Flushing the Seawater System—Inboard Models
Flushing the seawater system with fresh water is needed only for applications operating in saltwater, brackish water, polluted
water, or water with a high mineral content to avoid salt or silt buildup. For best results we recommend flushing the seawater
system after each outing. After each operation in saltwater and before storage, the seawater cooling system must be flushed.
With the Boat out of the Water
Without sufficient cooling water, the engine, the water pump, and other components will overheat and suffer damage. Provide
a sufficient supply of water to the water inlets during operation.
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.
1.
Remove the propeller. Refer to the boat manufacturer's instructions.
2.
Disconnect the seawater inlet hose from the seawater pickup pump connection.
3.
Using an suitable adapter, connect a flushing hose from a water tap to the seawater inlet hose connected to the seawater
pump inlet.
4.
Partially open the water source to about 1/2 maximum. Do not use full water pressure.
5.
Place the remote control in the neutral, idle speed position and start the engine.
