When mounting dual outboard motors on "V" bottom boats, the
outboard installation height range is 0 – 25 mm (0 – 1 in (1)).
If the outboard installation height cannot be achieved, adjust boat
transom height.
BOAT TRANSOM HEIGHT ADJUSTMENT
If the installation height is too low, or needs to be modified to a
accommodate the width of the outboard motor(s), contact the boat's
manufacturer and follow their recommendations for corrective
action.
If mounting two outboard motors, be sure the installation height is
identical for both.
Some boat manufacturer's may require different mounting height.
Consult your boat manufacturer for specifics on your boat.
TRANSOM DRILLING
Verify no damage will occur when the motor mounting holes are
drilled. Lock for any structural impediments such as bulkheads,
braces, fuel cells, bilge pumps, or floor sections before drilling.
Ensure there is adequate space for the bolt, washer, and transom
support plate (if applicable), to bear on a flat surface.
Wear safety glasses and drill four 1/2-inch holes in the transom.
Drill upper holes at least 25 mm (1 in) below transom top edge.
Drill the lower holes in the positions where the top edge of the long
hole in the stern bracket comes in contact with the bolt.
Mark the center point of the 10 drilling holes (i.e. 5 holes at the right
and left sides of the transom respectively that are in the symmetrical
position with regard to the center line of the outboard installation
line).
Using a 3 – 5 mm (0.1 – 0.2 in) diameter drill, drill the pilot holes at
the marked points at right angles with the boat transom surface.
Then, drill the holes using the 13.5 mm (0.53 in) diameter drill.
With the outboard motor resting on the boat transom, verify the
correct motor height. The outboard motor can be raised by using a
lower set of mounting holes.
Use vacuum cleaner to clean up after drilling.
