    It had a dog-clutch which allowed you to move it from neutral to forward. That was all. If you needed to go in reverse you stopped the engine altogether, then started it again by pulling the flywheel round backwards -- instant reverse....

    You removed the magneto altogether and took it ashore with you to stop the vessel being stolen.

    What a nice little motor that is.

    I'm not sure if this is considered bad form on a forum but I wanted to give this old thread a bump and see if there had been any developments in this department in the eight years since the last post here. Has anyone recently built or heard of a boat with an inboard diesel small enough to live on a dinghy dock? 15 feet or less? 12 or less maybe? This is a real pipe dream of mine! One of these days!

    These are cheap enough you could buy two. You just have to wait for the boat from China. 77# 2600 rpm. You’d need to figure out the transmission. Belt drive and a centripetal clutch?

    With the advances in electric propulsion and emissions concerns I think India or China might be the only future for really small diesels.

    Ok, so that little Chinese diesel is pretty neat. At $100 it would almost be worth finding four other guys to go in and order five of them (the min. order qty). I wonder what shipping is though? (Probably $500 each. Lol )

    This thing,

    242DBA95-C5D4-4AB9-AFE5-3975C3F74B4D.jpg
    which weighs 770# and costs $930.00 costs $854.00 to ship from China to North Carolina so my guess would be shipping wouldn’t be too bad.

    there's two cool little lister-petter diesels on craigslist right now:

    a westerbeke DS5 which weighs less than 200lbs

    and an air-cooled model AC1

    FWIW, I made a British Seagull into an inboard (converted the mix to 20:1)
    It weighs 40 lbs w/ gearbox and shaft...

    Hi,

    I think this motor is not used to drive the dory. He's just a halibut substitute!

    Better idea might be to buy all four and carry three spares, quality won't be impressive

    Shipping those little Chinese diesels is between $700-1000. From aliexpress.
    Offsets the cheap motor cost bigtime.

    That’s crazy expensive. I was talking with a friend today who had 200# of lab equipment shipped to Minnesota from China for $280.00. It took almost two months but still.

    I had a 1,000 lb Buda diesel marine engine shipped from Seattle, WA to Lexington, VA for about $250. Did it through FastenAll. No hassle and reasonably quick.

    I have that exact chinese water cooled diesel posted above. Cool engine, but quite big, and more importantly LOUD. Like really really loud.


    I have a couple air cooled versions that are about the same decible level, but are more compact.

    This is Atkin's Begaduce, 14' I believe. The engine shown is 10 hp, which is way too much. I recently swapped it for a little 3hp which fits the boat better.







    I wear ear plugs while powering. It's okay for a work-ish boat. I power out to to where I want to drop some crab pots, then kill the racket and set or pull pots under oars. Really, the dream is switching to electric power. It makes a lot more sense for a pleasure boat.

    A lot of nice boats here, but I really like Bally, another "opduwer".
    She's not very practical, just for fun.

    but isn’t “tinkering” half of what really small inboards is about?

    I do have a little 5 hp Acadia make and break that would be nice to put in a boat. “Little” being relative as a 5 hp Acadia weighs 300 pounds!
