MAINTENANCE

Flushing Cooling System

WARNING

Avoid possible death or serious injury. Always remove the

propeller before flushing the cooling system.

CAUTION

Avoid engine damage from overheating. If the engine is operated

above 1500 RPM during flushing, suction created by the

seawater pickup pump may collapse the flushing water hose

causing the engine to overheat.

To prevent silt and salt build‑up in the cooling system, flush with

freshwater.

1. Install a flushing hose from a water tap to the flushing

connector/water pick‑up. Consult your boat owner's manual

for the location and procedures for water connection.

2. Completely open the water tap. Place the remote control in

neutral position and start the engine. Operate the engine at

idle speed, in neutral, for about 10 minutes or until discharge

water is clear. Stop the engine, shut off the water, and remove

the flushing hose.
