ENGINE BED
Distance between starboard and port engine mount is 22-1/2 in. (572mm). Engine bed must
position engine so that a minimum of 1/4 in. (6mm) up and down adjustment still exists on
mounts after performing final engine alignment. This is necessary to allow for realigning en-
gine in the future.
NOTE: Although the engine mounts allow some adjustment, it is a good practice to insure
that the front and rear mount locations in the vessel are in parallel planes. This may be
checked by tying a string from the left front mount location to the right rear mount location
and another from right front to left rear. The strings should touch where they cross
.
