CHAPTER 1 1.1 OPERATION GENERAL This manual has been compiled to help you operate your yacht with safety and pleasure. It contains details of the yacht; the equipment supplied or fitted, its systems, and information on its operation and maintenance. Please read it carefully, and familiarize yourself with the yacht before using it.
CHAPTER 1 OPERATION It is prudent to check (or have checked) your compass alignment once the boat is in your primary area of operation. See the Ritchie instructions for compensation. Check that all equipment is functioning, even if you intend not to use it. Radar functioning and properly aligned (Double-check when underway) See manual to adjust, tune and operate.
CHAPTER 2 2.1 SAFETY EQUIPMENT GENERAL Spend time reviewing where your safety equipment is and how it functions BEFORE you need it. Remember, the best way to protect yourself and others from accidents is to eliminate potential causes of accidents before they occur. Good seamanship and common sense go a long way in this endeavor. [See Figure 14.1] Here is a safety checklist derived in part from the USCG Vessel Check List.
CHAPTER 2 SAFETY EQUIPMENT First Aid Kit Not a place to scrimp. It is advisable to carry a good, comprehensive, and well-organized (by injury) marine first-aid kit with manual. We recommend that it be stored in the head and that everyone onboard be informed of its location. (Remember, you may be the one in need of it!) 2.2 ENGINE Fuel shut-off valves are located on top of the fuel tanks and are accessible via spin-off deck plates mounted by the cockpit steps [see fuel system section].
CHAPTER 3 3.1 PROPULSION SYSTEM GENERAL The 34z is propelled by a diesel engine turning (via a transmission) a standard, four-blade propeller. The single-lever control acts as a combination throttle and gear selector. Care should be taken when shifting. Always allow the transmission to engage the new gear before throttling up. The engine should never be running when swimmers are near the boat. Most of the propulsion system is accessed by tilting the bridge-deck (using the electric lifts).
CHAPTER 3 3.3 PROPULSION SYSTEM LUBRICATION Both the engine and transmission use oil for lubrication. The transmission will tend to use less oil than the engine, but both should be checked frequently. For the proper type of oils to use (which may depend on the service area and conditions) consult the maintenance schedule below.
CHAPTER 3 3.6 PROPULSION SYSTEM PROPELLER The 34z uses a right-hand or left-hand propeller, depending on the customer’s preference. The primary difference is in boat handling characteristics at low speed, especially in reverse. A righthand prop will tend to pull the stern to port when backing. The same transmission is used for either prop and is factory set for the orientation of your propeller. This is easily changed if you should ever decide to switch propeller orientation. 3.
CHAPTER 3 3.9 PROPULSION SYSTEM STOPPING Before shutting down the engine, allow it to cool down by idling in neutral for 5 minutes. Then, press and hold the red button on the engine panel until the engine comes to a complete stop. Make sure to turn the key to the OFF position after the engine stops so that the engine hour meter stops. Note that if the key is switched OFF before the red button is pushed, the button will not shut-down the engine. 3.
CHAPTER 4 4.1 STEERING CONTROL SYSTEM GENERAL The helm control console is where most of the operation controls of the boat are located. Become familiar with these before you need to use them. You don’t want to be looking for your glasses and a flashlight while trying to turn on the bow-thruster at night! In addition, make sure that when you are using the boat, even if you are not using a specific piece of equipment, that the circuit breakers are on for any equipment you might need.
CHAPTER 4 STEERING CONTROL SYSTEM Consult the user’s manual for specifics about your thruster. In general, thrusters are best used in short bursts. Prolonged use may damage the motor, or at least trip the breaker. When not in a situation where the thruster may be necessary, leave it turned OFF to avoid damage. Consider the fact that your thruster gets DC power from the engine start battery, which is charged by the engine’s alternator.
CHAPTER 4 4.7 STEERING CONTROL SYSTEM SEASTAR HYDRAULIC STEERING With a hydraulic system that allows both the wheel and the autopilot to move the rudder, there are some unique requirements. For more information log onto www.seastar.com or email the technical service department at info@teleflex.bc.ca or contact the nearest distributor or Rose Marine at 978-283-0293 in Gloucester MA.
