IMPORTANT: Ensure that the water cooling exit ports are securely
attached. Failure to inspect them can result in excess water entering
the hull.
CAUTION: Water cooling happens only when the jet pump is
pushing water. Do not leave the boat stationary for long periods
of time as it can cause excessive heat and cause damage to the
electronics.
