Trim/Tilt Leak 1999 Yamaha 130hp SW Edition

[cbujard]

My Trim/Tilt has a slow leak that appears to be coming from the rear part of the assembly -- no trace of leakage from the rams. If I fill the unit with fluid it works fine for a week or so.

Do I need to remove the entire assembly to isolate and are special tools required to remove?

Thanks.

Will have to remove engine from boat or loosen starboard side transom bracket and slide over about an inch on transom, will need to support engine to keep it from falling. Then can remove power trim unit.
