Technical data

47
At full load (with the boat cruising) the
maximum engine speed should be about
3600 RPM (see technical data page 62). If
the engine does not reach this speed, it is
being overloaded!
If this is the case, check the ship’s pro-
peller for defects or irregularities, and
also to see that it is the correct pitch and
diameter.
56 Checking engine speed
The engine idling speed should be
900 rpm.
Allow the engine to warm up normally
(until the coolant temperature reaches at
least 60°C (140°F).) before checking and/
or adjusting the idling speed.
Check the engine RPM using a rev. coun-
ter, or use the rev. counter fitted to the
control panel.
57 Adjusting engine idling speed
If the engine speed differs from that stated
above, it must be adjusted.
The engine idling speed can be reset
using the adjustment screw on the fuel
pump.
