BOAT CONSTRUCTION
Engine Bed
The engine bed should be a horizontal type and rigid
enough to maintain engine alignment at all times.
Distance between the starboard and port engine mounts
is 22 1/2 in. (57.15 cm). The engine bed should support
the four (4) engine mounts in such a manner so that a
minimum of 1/4 in. (0.64 cm) up and down adjustment
still exists on all the mounts after the fi nal engine
alignment has been performed. This is necessary to
allow for realigning the engine in the future.
Use adequately sized bolts to attach the engine to the
stringers or mounting plates. It must be remembered
that all the force used to drive the boat through the water
is transferred to the hull through the engine bed. Make
sure there is adequate clearance between the underside
of the engine and the hull.

specifi cations:
A. 12-volt marine type
B. Tapered post connections
C. Reserve capacity rating of at least 100
minutes
2. Select the proper size positive (+) and negative
(-) battery cables using the chart. Battery should
