Flushing the Cooling System
Flushing the cooling system is essential after each use in saltwater, after the boat has run aground, or when the overheat warning
horn sounds. When using the flushing attachment, ensure that the water is turned all the way on and flowing through the engine
before starting.
IMPORTANT: When using the flushing attachment do not run the engine above idle.
!
CAUTION
Never start or run the jet drive without water circulating through the cooling system to prevent damage to the unit.
a - Flushing attachment (hull mount)
b - Flushing attachment (engine compartment mount)
1. Locate the flush adapter in the boat. Some boats may have the adapter mounted in the hull or mounted in the engine
compartment.
2. With engine "OFF," remove the cap from the flush adapter and attach a water hose.
IMPORTANT: Do not run the engine above idle when flushing.
3. Turn the water on all the way. Start the engine and flush the engine block for at least 10 minutes.
NOTE: An insufficient flow of water to the engine may cause the engine to overheat. If the warning horn sounds, stop the
engine immediately and allow to cool.
4. Stop the engine, turn off the water, and remove the water hose from the flush adapter. Install the cap and tighten securely.
