The outboard engine has a built-in trim and tilt function. The trim adjusts the angel of
the propeller versus the boat transom. See also chapter 4.6.

The engine trim is used to adjust the bow up or down (the so-called pitch) while the
boat is under speed. A well-adjusted engine trim will maximize safety and comfort, and
will minimize fuel consumption.
Mastering the trim will require some practise so if you are uncertain, ask someone
experienced for help. Correct trim is very important for a safe, comfortable and fuel
economic ride, and for fast acceleration.
The basic directions to find optimal trim are as follows, and shall be done during flat
water conditions:
Accelerate to planing speed (approximately 10 to 15 knots depending on
conditions):

Engine trim is used to help the boat accelerate as fast as possible from zero to
planing speed, with an optimal pitch. Fast acceleration to planing saves fuel and
improves the view.

Engine trim shall be at maximum trim down position directly at start.

As the boat accelerates and reach planing speed, the trim is changed from the
trim down up to neutral trim, in order to keep the bow level or at a slight upward
angle. Failure to do so will cause the bow to plow deep into the water,
preventing the boat to pick up speed and run safely.
