Side Pickup
NOTE: Flushing is needed only for salty, brackish, mineral‑laden, or polluted water applications. Flushing is recommended after
each outing for best results.
NOTICE
Flushing the engine with the boat in the water can cause seawater to flow into the engine, resulting in engine damage. Close
the seacock before flushing the engine. Keep the seacock closed until starting the engine.
NOTE: Closed cooled models are equipped with a heat exchanger on the side of the engine.
1. If flushing the cooling system with the boat in the water:
a. Raise the sterndrive to trailer position.
b. Install the appropriate flushing attachment over the water inlet holes in the gear housing.
c. Lower sterndrive to full down/in position.
2. If flushing the cooling system with the boat out of the water:
a. Lower sterndrive to full down/in position.

WARNING
Rotating propellers can cause serious injury or death. Never operate the boat out of the water with a propeller installed.
Before installing or removing a propeller, place the drive unit in neutral and engage the lanyard stop switch to prevent the
engine from starting. Place a block of wood between the propeller blade and the anti‑ventilation plate.
b. Remove propeller.
c. Install the appropriate flushing attachment over the water inlet holes in the gear housing.
3. Connect hose between flushing attachment and water source.
4. With sterndrive in normal operating position, open the water source completely.
5. Place the remote control in the neutral idle speed position and start engine.
NOTICE
Operating the engine out of the water at high speeds creates suction, which can collapse the water supply hose and overheat
the engine. Do not operate the engine above 1400 RPM out of the water and without sufficient cooling water supply.
6. Depress the throttle only button and slowly advance the throttle until the engine reaches 1300 RPM (± 100 RPM).
7. Observe the water temperature gauge to ensure that the engine is operating in the normal range.
8. Operate engine with sterndrive in neutral for about 10 minutes or until discharge water is clear.
9. Slowly return throttle to idle speed position.
10. Stop engine.
11. Shut off water and remove flushing attachment.
