90 Mariner/Mercury ELPTO Power Trim

Guys, Gotta help me.

The power trim come with very stranges sounds from time to time. I bought the engine used and it is like something that needs lube. It is not all the time but about 50%of the time.

It works perfect.
Anybody who have experience with this ?

Thanks in forward

Cheers Thomas

Have you checked the power trim fluid level? If it gurgles there's a chance you may need to top up the system then purge it of air. Lift the engine, the fluid reservoir will be there. Don't mix fluids. Refer to owners manual for correct specification.

I thought I had a dodgy power trim unit on engine I bought. Erratic operation, slow to lift juddering and generally sounded pretty bad! Turned out it was a virtually seized tilt tube, had to strip the lot down to free it off. Works great now. Just goes to show what the wrong grease and lack of proper servicing can do.

Not saying that's whats wrong with yours but worth checking and greasing anyway!

Thanks, so you mean I have to clean it and grease it up ?

It sounds like the tilt pump need oil but only half of the time and mostly when it goes down.

The level of fluid is ok.

There should be a manual release screw located on the left or right side of the pump towards the bottom. you gain access through outboard bracket. The relief will have a retainer clip so it cant be screwed all the way out you will have to remove this then unscrew the valve either a flat head or hex. Tilt the outboard up an put the trim lock on un ,unscrew manual release with a drain bucket nearby and the undo the filler cap on the pump. Once drained repeat in reverse . Then fill pump reservoir up with oil (ATF ) to the top an place cap back on . Remove trim lock be careful outboard may drop suddenly , once all the way down trim up an down say 10 times an check level top up it up an repeat till air is removed. Hope this helps
