Ok so I've done research and nothing really explains my problem. I have a 92 190 chaparral with a 4.3. Previous put a new motor in it and didnt align the engine and trashed the coupler. I have replaced the coupler with the new style (grease fitting) and new drive shaft, I also replaced the nylon...
I have a 86 Chris craft with a 140 mercruiser. I just purchased the boat and it takes forward smooth but trying to go into reverse it just grinds and never actually engages and then the engine will die sometimes. I've not tried anything yet but just looking for opinions before I tear into it.
