I'm thinking about ordering a mud motor kit and building a mud motor for at least one of my layout boats. Currently I have a 12' Hunt 'Em Foam layout boat. On the Swamp Runner site they recommend the small and mini kits for layout boats. I would like to go with the small kit and a motor similar to the Predator 212 but I'm concerned about the weight. Some of the places I hunt we have to go over levies so keeping weight down is ideal. Does anyone run the mini kit with a 3.5HP motor on a layout boat and how does that work for you? Thanks.
