Does anyone use one and do they work? My backside is a little bigger than average and I have a 14' V-bottom jon boat with a 20hp longshaft outboard on the back. With my backside and all the weight of the motor and 2 batteries the bow comes WAY up when I'm heading down the lake by myself. I've looked at the hydrofoils (Doel-fin and Stingray) that claim to keep the bow down and wondered -- Do they work? They run $40-$50 and I'll have to drill holes in the motor to mount it. If they're not really worth it I don't want to drill a bunch of holes in my motor for nothing! Thanks!
