Motor Fixing; Trim Angle Adjusting - SELVA MARINE MADEIRA 40 Owner's Manual

MOTOR FIXING

Model with Swivel Bracket
After having put the motor in the correct position, clamp the screws of the
levers. Then make two holes in the transom in correspondence of the
holes in the fixing brackets. Apply some dope on the holes made and on
the screws to be used to fix the motor (which are with the motor). Insert
the screws and the washers so that the nuts are inside the boat. Then
clamp very well.
Models with Shock Absorber-Power Trim
After having found the correct fixing place of the motor, make four holes in
the transom so that they are in correspondence with the holes in the fixing
brackets. Then apply some dope on the holes made and on the bolts
(accessories). Insert the bolts from outside of the transom and screw the
bolts clamping them very well.
Use only bolts, nuts and washers which are in the motor
packing. If you need to use other components, be sure that they are of the
same quality regarding the material and strength. Tighten the bolts and
check the tightening of bolts and levers after running the motor.
For the models with Shock Absorber and Power Trim, the two screws
that are in the brackets are used only to keep the motor while fixing it
and you have to take them away when you've fixed it.
We suggest you to ask for the help of skilled people to make he
operations over described.

TRIM ANGLE ADJUSTING

The trim angle is the inclination angle, that should be given to the motor in
order to obtain an optimal performance from your boat.

The trim-angle adjusting is automatically made and regulated through the
utilisation of the Trim.

An improper trim angle does not only affect the performance of
your boat, but can also cause loss of control, which means
danger for the people on board.
While sailing the motor should be perpendicular to the water
surface, but the trim angle can be 3 degrees to 5 degrees.
If the trim angle is made too great, the buoyancy centre of the
boat will shift towards the stern. In this condition, and if the
stability moment at the bow is large, the boat will tend to
"porpoise". If the trim angle is insufficient, the bow may
"plough", making the boat unstable.
When the boat is in stable trim it remains parallel to the water.
