Could performance afected by improper painting of transducer? If so can the paint be stripped or do your have to replace it?
Thanks cc

Capt,

It definetly affects performance! You never want any paint on a transducer. I would attempt to remove the paint before I purchased a new one. I would probably start with some laquer thinner and see if that wouldnt cut it.

A thin coat of paint shouldn't affect it. After all, if done properly a transducer can also be installed on the inside of a solid fiberglass hull. The usual loss only comes at the maximum depth range, which hardly matters. On the other hand, it also allows the transducer to operate at any speed because there is no signal loss due to turbulence

That is why when barnacles attach to the transducer you can experience two problems. The first is the loss of signal strength and the second is the increased turbulence from the barnacles.

I do not believe there is much difference between so-called transducer paint and regular antifoulant. A thin swipe of paint will not matter. Too much is a different story, however.

If you want to remove old paint or crusty scale try sanding the transducer with 220 grit wet or dry paper. My boat is in saltwater and I wipe the transducer clean with a brush once a week.
