I have a 1975 vintage boat, motor (65 HP 3 cyl.) and power trim that I'm in need of rebuilding the cylinders. Anyone know if rebuild kits are available?. I imagine if push came to shove "O" rings are available with maybe the exception of whatever is in the top of the cylinder housing and the seal. If kits are not avail. is there a standard "O" ring in the top of the cylinder housing that get munched in to place or is it some special shape? Also, any thoughts on the seal other than trying a hydrolic shop?<br /><br />Thanks<br />Phil
