Matt,
I saw a guy at the ramp last fall with a v-bottom similiar to mine sporting a big old longtail mud motor and pods. My boat is a 17' deep V. I don't know how big a motor he had but knowing what Dave Larsen has this guy's motor must have been around a 30hp. The pods were welded on at a angle following the V of the hull. The pods were almost totally submerged except for a couple of inches at the transom. The boat was sitting as low as mine. I remember thinking to myself what was the advantage. Maybe it helped plane out the boat. I didn't talk to the guy. You might call Beavertail and ask the question or ask over at Mudmotortalk.com