CHAPTER 4 STEERING CONTROL SYSTEM As indicated in applicable diagram in step 5 below. For unbalanced cylinders the oil level in the helm must be set with the cylinder rod fully retracted. Failing to observe this caution will result in an oil spill at the helm. Turning the wheel port (left) will retract the cylinder rod. Filling & Purging the SeaStar System This procedure requires two people.
CHAPTER 4 STEERING CONTROL SYSTEM Filling the helm full of oil can be done faster if oil is poured into the helm prior to connecting filler tube and oil bottle to the helm. Step 1 • Screw the threaded end of the filler tube into the helm filler hole. • Remove the cap from the oil bottle and holding upright, screw into the filler tube bottle cap. Poke hole in the bottom of the bottle if entire bottle is to be used. • Fill the helm pump full of oil (Oil should always be visible in the filler tube).
CHAPTER 5 5.1 FUEL SYSTEM GENERAL It is important to understand the fuel system aboard your boat. Diesel fuel is different than gasoline. In most respects it is safer, however precautions need to be taken to maintain the safety of your boat. Please study the safety precautions in the NMMA publication “Sportfish, Cruisers, Yachts – Owner’s Manual.” Diesel engines need to intake more fuel than they burn, and so they differ from gasoline engines in that they return excess fuel to the tank.
CHAPTER 5 5.3 FUEL SYSTEM CHECKING THE SYSTEM Your engine needs clean fuel to operate. Be sure to buy diesel fuel from a reputable marina. Also, check the primary fuel filter regularly. The primary fuel filter has a clear bowl that will allow you to inspect for water and sediment accumulation. You should be able to see thru the fuel in the bowl at all times. Cloudy fuel indicates a problem. Also, you should not see bubbles passing through the filter while running.

CHAPTER 6 6.1 ELECTRICAL SYSTEM GENERAL The 34z’s electrical system is probably more advanced than to what you may be accustomed. It combines DC and AC power. An understanding of how the system works will aid you in your ownership. 12 volt DC power is stored in your batteries. This power is replenished either by an engine-driven alternator or by a battery charger converting AC power to DC power. Most of the electrical components on your boat use DC power.
CHAPTER 6 ELECTRICAL SYSTEM The house battery switch can be left OFF when the boat is not used, and the batteries will still accept a charge from the battery charger. If you are leaving the boat plugged into shore-power and you wish to turn off all DC loads but still be able charge batteries. Leave the house switch ON and turn off the main DC disconnect breaker on the DC panel.
CHAPTER 6 ELECTRICAL SYSTEM INVERTER/CHARGER (Optional) There are many functions that are fully explained in the inverter/charger manual. Please read it thoroughly for a complete understanding of this unit. The 34z is also supplied with a remote panel that controls the inverter/charger from the AC panel and displays information. This remote panel has its own manual, with which you should become familiar.
CHAPTER 6 ELECTRICAL SYSTEM TRIM TAB 6.5 ELECTROLYSIS & GALVANIC CORROSION Metallic fittings that are exposed to saltwater are subject to electrolysis and galvanic corrosion. To minimize potential damage, your boat is fitted with a sacrificial zinc at the transom. This zinc is connected to the bonding system of your boat. It should be visually inspected whenever possible and replaced when 1/2 of the zinc has been eroded.
CHAPTER 6 ELECTRICAL SYSTEM Check that AC VOLTS are now reading on the AC digital meter. Turn the breakers ON for items you wish to operate. Note: if the generator starts, but no AC voltage is detected at the panel, check first that the selector switches (sliding interlocks) at the top of the AC panel are configured correctly. If this does not solve the problem, there is a possibility the generator was overloaded and the AC breaker on the generator itself has tripped due to a momentary overload.
CHAPTER 7 7.1 FRESHWATER SYSTEM GENERAL Your boat incorporates a pressurized freshwater system. [See Figure 14.5] A single 60-gallon tank supplies a pump which maintains a constant pressure in the system. An accumulator stores this pressure so that the pump does not need to cycle every time a faucet is opened. 7.2 FILLING A deck fill is provided on the port side deck and is labeled WATER. As the tank is filled, air escapes thru the vent. 7.
CHAPTER 8 8.1 RAW WATER SYSTEM GENERAL Raw water (seawater) is used to cool the engine and the generator. It is also used in the saltwater washdown and air-conditioning options. Wherever raw water enters the boat, it does so through a seacock, which is a valved thru-hull penetration. [See Figure 14.6] 8.2 ENGINE RAW WATER The engine and generator (if fitted) use separate seacocks and strainers. Before using the engine or the generator, make sure its seacock is in the INTAKE position.
