    Hi

    I have bought a Najad 343 and want to get an autoprop, but I need to need to know the dimensions of the locking nut for the prop.

    The shaft is a standard 30mm but i need to know if Najad was using an M20 or a 3/4″ nut.

    Najad has changed to the metric but I don’t know when

    I want to avoid lifting the boat twice once measuring and once changing the prop.

    it is hull number 76 Najad 343 from 1983. with the MD 17 D engine.

    If any knows when Najad changed to Metric or if any has a similar N343 and knows witch shaft it was launched with.
