Paul,
    Has anyone ever put a 13B on an outboard motor? I have a blown big
    Evenrude, and
    was just pondering ideas.

    Regards,

    Not that I know of but that is a great idea. With aluminum end houses it
    might
    weigh about the same. You would need a dry sump pump to handle
    the oiling system. With a turbo it would be one spectacular out board.

    How much HP was the Evenrude? New big Evenrudes are about $15,000

If  memory serves me correctly, OMC spent a great deal of time and money developing a rotary outboard. It Rocked!!!, However, I think that had problems in two areas that prevented it from coming to market.

1. the vertical  orientation created problems with lubrication

2, ecologically it was not great as in oil in the exhaust and "oil slicks" in the water.

I occasionally have lunch with x- OMC guys and I will try to find out more about it when we meet.

That is a possibility. The vertically orientation could cause problems
with oiling.  But I don't think that is insurmountable.  A dry sump pump IMHO
could do the job. Sachs built a lawn mower with a vertical engine.

All two cycles had that oil in the water problem. Somehow Mercury and maybe OMC
solved it. Two cycles out boards are still available I think.

Maybe not in California :-)
