Thanks Texasmark
I know the props are easily available. It is the rubber hubs I was inquiring/enquiring about. I have a good prop with a spun hub. I was under the impression they are pressed in, but Scott above has corrected me.
I shall update once I find out how possible it is to get the prop refurbished.
Incidentally, it seems that the DPO used a glue to attempt sn amateur repair, or maybe just to sell the boat. Caveat emptor I guess.
Back in the '50s for a period, You had Mercury and OMC. Mercury used a splined prop shaft/prop interfacing pressed in, rubber slip hub (had one of those) that would allot the prop to hit an object, break loose from the prop casting proper and upon the operator reducing the RPMs to idle, or shifting into N and back to F, the hub would reseat, allowing the operator to be on his/her way....very desirable when fishing the windward side of rip rap (where the fish are).
OMC (which I also had) had a pressed in, rubber hub with a "drive" pin connection to the prop shaft. When fishing the above hazardous environment, if you accidentally hit a rock the "drive" pin would no longer drive, but "shear", hence the name we gave them...."shear pins". I guarantee you this design would leave you in "harms way" big time. The rubber hub may or may not have slipped in the process...I don't know.
I do know that on lower hp engines brass was the material for that pin and would shear. Dad's engine was a 10 hp Scott Attwater and on the tiller handle was an OEM installed, rubber gadget containing 2 cotter pins for the prop nut and 2 shear pins for the prop shaft......what does that tell you?
I do recall instances where I learned/saw that the brass was replaced with SS so as to remain a drive pin, and not shear.....maybe for the larger engines, like the Fat 50. Well in that instance the hub would have to slip and reseat like the Mercury hub to accomplish the desired engine damage saving function.
