14. Make sure the bar arrives to the end of stroke and
touches the screw (item 16 of Figure 15)
15. Turn the bar by hand checking the absence of friction or
jamming.
The engine is aligned correctly only if the bar slips
easily in position. In case of rubbing it must be
aligned again!
16. If the alignment is not correct, operate on the adjusting
nuts of the anti-vibration mounts and realign the engine,
and then repeat the steps from point 13.
A small engine setting for perfect alignment can be
performed exploiting the grooves of the engine
support.
17. Remove tension from the lifting chain, resting the engine
only on the anti-vibration mounts and the transom.
18. Tighten the supports to the side members.
