Not a thru-hull, but I just installed a Shoot-thru and love it!
Initially purchased the thru-hull but it was just too big (and expensive) and wouldn’t fit it the “wet box” area of my skiff given the pumps etc in there.
The Shoot-thru doesn’t work shooting thru foam core. So inside one of my rear hatches I had to cut the inner hull glass, scrape off foam and then reinforce the remaining outter hull glass with 3 layers of glass. Then epoxy the ducer to the reinforced area.
A bit of a project, but the performance is great. Holds bottom up to 28 mph at very shallow depths.
