If you don't antifoul them they will get fouled fairly quickly & potentially cause drag. The difficulty is getting anything to stick to shiny stainless. Hammerite Special metals primer is sometimes recommended or Hempel light primer.
I think a new one is still available but because it's only for a spare I'm waiting a bit longer.
That's a good idea re trying to get the old one rebuilt, but it's quite a small motor & probably 'sealed for life'.
Luckily the existing unit still works, but I need a spare one -which I have apart from the 12v blower motor - this has failed. So I'm trying to source a new motor or complete heater!
