The boat was running fine when suddenly it stopped. The engine works fine, the outdrive seems to work fine. There was a smell of rubber and hard rubber chunks were found at back of engine. Does this sound like the coupler gone bad. If this seems to be the problem I need to know the difficulty in changing this out and maybe somewhere I can get a schematic showing the part. This is a 4.3 OMC 1986 model sn/ t0007738 any help with this would be greatly appreciated.
