TOPIC: Mercruiser 160 Hydraulics

Howdy all,

I am having trouble with the trim on my boat not holding. My 1967 Gulfstream has a Mercruiser 160 I/O on it. I figured someone here has a way better understanding than I do on this sucker.

Here is what's going on.

* When motor is trimmed up for trailering it will bleed down in about a 5 hours. I have noticed this while she's on the lift.

* If I grab the sterndrive and lift up and down I can get it to move about half its full travel in either direction. I can hear what sounds like air being bled when I manually lift the stern drive.

* I checked the fluid and it appears to be low.

What should I do? Just add hydraulic fluid? Do you think the system has air in it and needs to be bled if so how?


Any help is appreciated.
