6.3.3
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 di-
rection 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 ap-
proaching 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.
6.3.4
Adjusting of 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 en-
gine 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 econo-
my, 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 provid-
ing 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 be-
come unstable when turning if the bow is too low.
The trim tabs can be used to adjust the boat’s heel to make the boat run in an upright position in
crosswinds or with an unbalanced load.
All planing boats lean into the wind, but the heel can be adjusted by lowering the windward trim
tab. This makes the boat’s sharp bow cut the waves, resulting in a much smoother ride. If you want
to further reduce the waves’ effect on the boat, you should trim the windward side up to lift it above
the waves to an extent.
