Re:K&B Auto-trim unit
Propjockey,
Well, "work" is an interesting term when it comes to model boats. It will make the boat go in a forward direction. You are dealing with model tunnel hull technology that is over two decades old. But, what the heck. Sounds like you got the hull at a good price and if you enjoy running this boat you can always upgrade to a better boat and motor. Use an Octura X440 prop. The aluminum prop that came stock with that series K&B was useless. Set the balance point at 1/3 the distance from the transom to the bow - a 24" boat should balance between 8" - 9" from the transom. It's been a while since I taught math, but I think 1/3 of 24 is somewhere around 8.
Good luck,
Jerry
