what would the best wy to fit a transducer into a wooden hull....can a hole be drilled and the transducer epoxied in situ...or woudls a through hull transducer give acceptable results
A through-hull transducer won't work in wood - you'll have to get your drill out! It's generally agreed that a bronze one is required for wood to resist plank expansion, but several (me included) have an over-sized hole, a plastic transducer, and a good sealant bed.

Quick additional edit... reading your post again, epoxy is probably a risk as it has no give. You'll need a nice fairing piece and a flexible sealant I think.
its for a friends boat....60 ft pinnace....its one of the garmin type transducers....would it be ok to drill the cable right through and hog out from the outside and bed the transducer in with the sealant as you suggested....what would be the best sealant for this job....
Stephen hasn't said what the transducer is to measure; speed or depth? If it is speed, yes a transom mounted transducer is as good as any. If it is depth, it tells you nothing about the conditions being encountered at the sharp end of the boat, where all the action is. In the case of a 60ft boat, these can be markedly different!

I am interested in mounting a log/ speed transducer on the transom. What is the usual arrangement to allow defouling, and how do you avoid the prop wash affecting the readings.
Ok manyh thanks for the response....from what i can tell....it would be best to fashion a blister/eye out of wood and fit the transducer into this with the cable passing through the hull....
I'll have the hole made over size and bed the transducer in sikaflex for tritonofors.....
What is the best wood for underwater use....will it need treating or is primer and several coats of anti-fouling ok
It is indeed a speed/fish finder transducer....originally designed for transome mounting....i installed mine in an existing hole in my steel hull and faired it with epoxy....but i have no idea about wooden boats...I thought it best to check if my experience/knowledge also relates to wood
