The 24V only shows being offered up to 72" where the 36V is 84" and 96". Their formula to figure shaft length is (Bow Height”) + 18” +(Wave Height”/2) = (Shaft Length”). Thinking out loud here; If I use 40" for bow height and 36" (probably not happening) for wave height, I get 76". Using 24" wave height I get 70". I would imagine the 24V is cutting it close as they're not effective out of the water.
Does anyone here have one on a 20' SF?
