CIRCUIT
The water supply is provided by a pressurized area
in the jet pump between the impeller and venturi.
The water flow is controlled by a reducer located
between the jet pump support and the jet pump
on the inlet side. The reducer is color coded ac-
cording to watercraft model. Refer to JET PUMP.
Water is directed first through the intercooler or
to the exhaust manifold fitting located at front of
manifold for the models without intercooler.
