Paint the trim tabs ?

[T.R. Bauer]

I don't think I can recall ever seeing a trim tab that didn't have antifoul paint on it if the rest of the boat had it. I guess I'll have to pay more attention, but I have a hard time thinking of a scenario where you wouldn't want it there too as long as you were in the process of doing it already. And yes, spray on zinc actually does work. However, you have to manage your expectations because the coating will be thinner than it is when you apply it with a good old fashion brush. With that said, the zinc paint has worked great on the galvanized boat trailers I have performed welding repair jobs on....not really the same thing I concede.....You want bottom paint to have some thickness to it in my opinion and spray from a can is hard to do that with.

I have always used a special transducer anti fouling paint on the depth sounder transducers. No problem with the zinc on the motor, if it is well primed or the prior base paint is in good condition. I would not use any antifouling containing copper on the motor bracket or any part of the aluminum.
