    1988 mariner 90hp cable adjust

    Not really any difference. When I pull it to full throttle and release it goes back to the same spot it'd be at with the cable attached about a half inch before the stop

    Johnson 70hp issues

    If only. I did tear into it and found my pinion and forward gear ate up a good bit and looking closely at the inside of the case the slots where the snap rings go busted a chunk out. I believe this aluminum chunk made its way around and messed up my gears and allowed water to get by. I have a...

    Johnson 70hp issues

    took it out for a test run. Still has some whine. Doesn't start until half throttle. I am able to shift properly and get max speed. Does not whine on muffs. Attached is a small video of it. Did check the oil in lower unit not really any shaving on magnet.

But if it hadn't been answered before yeah you can use the case and internals from a 4 splined pre 88 motor all is the same except the reverse gear wouldn't go on the...

    Johnson 70hp issues

    I got it all back together but for some reason I cannot spin the prop shaft freely in neutral i can spin it but i have to use a good bit of force. I was able to spin it freely until I put the 4 bolts in for the prop shaft bearing. I was pretty sure I assembled it correctly and the shaft bearing...
