Shipyard Isl. Marine Engine Parts - Possible F225 tilt/trim issue

My question is : what supports the load of the motor at rest, the main tilt ram or the trim rams?. My boat is kept on a lift and after flushing the engines I normally tilt up both motors until they clear the tilt rams and then let them back down until they just contact the tilt rams and leave it in this position. A Yammie mechanic advised that this was the best way to keep motors versus resting on the tilt stop lever. Has been fine for several years now but I am having one of the motors to tilt or fall down on it's own within a day or so. What should I be looking for first? I have seen no signs of fluid leak around the top seals, I have not checked the fluid level yet but will do so, motor trims up and down fine while underway. Thanks for any advice.

Sitting in the water, I don't think it matters where they are resting. There isn't a terrible amount of weight on them. Now trailering......thats something completely different.

I know a lot of customers that tilt them all the way up, put the arm rests down, then hit the trim down button until the short trim rods retract into the cylinders. Takes a little bit, but it keeps the rods out of the water and crud.

Hey Andy,

Thanks for the reply, the boat sits out of the water on a lift. Any idea what may be causing the TNT to Trim down on it's own while at rest?

Most likely it needs a thorough internal cleaning and re-oringing.
