Shaft protection

[cimo]

yep, although in my previous post, I meant isolating the tapered/keyed shaft to prop interface (to break the circuit as you say), allowing me to dispense with the shaft anode altogether. its the only anode I have now that requires replacing. One more maintenace task permanently removed from the list would be the objective!

............. it is not so easy to isolate a prop that is on a taper to provide the drive.

exactly. here's the challenge.

If it was desirable and possible somebody would have done it by now! After all the "problem" (which is not really a big problem) has been there for years! The incentive for a saildrive is rather different as the rubber bush is required to reduce shock loadings on the gear train as well as the benefit of isolating the prop.
