When I redid mine 2 years ago I used West epoxy-coated marine ply as backing plates. The thinking was easier to shape to the interior hull and the old ones had lasted 15+ years anyway. Also I couldn’t find G10 sheet locally at anything close to a reasonable price. However we replaced the old wood fairing block for the transducer with one fashioned out of epoxy using a plastic food tub as a mold.

I met the yard mechanic at the boat as I figured it would be good to have a second person around for this job. Well, after 4 days the backing wood had expanded enough to stop the leak. So we both decided it was best to leave well enough alone and just keep an eye on it. Assuming it behaves for the summer, this will be my first job upon haul-out. Boat ownership is a bit masochistic...I've only been in the water 4 days and already I have haul-out jobs planned! Thanks for the suggestions...i may have to follow-up with them before the end of the season anyway. Mike Atacama. 33 mkii Toronto Sent wirelessly from my BlackBerry device on the Bell network.