CHAPTER 9 9.1 GRAY WATER SYSTEM GENERAL Gray water is liquid that can legally be pumped overboard, generally from sink drains, shower drains, and bilges. Your boat also directs deck run-off to of all gray water through common drains (port & starboard) in the transom. 9.2 GRAY WATER TANK The gray water sump box aboard your boat is located in the bilge under the panel below the bottom companionway step.
CHAPTER 10 10.1 EXTERIOR EQUIPMENT GENERAL Although all the exterior equipment on your boat was selected with marine service in mind, it is helpful to rinse the boat with freshwater after exposure to saltwater. 10.2 ANCHOR WINDLASS (Optional) Refer to the manual that came with your windlass for specific operating instructions. The windlass draws power from the engine start battery.
CHAPTER 10 EXTERIOR EQUIPMENT curtains rolled (usually several together and not folded) in a dry place to prevent creasing or shrinking. 10.4 PRIVACY/SUNSCREEN CURTAINS (OPTION) Fine white mesh allows you to see out but makes it difficult to see in. When installed at night, these curtains convert the Pilothouse to an additional stateroom. The 8 Curtain set comes rolled up in its own carry bag.
CHAPTER 11 11.1 INTERIOR EQUIPMENT MARINE VACUFLUSH HEAD SYSTEM Waste discharge regulations vary by location. Check with local authorities. The waste system aboard your boat employs freshwater and a vacuum generator. The freshwater pump breaker and Vacuflush breaker must both be on (DC panel) for the system to work. Further controls are located on a panel in the head (shown). Refer to the manufacturer’s manual for more details.
CHAPTER 11 11.4 INTERIOR EQUIPMENT MICROWAVE OVEN (Optional) This 800 Watt AC Panasonic unit offers several cooking modes which maybe operated without shorepower by utilizing the inverter for AC power and turning ON the switch on AC Panel #1. Please refer to the Panasonic Users Manual for operating instructions and precautions. The manual is stored inside the oven when the boat is initially delivered. 11.
CHAPTER 11 INTERIOR EQUIPMENT (5) Call Sirius at 1-888-539-7474 to activate, conveying the 12 digits of the Serial Number of the unit. (6) Tell them that you just purchased an MJM 34z motorboat with Sirius installed and that you understand that Sirius is offering a 1 year free subscription to new boat owners. Be ready to give them the HIN # which is etched into the upper right corner of the transom. Note: The promotion may be over by the time you do this, but worth a shot in any case.
CHAPTER 12 ROUTINE MAINTENANCE 12.1 Refer to the following chart for routine maintenance actions. Refer to the engine manual for additional actions to be taken after 1000 hrs. Some of the items you may choose to leave to professionals, but many you can do yourself. In particular, it is a good idea to have a certified mechanic perform check-ups from time to time on the engine, generator, and any other valuable equipment installed onboard.

CHAPTER 13 13.1 START OF SEASON [commissioning] 13.2 END OF SEASON SEASONAL MAINTENANCE Most facilities will not require additional information before hauling the boat with a Travelift or crane, but if this is the case, use the included Lifting Diagram Figure 14.10. The end of the season is a good time to have the bottom power-washed and to check all thruhulls and seacocks for growth. Careful inspection of all underwater hardware at this point may avoid a potential problem in the future.

CHAPTER 16 1- QUICK START GUIDE Disconnect Shore-side Connections To disconnect shore power cords, turn off all AC loads on the boat and make sure the main AC breakers on the AC panel (the double breakers) are all OFF. Then disconnect the cord at the dock end first. Disconnect the cord at the boat and close the shore power inlet cover. Ditto for any phone/cable lines. 2- Set Battery Switches The battery selector switches are under the companionway step.
7- Turn On Navigation Instruments Make sure the depth sounder is ON, then turn on the chart-plotter, VHF, etc. Some instruments do not have power switches and are turned on at the panel. It is always a good idea to bring paper copies of applicable charts and to check your compass periodically. 8- Check Lights If the boat is to be operated after sunset or in reduced visibility or fog, check that the running/anchor lights and searchlight are all functioning.
