Flushing the Cooling System
!
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.
Flush the internal water passages of the outboard with fresh water after each
use in salt, polluted, or muddy water. This will help prevent a buildup of
deposits from clogging the internal water passages.
IMPORTANT: The engine must be run during flushing in order to open the
thermostat and circulate water through the water passages.
1.
Remove the propeller. Refer to Propeller Replacement.
1. Replace the water pump impeller more often if overheating occurs or reduced water pressure is noted.
