We have a 60 hp 4 stroke big foot Merc on our pontoon boat. It's either an 08 or 09. Anyway, the motor will tilt up but not stay up. It slowly goes back down on it's own. What do I need to check or where should I start? Thanks in advance

Re: Tilt issue

it is only supposed to go 1/3 way while the prop is spinning.
If it won't stay up while motor is not running then one of the springs or seals in the hydraulic pump has probably gone bad.
I have also seen this problem on Canadian engines due to hard freezes causing internal cracks.
There probably is not an easy fix if it is drifting down with motor off.
If it is a simple seal/spring then $100ish repair.
If it is a split housing then $300-400ish repair.

Re: Tilt issue

Thanks guys. Unfortunately the boat is 250 miles away right now. I'm going up there in 2 1/2 weeks and I'll see what I can find.
