by Shawn
(Lake Ariel Pa.)

I got an 1987 125hp force and The other day I was out fishing and I noticed oil slick in the back of my boat.
Well I got it out of the water and put the trim up and it started to come down on it own.Well I got it home and push down on it to see if I could see the leak.Well there she was coming out of the center trim cylinder so I got the six bolts out an hour later and found that ther are seal in there well I got the old book out and its telling me that there are three seal and I found only two.Can someone that know anything about this trim o ring thing please help me.Also I was told I can get the o rings from an autoparts store. True or False.


Thanks Shawn
