    I'm looking for some good information on converting an older displacement hull (Davidson Chugger) that had a 1 cylinder diesel (beyond repair) to small 4 cycle outboard. The boat is 18' long with a 6.5' beam and a full keel. Has a flat transom, made of fiberglass and a small cabin. Replaceing the diesel, plus fuel tank, prop and shaft and various other contol parts appears to be a very expensive option. So I was thinking of using a 9 to 10 hp four stoke outboard as a possible alternative. Would a transom bracket be a good way of mounting the outboard or should I think of making a proper motor well into the existing transom. Any thoughts or possible direction to some information on this topic would be appreciated.

    Thanks

    Instead of changing to an outboard have you looked at the merc 1.7 diesel? Though bigger than a 1 cylinder it is still pretty small, puts out 120hp or so and you could keep your diesel and lines in the same place. As well it gets better mileage than any outboard you are going to put on there.

    Here is some info:
