tilt and trim leaking?

[Greg Ross]

I have a 1991 Ski centurion Barefoot Warrior, with a Yamaha Pro V 200 motor
Model P200TLRP, Serial #300775

I usually leave my motor trimmed a little bit to keep the lower unit out of the dirt, but lately it wont stay up. Is there a rebuild kit to replace the seals in the tilt and trim unit. I have not noticed oil anywhere, but assume it is losing pressure somewhere, after 21 years it might need a little maintenance. Thanks

I think they can leak internally from one side of the trim cylinders to the other and that would cause the motor to lower. If you don't have a shop manual you can download one online (I did for my 2001 F115) and then see which seals and O rings to order.
