POWERHEAD

WATER COOLING SYSTEM

WATER COOLING SYSTEM

The water cooling system consists of the water pump (in the midsection), the water tube (between the
midsection and the powerhead) and the thermostat (in the cylinder). This system cools both the power-
head and the exhaust.

If overheating occurs, the components of the cooling system must be inspected for blockage, corrosion
build-up or damage.

When open

Driveshaft housing

Exhaust outlet

Thermostat

Exhaust water
