Re: 1975 Sea Ray Trim pump leaking. Can I fix this?
yer gonna have to look for the leak. remember, fluids run downhill. so keep looking up till ya find it. with that said. mine was leaking too. i thought trim hoses at first. ended up being the manifold the trim hoses screw into.
under that manifold are 4 small orings. they can be replaced. and that was where my leak was at. i didn't remove anything other than the manifold. trim hoses still connected. R&Red the o rings by using waterproof grease to hold them to the bottom of the valve body since it was up side down.
basically, the bottom of the trim pump motor is the reservoir. see attachment for fill location.. when filling, be sure drive is all the way down.
as for bleeding, run it up and down a few times. this will bleed it i believe. if that don't work. there's a blurb in the service manual about it. i'll have to read it again to enlighten you. or ya can get your own service manual. mercruiser c-90-71707, service manual #2. it has the procedure in it.
