Mega, Boiling water is probably exactly what you were doing. When the prop loses the grip on the water like that there is a severe drop in water pressure on certain areas of the prop, enough to cause the water to actually boil away, possibly causing micro-pitting or other prop damage. This may be why there's not much paint left on that prop you've got. It sounds like you should at least try a four blade. They claim to be better under heavy loads at reducing slip and improving low speed performance. If you're like me you don't give a rat's tookus about top end speed, as long as you can stay in the right cruise zone for good fuel economy. I'm interested in some of the cheaper aluminum four blades. You never know, they may be the ticket (and at a reduced price). I don't think I'm crazy enough to buy one of those adjustable composite four bladers.
