Sea trial
Check when test running the boat:
- Instruments
Check engine rpm, oil pressure, coolant tempera-
ture and charging voltage
- Check engine installation for water, coolant, oil and
fuel leaks
- Check if the maximum engine speed can be ob-
tained, see the
Owner’s Manual.
Should the maxi-
mum engine speed not be obtained, the wrong size
propeller might be installed. Also, the boat might
be loaded in a way that results in a bad running at-
titude position in the water.
- Exhaust backpressure. See chapter
Exhaust sys-
tem, Backpressure
, page78.
- Propeller shaft bearings and seals: These should
be at a low temperature and without leakes.
Check over the whole speed range:
- That the engine room temperature is kept at an ac-
ceptable level
- Abnormal noise and vibrations
- Verify that the steering and controls are correctly
connected and correspond to the boat’s move-
ment.
