Anodes

The Ambassador should be Ok

ITYWF that its Delrin bearing will preserve the electrical isolation of the propeller.

Sorry to dispute that one Vic, but I have now got cutter & prop in my shed. I can assure you that the cutter connects the prop straight to the shaft. The part of the cutter that sits in the bearing is the single blade part that connects to the saildrive vertical & has the pin that goes through the saildrive anode. However, the double blade part connects to, & rotates with, the prop. That part sits on the sleeve that slides on the saildrive shaft.

That is bad. If the electrical isolation of the prop is bridged by the cutter then the life of the saildrive anode will be seriously reduced. Then, if that is not replaced, the saildrive leg will be at risk,

The modifications you suggested earlier seem like very good ideas. If I understand you correctly perhaps all that is necessary is for the sleeve you mention above to be electrically insulating,
