SECTION TWO
ENGINE COOLING
NOTICE: Running engine without adequate cooling can cause
engine to overheat and may result in fire and/or explosion.
Overheating the engine can cause severe damage or failure that is
not covered by Indmar’s Limited Warranty. Engines have two water
pumps. One circulates coolant throughout the engine. The other
pump uses water from the sea, lake or river to feed raw water to
the engine. This raw water pump is designed to use the water it
pumps to lubricate its impeller.
Do not run the engine unless the boat is in water. If you run the
engine with the boat out of the water, the water pump may be
damaged, causing your engine to overheat or start a fire. This will
void the warranty.
