947 Engine
The 947 engine has a conventional cooling sys-
tem. The water is pre-heated in the tuned pipe wa-
ter jacket before entering the engine or cylinder
head.
As with other models, the water supply is provid-
ed by a pressurized area in the jet pump between
the impeller and venturi.
Water is directed to the water jacket of the tuned
pipe head.
1. Water supply hose
Water circulates in the jackets of the tuned pipe
head and the exhaust manifold. It is consequently
pre-heated by the exhaust system.
Then, water enters the cylinder-block water jack-
ets through passages located above and below
exhaust ports.
