Unfortunately I've got no extra room in the head to floor mount the 'ducer. Barely enough room to drop a deuce! Finding an area to mount this that is somewhat protected while still allowing me access is proving difficult.
Will keep looking around as I finish my work in the boatyard. Could easily drill this puppy and be done with it, but why add ANOTHER thru-hull, ya know? I've already got 7 (engine intake, septic outfall, raw water in & sink for kitchen & head, water speed 'ducer). Assuming that's typical (???).
