It wears out the transmission because it will force the shaft to rotate,
and it also voids a Yanmar warranty (like any of us have one).

The growth on my prop in the Bay will cause vibration and has made it
difficult to fold on its own even though I clean it every week.

Joel,
I was always taught that putting it in reverse after ensuring the shaft was
in the proper position essentially locked the shaft in that position and
ensured the blades remained where you wanted them. The idea is that

Didn't realize you were putting it in reverse, but as I said, it is less of
an issue with a folding prop because there should be no drag and no twist.

So, if the shaft does not get locked in a position with the folded
blades vertically aligned (the proper orientation) it's possible for
the lower blade to "droop" and create some drag in low hull speed
conditions. Worst case would have the shaft locked with the blades
aligned horizontally.
However,

For years the official Yanmar recommendation was to put the gear in reverse or
neutral but never forward. Only recently (2008) did they change their policy.
These earlier engines had a Hurth transmission. Once Yanmar changed
transmissions to Kanzaki and other non-Hurth gear boxes, they now re
