Spinning the shaft while in neutral is supposedly knot good for
the tranny.

Would think it easier, cheaper and safer to dive once in a while
then your scheme.

Around here, I have to dive and clean my prop at least 4 times
a year
due to fast fouling. If I didnt use her much I'd have to do it
more.
Like many other people I have noticed the fact that boats that
are used
more have cleaner props.
So...........I propose a device which simply spins your prop
several
times a week to minimize fouling. It'd be something like a
small motor
driving a belt going around the shaft. You'd have to leave her
in
neutral for this to work. Something like 30 secs of prop
spinning
every other day might really reduce fouling.
