    Any idea whether a suitable bell housing would be readily available for eg. the Hatz 2W35 diesel?

    17 ft.

    I own an open 17 ft. Drascombe Driver, with a 9 hp aircooled Kubota petrol inboard engine. Very lightweight installation without gearbox, but with feathering (forward-neutral-reverse-sailing) propeller. Absolutely fabulous. If I would know how to post a photo here, I would.

    P.S.
    Thanks for the How-to, Apex1. It works splendidy now, I used to have problems before.
    And JotM: Sorry, the Sea Raider has no inboarder -yet-. ;-)

    Claus,

    While you are at it, I would love to see pictures of your SeaRaider as well!

    Claus, Watermota no longer offers that little gadget as handy as it might seem. I've seen other similar units.

    PAR,
    what similar units have you seen?

    I thought the Watermota system is/was unique in its straightforwardness and lightweight. Being without reversing gearbox AND the ability to feather the propeller to zero drag is the key for inboard systems to be suitable for small craft. I thought there is no other system on this planet without separate reversing gearbox.

    But the Watermota system was designed in the sixties, using machined bronze cast parts, which made it all expensive. Looking at it with the eyes of a value analyst, I am convinced it could be done simpler and cheaper today if done using welded stainless steel commodity parts.
    But, is there really a market for such small inboard systems?

    P.S.
    My 9 hp installation, all included, weighs around 35 kgs. AND that weight is low down in the hull, and the propeller is in the hull centreline, all quite ideal so. Which all results in the boat also retaining good sailing properties, it BTW won the Drascombe class overall in Sail Caledonia 2006. You would have thought small sailing boats with inboarders could not do such.

    light as a feather

    Pretty amazing! That beats many, if not most or all, 4-stroke outboards.
