Currently got my boat on the slips and trying to decide how to best protect the prop shaft from fouling.
I have had it suggested to me to wrap it in electrical tape which is a method I have never heard of before. It's a stainless steel shaft and there is a fair bit of it exposed.
Any advice in the next 48 hours gratefully received.

Electric tape does not sound like a good solution. Firstly, it is not designed to keep fouling off a prop shaft. Secondly, if your prop shaft is stainless steel, it needs oxygen to stop corrosion. SS stays bright because the chrome in it reacts with oxygen to form a very thin oxide layer that protects the iron. Starve it of oxygen, and the seawater will corrode the iron, which is why SS in oxygen-depleted water turns into a pile of rust very quickly. Seawater at the surface (where your boat should be) has enough dissolved oxygen to feed the chrome. The electrical tape could insulate the prop shaft from the oxygen it needs to prevent corrosion.

What’s the concensus on how long Propspeed lasts? Our plastic feathering prop is susceptible to fouling, in that if the blades don’t spin into the correct position the engine won’t deliver revs in reverse. On the other hand, Propspeed costs about the same as a new Windsurfer sail or a nice carbon wheel for the racing bike, and in many ways I’d rather spend the cash on toys like that and just dive in to clean the prop.

Has anyone tried a lick of hard racing antifoul on the prop and shaft? I used to have hard racing on the old boat and I can’t recall the prop and shaft getting dirty before the hull did.
