OK, gents, thanks! I will keep you posted. And granted, the
part may not be critical, but the
function of stabilizing the propeller dome is. As I said, the idea of using tape (which another resident here is also doing on his RV BTW) or even old tire tube is pretty darn clever.
However, an elegant part designed for the purpose and that is not horribly expensive is kind of appealing, too!
