Re: Hurth engagement question
Really, the transmission should come off with the boat in the water.
Disconnect the final drive, take off the flexible coupling, and push the driveshaft aft.
The gearbox should come off then, or someone has overlooked a basic.
The idea of having to lift a boat out of the water, disconnect the prop, drift off the final drive coupling and pull the propshaft out just to get the gearbox off is a monumental design error.
I doubt if anyone has been that stupid.
