Checking engine speed
At full load (with the boat cruising) the maxi-
mum engine speed should be approximately
as specied in the table.
If the engine does not reach this speed, it is
being overloaded!
If this is the case, check the ship’s propeller for
defects or irregularities, and also to see that it
is the correct pitch and diameter.
Idle speed must be as specicated in the ta-
ble.
• Now check the speed and adjust if required.
69 Checking engine speed
• Allow the engine to warm up normally (un-
til the coolant temperature reaches at least
60°C (140°F).
• Check the engine RPM using a rev. counter,
or use the rev. counter tted to the control
panel.
Warning
The maximum engine speed adjust-
ment screw has been correctly set at
the factory and sealed. DO NOT at-
tempt to remove this seal.
