All,

My outboard is setting only when it hits the two trim rods. I started by replacing the manual release valve, with no luck. I then purchased the "quicksilver o ring kit #878408A 1" and rebuilt the tilt and trim unit. I bled it 1st when it was still in the vise, but I kept gettin a bubbly foam that would burp out of the fill hole.

I re-installed the unit only to find out the original problem wasn't fixed. It doesn't settle when resting on the tilt ram, and settles when it's resting on the trim rams. It settles about 3/4" every 10 minutes. Also, it continued to have the bubbly foam come out.

The person before me put ATF in it and I put the Marine power trim & Tilt fluid. I tried to get all of the old stuff out and wondering if mixing it is causing the bubbles

I'm not sure what else to do, and seeing if anyone has any recommendations. I can't afford a new one and wondering if should look for a good used unit.

Thanks
