So I am extremely new and
learning lots getting my first sailboat restored and ready for the
water.
This past weekend I installed the prop Shaft with drivesaver and really don't like the fact only 2 set screws keep the shaft from sliding FWD/AFT. I have researched and it seams to be a common problem/possibility that one could be
lost out the rear with a strong reversal and set screw failures.
I was thinking and with the drive saver I can slid the coupler and extra 1/2 inch farther onto the shaft compensating for the drivesaver thickness. On this extra portion of shaft I think I could fit a keyed shaft collar the could resist up to 3,000lb axial force. I can also do the same on the other side encapsulating the coupler as a safe gaurd. Similar to the attached models/pics.
Finally like so many post suggest either put another collar or zinc a little ways away from the stuffing box in case all else fails at least keeping the shaft in the
boat.
This brings me to my question to the community. Does this seem like a good idea? The shaft is
bronze with
steel coupler. What metal type should the collar be? I was thinking black oxide
steel.
Helpful feed back is greatly appreciated
