PROPULSION SYSTEM (Optional Volvo-Penta Twin 220A-DPS Engines Shown)
3.1 GENERAL
Your 36z is propelled by twin Volvo 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. If the two levers are
set to within 200 RPM of one another, they will automatically synchronize.
The engine should never be running when swimmers are near the boat.
Engines are accessed by raising the cockpit hatch using the electric lift.
3.2
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 strainter 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.
