Adding/Replacing Tilt/Trim Fluid Mercury ELPTO 90hp

Recommended Posts

Any of you guys have any exp changing the tilt/trim fluid? Mine is getting to where it doesnt want to trim all the way up, and starts to slow down a lot. I took the only "screw/cap" off that I could find, and the motor was in the up position, I added some fluid till it started running out, and I screwed the cap back on. Ran it up/down a few times, and checked the level again and it hadn't gone down any. I did notice that it was "milky white" and that leads me to think that it's got some water in it, and that I should probably change out and flush it and refill with 100% new oil.

Anybody have any tips?

Once I topped if off, it started working better than it ever had, and went up/down as quick as I could want..... just dont like the idea of it possibly having water in it.

talked to the original boat owner today, and the best he can recall, he's never even looked at the trim fluid or ever had it changed. So the boat is a 95 model, and if that's the case.... the fluid in it is approx 17yrs old. It only held a thimble full of fluid when I topped it off. So I don't think there's an issue with the seals, I can leave the motor trimmed up for days and it doesn't bleed down at all. Think I am going to take a syringe with a rubber hose, suck out as much of the old as I can, and re-fill with new fluid. See how it reacts to that.
