Engine runs, prop won't turn

[ghseaford]

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.

Sounds almost like a textbook example of it to me.<br /><br />dougrussell's website has parts diagrams.<br />To the best of my knowledge, the motor will have to be removed. At the very least, loosened and moved forward quite a bit. The coupler will be bolted on the flywheel. With the shaft from the drive sticking in it. Of course the drive must be removed as well, but that's obvious.

Ayuh,........<br /><br />Once the Outdrive is Off,+ the Motor is Out of the Boat,.......<br /><br />It's an Easy Repair..........
