you can contact if you need help. Study these
resources to understand how to operate your yacht safely.
The operation of a powerboat can be dangerous. Pay careful
attention to safety notices in this guide and in the manuals in the binders.
Keep this guide in a secure place on the boat. If you sell the yacht, please give
this copy to the new owner.
1.2 STANDARD SPECIFICATIONS
You may download the latest version of this guide and the standard
specifications for a MJM35z from http://www.mjmyachts.com/35z to install on
your computer, an iPad or navigational display.
1.3 CONVENTIONS
When we reference a specific device or item of equipment on the boat, it will
be in all caps, such as HOUSE BATTERY.
As we describe each device we often use the following order.
1. BREAKER PANEL settings
2. Function, what it does
3. Directions for use
4. Advice or comments in a sidebar
5. The URL for the manual if available
This guide is published in accordance

2SAFETY and some USCG REQUIREMENTS
2.1 BINDER MANUALS
The equipment suppliers’ manuals in the accompanying binders have many
safety notices that relate to their products, their operation and maintenance and
their use in the boat. Ensure that you understand this essential information
before you operate the boat. Spend time reviewing the safety procedures, how
safety equipment works and where It’s stowed. Instruct guests in safety
procedures.
2.2 STANDARD EQUIPMENT
VHF Radio BREAKER PANEL settings: ELECTRONICS breaker on. The VHF RADIO
may be used for receiving weather broadcasts, communicating with harbors,
locks (ch13), bridges (ch 9), marinas, the U.S. Coast Guard (USCG), rescue
services boats and other boats. The USCG monitors channel 16. If you normally
have your radio tuned to channel 16 you can listen for emergency calls from
nearby boats or be able to make an emergency call quickly. Don’t use Channel
16 for a private conversation.
MMSI Number The radio has Digital Selective Calling (DSC). It’s arguably the
most important piece of safety equipment on the boat. There’s a one-button
emergency transmit button that sends a Maritime Mobile Service Identity (MMSI)
number to the USCG. The signal identifies the boat. It’s interfaced with GPS so
your position will be sent with the emergency message. The Automatic
Identification System (AIS) will report your MMSI number to other vessels and
you will see their MMSI number.If you sell your boat, log onto your account to
cancel the MMSI number, so the new owner can register, acquiring a new MMSI.
In addition to the safety function, an MMSI number is like a phone number. You
can make a call to another DSC-equipped vessel if you know its MMSI number.
Only the vessel being called will receive the hail.
BoatUS http://www.boatus.com/MMSI/ is authorized by the Federal
Communications Commission and the USCG to assign MMSI numbers. The
Installation and Operation Instructions for the VHF RADIO included in the binder
explains how to install the MMSI number in your radio. It also explains how to
use the VHF RADIO. It may be downloaded at:
https://raymarine.app.box.com/s/grwg60669c5sozf6iolq/1/2757682985
The Horn BREAKER PANEL settings: HORN breaker on. The USCG requires a
“Sound Producing Device” for signals under many circumstances. The HORN is
operated from a switch on the CONSOLE SWITCH PANEL at the helm. The
adjacent UNDERWAY HORN/ANCHOR switch has programmed signals. (See
page 13.)
Electronics fail. It’s wise to have a portable VHF radio, GPS receiver,
SEARCHLIGHT and HORN that are battery operated and hand held.
Fire ExtinguishersSee EMERGENCY DIAGRAM page 5for Fire Extinguisher
locations when the boat is delivered.
Carbon Monoxide Detector See EMERGENCY DIAGRAM page 5.
To send a distress call (without
specifying its nature) press and hold the
red distress key for 3 seconds. See
Ray218E/Ray55E Installation and
Operation Instructions.

Companionway Hatch Board or Closure A companionway board with the label
“DON’T REMOVE WHILE UNDERWAY” is provided to comply with ISO requirements
for cockpit draining and to prevent large waves from crashing down into the
cockpit, running forward and entering the interior of the boat if the
companionway door is not securely closed.
2.3 COMMISSIONING PACKAGE SAFETY ITEMS
The Commissioning Package Option, if purchased with your boat, will have:
•A copy of the U.S. Department of Homeland Security United States Coast
Guard Navigation Rules to be on board. It also may be downloaded at:
http://www.navcen.uscg.gov/pdf/navrules/navrules.pdf
•A First Aid Kit
•Twelve wearable USCG approved personal flotation devices (life-jackets)
and one type IV throwable PFD
•A 12-Gauge Flare Kit
•A Hand-held Bilge Pump
•A Hand-held LED Flashlight
•Paper Charts
2.4 USCG REQUIRED EQUIPMENT
A Boater’s Guide to the Federal Requirements for Recreational Boats, published
by the USCG, lists required safety items. The Guide may be downloaded at:
http://www.uscgboating.org/images/420.PDF. Check state regulations where
you cruise for other requirements.
2.5 ADDITIONAL SAFETY EQUIPMENT
There are many other items of safety equipment to consider such as:
EPIRB (Emergency Position Indicating Radio Beacon) alerts search and rescue
services by transmitting a coded message and is detectable by satellite
anywhere in the world. Although the USCG doesn’t require them, EPIRBs are
essential offshore and desirable anywhere.
Inflatable Life Raft isn’t required but prudent. Rafts come in compact sizes that
can be stored in a cockpit locker. A dinghy isn’t a substitute for a life raft.
Heaving Line is handy to have for emergency or to simply trail behind the boat (if
the engines are off) attached to one of the stern cleats when people are
swimming. Polypropylene is good because it floats.
A Storm Anchor is useful as a back up and for situations when two anchors are
prudent or necessary.
2.6 SOME ADDITIONAL USCG REQUIREMENTS
In addition to the above safety equipment, the USCG requires:
Ships Registration and Documentation Carry the Vessel Registration, either the
state-issued Certificate of Number or Vessel Documentation if federally
documented with the USCG. It’s wise to have your insurance as well.
Pollution Regulation Plaques You are required to post three visible placards in
the boat that stipulate that waste must be managed; that oil discharge is
prohibited and deposit of any refuse matter of any kind into the waters of the US
is prohibited. West Marine has such plastic placards with adhesive backs that
are available at little or no cost.
Better to just secure the companionway
slider and lid. It’s quieter, prevents
someone from being pitched below and
provides a Chart Kit navigation surface.
