    Mercruiser 888 lower shift cable routing

    Re: Mercruiser 888 lower shift cable routing I just did my cable and tried a few paths. I think bending up behind the pipe is too sharp a turn. I think the route Chris suggested is good. I do think the Gen2 diagram is usefull though, even though the gen2 shift plate is on the starboard...

    1979 Century with MC 1 transom, MR Drive. I replaced all my hoses and bellows less than 1 year ago. Yesterday I noticed water in the bilge. I found the shift bellows split away from the pinch clamp end. I wondered if I extended the bellows too much before clamping and put undue stress on the...

    Bent Skeg

    My skeg has a gradual bend when looked straight on from the back of the drive. It is sort of a rounded bend mostly on the last 3-4 inches. If it were steel I would rig up a bar or something to bend it back. I want to know if the aluminum will bend with pressure or is it brittle enough to...
