I have a 2010 Alpha 211 and I'm going to order a new trolling motor and was wondering what the bow height of an Alpha 211 is? I would just measure it but my boat is in the shop getting some repairs. Anyone know what the distance between the bow and the water is? The manufacturer suggests that the trolling motor sit 12" below the water to avoid cavitation. I just can't figure out if I should get the 45" or the 52" shaft.
