Ok, I've been using up my question cards pretty quickly this week, but try to forgive a guy who's cramming in projects before the snow flies
This time my question is about the shims for the transponders on my hull. It looks like it was made from wood, which doesn't directly concern me. But, it also appears that it wasn't well sealed with epoxy. It's not rotten if I poke it, but it was definitely a little damp. I'd like to leave it in place and improve it rather than starting over.
Here's a picture... There's one on each side (depth, speed).
I'm not happy about the  sealing, and  slight gap between the hull and the shim. Oh yeah, and the blisters I haven't ground out yet!
My question is... How SHOULD this look? Do I just need to sand it down and coat it with unthickened epoxy, then make a fillet to join it to the hull better? Do I need to glass it to the hull? Should I be concerned about it having screwy water flow that messes with the sensor?
I just haven't seen enough of these things to know what to do, and my bible, "This Old Boat" doesn't have the answer for me
Thanks in advance,
