5.9.3 Gearshift and throttle
The engine is put into gear by pushing the button on the gear/throttle handle upwards with
your fingers and by pushing or pulling the gear/throttle lever forward or backward,
depending on the direction in which you are planning to go. When the engine is in gear, you
can adjust the boat’s speed using the same gear/throttle lever.
When the boat is travelling forward slowly, you can use the reverse gear for braking when
approaching the dock, for instance. Shifting into reverse must not be done if the boat is
travelling at higher speeds, because it will damage the engine.
5.9.4 Adjusting the trim angle
These are the main rules when adjusting the trim angle:
- When bringing the boat to plane, keep the ‘bow down’ position.
- When the boat is planing and seas are calm, keep lifting the bow until you can feel
that both the engine and the boat move very easily. In calm waters, the engine
should normally be trimmed up at least 3 scale marks on the trim indicator on the
revolution counter. If the engine is trimmed up too much, the speed of the boat will
be reduced. If the boat is trimmed too low, the boat will run slowly, and the engine
will run heavily. To achieve good fuel economy, it is important to drive the boat with
the right engine trim angle.
- In heavy head seas, lower the bow to allow it to slice through the waves better, thus
providing a smoother ride.
- In following seas, raise the bow to avoid ‘diving’ into the waves.
WARNING! Do not drive the boat at high speeds with the engine trimmed up
(bow up), as there is a risk of sudden heeling when the propeller
hits the water again after a flight in heavy waves. Likewise, do not
drive at high speed with the engine completely trimmed down
(bow down) since this can cause the boat to pitch unexpectedly
when the bow hits the water. The boat may become unstable
when turning if the bow is too low.
