Water Pump
The water pump is operated from crankcase
pressure. Be sure that water is exiting the 2 water
jackets mounted on the left side of the boat when
the engine is running and the boat is in the water. If
water does not stream out of either the exhaust or
cylinder head cooling ports, immediately stop engine
operation and remove obstructions in the lines or
replace broken cooling lines.

Hint: To test each cooling line
for obstructions or a leak in the
cooling system, place a piece of
tubing over the water inlet tubes
in front of the rudder and blow
into the tube. When testing for
obstructions in the cooling system,
be sure to isolate each system by
pinching the appropriate water lines.

Manifold Cooling Jacket
The exhaust system is cooled independently from
the cylinder head. See line drawings for proper
cooling line routing. Do not alter the cooling line
routing method.
