This may be a no brainer for a lot of you guys but I'm pretty new and don't mind asking something that I don't know. I am replacing the small 12 volt motor that runs the worm gear which in turn runs another gear which raises and lowers the prop, however in the process of checking things out i noticed that the clutch assembly and gear that raises and lowers the prop is in an oil resevoir and it is bone dry, so my question is what kind of fluid/oil do I use within this resevoir? Thank You guys a buch.

Is this a 1997 Yamaha sterndrive with the twin BMW diesel engines?

sounds like an OMC stringer and if so, that ain't your trim motor. It is only the tilt. (a mistake that destroys the ball gears and upper gearcase) and any heavy oil you have laying around- lower unit oil fine

Sorry about the confusion... It is the tilt motor and it is on a '78- early 80's OMC 4 cylinder inboard.

My '84 stringer 800 had "10W30" stamped on the cover, but it's not critical what you use, just so it has some oil in it to resist water coming in.

Tilt clutch cavity. They leak, oil out and water in. Fact of life, get used to it.

That said....Some pack with marine grease and say it is good. I use oil but check mine every outing or 2 and drain and refill.

Problems with these...oil get in and floats the oil up the shaft into the motor and as you found out it ain't good for the tilt motor.

Solution, drain water and refill oil often.
