hey, i have a leak where my trim lifts the motor. i was wondering if theres a good online source that would allow me to read up on the seals. hopefully a diagram that shows all of the parts so i can figure some things out. if not, i'll have to take it to a marina.
my boat is an omc 3.8 litre v6 with an omc 800 outdrive... if that helps narrow it down.
one more thing- is the fluid in my trim motor the same as power steering fluid? can i use that?
thanks guys

is sounds like its comming out of the piston?if it is you mostlikely have to replace it since most of them are a sealed unit,give me a little time and i will check into it>

thanks a lot! the boat mechanic i talked to today said the o rings on it have to be replaced. to do that he says you have to lift the motor and put a support under it, and then replace them. the labor on this is expensive he says. does that sound right, or is this guy going to rip me off? i think i'll go without a trim before i spend too much on it! thanks for your reply.

Your seals are blown bro. If it's an older motor, probably dry rotted or sun damage. Check out this link:

That will take you to a site where you can order OMC repair manuals. Just match up the particular year and make of the motor with the according manual needed.
No, power steering fluid is different. If i'm not mistaken, though the density is similar, the "hydrolic" fluid associated with your trim is designed to withstand alot more "stress" than what automotive power steering fluid is. So make sure and put back what ever the repair manual you'll end up having to buy recomends.
Also, alot of times when you get repair marine parts, believe it or not, instructions come with the product. I'd check out some wholesale marine parts dealers online and ask if they offer repair guides with the specific parts you'll be needing.
Along with greasing my bearings on a regular basis, I make sure all the rubber seals that are exposed have a coating of oil on them. I have a jug of used motor oil I keep a cap on and I use old motor oil to keep them soft and prevent dryrot. Motor oil is like vasaline intensive care for any kind of rubber seal or cover.
Make sure you're using a high quality grease for your fittings on your motor as well. One way to check the quality of the grease is to see what the "dropping point" is. The dropping point is what temp the grease looses it's integrity. I look for atleast a 550 degree F. dropping point, or I don't waste my money. You should have grease fittings on your motor where the turning rod is and anywhere else there is friction or mechanical occurances.

prices for marin stuff is nuts,i don't know how they can justify the cost differanceto me it shouldn't cost that muchbut, i am not a marine machenic i would look into replaceing the whole piston,just to see if it would be cheaper.i am a heavy equipment operator, i had a cylender,blow its cookies and hydrolic fluid went everywhereit was accually cheaper to replace a 200 pound cylender that it was to buy the rebuild kit,go figure

thanks for the advise, ill check into that. i called the marine mechanic i usually ask but he was gone fishing. i'll give him a call around the middle of the week and try and get some estimates. i really appreciate you guys helping me out on this! the good news is- other than the trim leaking the boat is running great! i wish i could say the same for the fishing thus far- all well.
