Re: Sailing while A-4 is in gear

I think it also has to do with lubrication. I believe the transmissions on Yanmar has the lubrication pump moved by the same shaft as the output shaft, while many other lubrication pumps are moved by the input shaft, therefore if shaft rotates from water passing the prop (and motor not running) the gears and clutch plates will run dry. This is more of an issue then the wear and tear of the movement. Also why many boats have a shaft lock, stops the movement of the shaft, normally lined up to keel to provide the least resistance.
