1980 merc 85hp power tilt/trim pump

[Rustyforever]

Hey guys, I am getting closer & closer every day But!
My power tilt trim pump is a Four hose system. I replaced the hoses already, pump squirts fluid out of some kind of Relief valve hole..
replaced O" rings already...
does anybody know of a replacement pump for this system?
does anybody out there have one? internet comes up shy on the 4 hose..
Thanks in advance...steve

Gee, I cannot think of any "relief valve hole", on that system. Where is it located? You do have the knurled knob on the control valve, right?

Wow I can't believe it's been so long since I posted that, sorry I didn't get back you earlier. Anyway if your still willing, Yes it has the knurled knob. The hole in the body is intentional and there is a ball and spring in the valve body below it so it's gotta be some kinda relief valve. I have surfed the net long and hard to find 3-4 people with same issue, but no answers. So if it's not repairable or unknown to do so, do you know of an replacement pump for a 4 hose?

You would normally replace the whole control valve, if it is leaking oil. They are not repairable, as far as I know. A salvage yard may have one. A local Merc dealer may have one he is willing to sell cheap, as the demand for those is pretty low.

Ok thanks, my search has been so far unrewarding, but thank you for your response

Check ebay, kijjii or craigslist for used pumps.
