Transducer Antifouling
 

Have a transom mounted transducer, one of those 6-7” guys. It gets pretty fouled ! What do you recommend to paint with, if anything at all, to minimize this without affecting performance ?

I have the same question

I too would like to know the answer to this is someone recommends a product.

I know they sell a spray for transducers and engine brackets, anyone recommend anything? Does it last a season?

Found this online --- From Garmin:

In certain environments, namely salt water, Garmin recommends painting the transducer with a water based, anti-fouling paint.

Anti-fouling paint helps to hinder marine growth and maintain transducer performance. This also helps in boat maintenance by lowering the costs associated with hauling a boat for cleaning.

Garmin recommends only using a water based, anti-fouling paint. Ketone-based paints should never be used. Ketone-based paints can weaken many plastics and possibly damage the transducer.

Please note: Garmin does not recommend painting the paddlewheel portion or any moving parts of a transducer as this can cause restriction.

This stuff works good
