I was boating when trim/tilt stopped working and started to whirr but no action up or down,, when I put it on trailer
and took out drain plug very black ugly oil came out, stern would not raise, with the help of my son got it up enough
to trailer home, when took out cowlings and seats I could see the trim motor on the port side, this is a 1976 model
but engine and every thing else have been replaced except trim unit,, same is black looking on a sheet metal frame.. hit trim buttons up down all I could see was fluid coming out the bottom where the preassure hose hooks up
to bottom of trim unit,, can I do the above and man handle it up?? how do I fix this myself, or should I just take it to the shop,, it does appear to be coming from the unit above the hose, the fitting was tight? whats next
what kind of expence can I expect,, I am a loss on what to do next

took it apart had nothing to loose,, took the botton off where the lines connect, two of the O rings were busted and one of the bolts was stripped out.. so would not hold preassure, went to O'Reillys got some O rings and a tap and made it one size larger,, cost about 6 bucks.. and I thought I would have to buy a new unit, I'm feeling real proud of myself! don't know how much I saved? I had taken it to a marine dealer couple weeks before and told him it was leaking.. "Said could not find anything wrong"
or maybe he's the one that striped the bolt who knows
