If you've got this combo, preferably a non step hull, could you please take a look at your aft drive ram pin and tell me which position its in (I.e. pin to the stern spacer towards bow, or vice versa)? This can be observed by looking at the ram ends in comparison with the oblong boss on the drive unit.
I just finished a gimbal bearing/bellows job and noticed the Mercrusier manual specifies that Bravo Ones should have the semi circular spacer positioned towards the bow, mine was in the opposite position which Merc states is for Bravo 2 and 3 only.
I can't tell if Donzi set it this way on purpose or if a prior servicer swapped positions unknowingly.
Thanks
