[Public-List] Launching 148

[Roger L. Kingsland]

Rick,

Good point, well stated; I never considered reverse.  Vise Grips go back
into the tool box, replaced by a clamp or two.

Best,

Roger "Pi" (so much easier than lerning to spel intensions)

Roger, 

That will make an entertaining chapter the your memoirs, no doubt!

That slipped shaft/rudder jam scenario is why I drilled dimples in the shaft
for the safety-wired setscrews and have a worm-drive hose clamp permanently
installed on the shaft just in front of the stuffing box. The shaft/coupling
joint seems to be the weakest point in the system transmitting reverse
thrust loading to the hull. And no situation, much less one bad enough to
require backing down hard, will be much improved by having the shaft part
ways with the rest of the boat.

I'm curious about what measures or precautions others have used.
