Re: no reverse
Do a search on the Mercruiser/Volvo webpage here. That reverse lockdown mechanism is somewhat difficult to work on...springs get broken, other parts get worn down and then you get that kick up effect. Don;t drive it that way or it will break other parts of the drive by the kicking up and pounding down action. Start the new thread on that webpage with something like, VP 270 reverse lockdown problem.
good luck,
Joe
