If you have removable transducers, take them out when the boat is at the dock and clean them once a month at least. If they are not removable, someone will have to go under the boat and clean them.

I do have removable transducers, but I'm a little nervous removing them. Besides I do like to keep a dry bilge and it's a real bear to dry it out when it gets wet.*
I did find this special purpose paint for transducers:*http://www.westmarine.com/webapp/wcs...st%20Popular|0
When I hauled the boat there was no growth on either transducer. I don't know what the PO used if anything. Looks like bottom paint. The speed log didn't work, but I found it not electrically connected so I'm hopeful that it will now work.
I'm going to call Interlux and see what they say. They've been very helpful in the past.
