The one MAJOR draw back of this kit, is not being able to adjust tail weight. For long-tail mud motor kits, that is what makes the kit. It is the difference between wanting to go back out on the boat or selling your whole rig because you hate how it rides. This kit is not balanced for speed. Once you go over 11-12 mph, the prop wants to jump out the wake. It does this, because it doesn’t have enough tail weight to keep the prop in the water. The other kits, Swamp Runner and Beaver Dam, allow you to adjust your tail weight. If you want speed, maybe you favor more tail weight. If you do more idling and maneuvering through obstacles, you may favor less tail weight. This Mud Skipper kit does not allow you to do that.
