When I was in Turkey I fitted a new prop shaft to my boat, because the old one was pretty pitted. I had noted some tendency beforehand for the shaft to turn very slowly whilst the gearbox was in neutral but had not thought much of it. On installing the new shaft I spent a long time carefully correcting the previous misalignment.
When the boat was launched I had to Mediterranean moor it between two boats. Reversed in, put it in neutral, quick short burst of revs in forward to bring the boat to a stop. So far so good. Put it back in neutral with the boat stopped at passerelle distance from the pontoon. Went to throw the mooring lines and found the boat happily picking up speed and motoring out of the berth. NO NEUTRAL! I did get it moored and on investigation found that the gear selector plate in the gearbox is worn, so that it does not stay fully in neutral but allows the forward gear clutch to drag. With the prop shaft now correctly aligned and much less friction than before the forward clutch does not slip. It turned docking the boat into a spectator sport as I juggled between reverse and going forward in neutral in an effort to hold the boat in one place whilst the lines were secured.
Gearbox is now out for a new selector plate to be fitted.
