CIRCUIT
CAUTION: All hoses and fittings of the cooling
system have calibrated inside diameters to as-
sure proper cooling of the engine. Always replace
using appropriate Bombardier part number.
The 947 engine has a conventional cooling sys-
tem. The water is entering the engine by the water
inlet fitting at the 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 inlet fitting at cylin-
der head.
1. Water supply hose
Water circulates through the one piece cylinder
head which features improved combustion cham-
ber and better spark plug cooling.
Water enters cylinder block water jackets and is
directed to the water jackets of the exhaust man-
ifold and tuned pipe head through passages located
above and below exhaust ports.
1. Water passages
Water exits tuned pipe water jackets through an
outlet fitting.
1. Engine water outlet
Water circulates in the water outlet hose and is
expelled out of the cooling system through the
flushing connector located on the jet pump sup-
port of the boat.
