Okay fellas' here's the deal. I have a 69' Wellcraft with an Evinrude 85 horse Starlite, and hydro electric shift.My problem is no reverse,I think my wiring and solenoids are working because it really sounds like reverse is trying to engage.kinda like a grinding going on in the lower unit.the local boat mechanic says my reverse gear is bad and something else, not really sure. I feel as if he is scamming me because, he just wants to exchange my lower unit with another "used" lower unit. And charge me close to 400.00 bucks because he says there aren't any parts to be found anywhere.Is it possible that the lower unit just needs oil,or is it serious? Any help would be greatly appreciated.
