OPERATION
56
NOTE: When the engine is being run within the RPM range of
3500–4200 RPM, there may be a slight RPM instability. This is
caused by the light engine load conditions normally seen with jet
lower units. This condition will not cause any adverse affects on
the engine.
NOTICE
Without sufficient cooling water, the engine, the water pump, and
other components will overheat and suffer damage. Provide a
sufficient supply of water to the water inlets during operation.
1. Ensure that the driveshaft bearing on the jet drive is lubricated.
Refer to Maintenance ‑ Lubrication Points.
