      I agree Mike, and I am very interested in using the drive
      system Tom C. just described in my Tolman Seabright skiff.

      My boat's a lot heavier than Robb White's boat of course, so
      I want an engine that's bigger than 20 HP, but if they are
      available up to 35 HP I guess that's no problem.
