Re: propulse
OK, made it back with all 4 blades, They will need adjusting to get a little more rpm but other than that, pretty much the same as the stainless 3 blade. Down here in the lower laguna madre. the average water depth is a out 2 or 3 foot. So your hole shot usually involves digging the prop into the sandy bottom. That was the only thing I was really concerned with but the propulse got with the program. It now has a few dings on the leading edge but so does the stainless. I was using a 115 johnson on a 1400 lb 19 ft boat with 500 lb load. So far so good.
