I'm hoping you experts can once again help me with some expertise.
My '99 C90 Serial L/500718/U has been acting up and getting air in the hydraulic fluid. I realised I had a problem when it sometimes refused to tilt down until I dropped it with the manual release valve. I changed the fluid and bled it to no avail and then found a leak out of one the dust seals of the twin up trim pistons.
First question it seems from the yam workshop manual I have to take the engine transom brackets apart to get the whole T&Tunit out? This looks like it means taking the engine off the transom or is there another way? If I only replace the seals on the known leaking piston I think I can get that out with the T&T unit left in situ and is that likely to cure the hiccups?
Looking at the online parts catalog on iBoats there doesn't appear to be a rebuild seal kit or is there? I'll probably try replacing the seals I can see are leaking but may need to replace all seals from the ground up. Maybe a Winter job!
Regarding the leaking piston the parts listing shows only a dust seal 6H1-43822-10-00 but there has to be an O-ring inside the Trim Cylinder Screw 6H1-43821-11-00 or do I have to buy the screw with buit-in O-ring?
Sorry for the length of the posting but just trying to get all the info and options up first time. Many thanks for any help and advice you can offer.
