3.0 GENERAL
Your 36z is propelled by twin Yanmar diesel engines turning duo-prop propellors.
The dual-lever electronic 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. Push the
SYNCH button to synchronize the engines, permitting the port throttle to control both engines… or you
can use both at the same time, although the starboard throttle does nothing.
The engine should never be running when swimmers are near the boat.
Engines are accessed by raising the cockpit hatch using the electric lift.

COOLING
Your engine passes seawater (raw water) through an intake in the sterndrive
unit under the swim platform to the impeller (pump) then through the raw water intake strainer
then through a heat exchanger where it cools the engine’s coolant. This coolant is circulated
through the engine and returns to the heat exchanger. For the engine to keep cool, it must have
an adequate supply of raw water and coolant.
