Hi Squarehead, I concur with
Morgan 3820. I have the same unit being installed on my foredeck, I have put it on and off several times for fitting. The motor is easily removed with four short bolts(when new anyways) which gets rid of about 65# leaving you with removing the nuts under the deck that hold the capstan etc to the underdeck
gearbox. The four long bolts are captive into the capstan casting, then you can
lift the unit off the deck. Mine weighs 75 kgs with the motor being a little under half.
cheers, Greg
