    Hi Ian, thanks for your thoughts.
    The couplings I have see 19mm dia and about 25 mm
    Long.
    Always take care to align the shafts.
    As it is about to rain think can spend an hour or so fitting one.
    Will advise experiences next week after my water tests,

    Hi Rowen and Doug,
    Let me shed a little light on this subject for you. As a retired Mining Engineer the Coupling you are looking at is a high torque coupling and doesn't take to misalignment. Putting large drives together we always had the inputs on the winder drives use a pin coupling or hooke coupling where we would get misalignment (due to motors magnetic centres) The output coupling were always similar to the ones you intend to use. They carry a high torque but don't like misalignment.
    Just my tuppence worth

    Not for my Seal but she would be easy to retrofit.

    Another winter project, just testing drivetrain

    "Babyhood" Wondered about that!๐Ÿ˜ฎ
    Thought maybe you might have got 'em as a freeby with a months supply of Pampers๐Ÿ˜‚๐Ÿคฃ
    After several such 'curious' substitutions I learned to switch off the Auto Correction of the spell checker. Now it just underlines in red anything it doesn't recognise.
    Then I can check it and correct or educate the spell checker by adding to the dictionary.๐Ÿ˜Š
    BTW: are these couplings for your Seal or have you got something else on the boil?
    Cheers, Doug ๐Ÿ˜Ž

    Thanks Doug. Have already got them. Somewhat different as they clamp directly onto the shaft and there is a thin slit scroll to provide the flexibility. The input & output shafts can be different sizes
    Will install during the winter refit.
    Look good,got them from Babyhood.

    Hi Rowen,
    Here's the link to the Krick version that I use.
    Only German I'm afraid (despite selecting English๐Ÿ™„), but I think you can see that they are available for a variety of motor and prop shaft sizes๐Ÿ‘ They usually deliver to me within 3 days and they quote approx 7 days for overseas๐Ÿ‘
    Cheers, Doug ๐Ÿ˜Ž

    Go for it Rowen๐Ÿ‘
    Or buy the Krick version. Delivery might be quicker than from our Chinese 'friends'!!
    I'm very happy with them and am in the process of swapping all my ancient UJ/Kardan couplings for this type. Had absolutely no problems running my Sea Scout with a Propdrive 2830 brushless, 30mm 3 blade prop on a 3S LiPo. And it's nice and quiet๐Ÿ˜Š

    Thanks Doug, that is reassuring. These are in aluminum - do not know what grade and they come from the Orient.
    Going to be a struggle to get in but as the alignment is quite good should be worth the effort. The current Hookes joint style couplings
    are noisy
