Cooling system
A high capacity water pump and a large cylinder head water jacket have been incorporated to
enable better cooling.
A pressure control valve (PCV) has also been incorporated to control the cooling water pressure,
which in turn helps prevent water leakage from the power unit. When the cooling water pressure
becomes too high, the PCV opens and the cooling water flows through a bypass passage to the
upper case.
An additional water inlet, located in front of the trim tab, allows cooling water to flow into the exhaust
passage in the lower unit during high-speed operation. This extra cooling water properly cools the
high-temperature exhaust gas before it exits through the propeller boss, helping to prevent the rub-
ber parts in the propeller boss from being damaged by high gas temperatures.
