Who makes good 5 bladed props without a second mortgage on the house. Spent the jack having my 30's labbed but really didn't see anything. or maybe I need to try someone else on the labwork.

Yes, but there are other ways of reducing slip. I'm not saying it won't work for sure, it's deffinetly worth trying, as I said before. But it's on rare occasions that 5 blades give a speed increase on a setup like yours. I just can't get my head around the fact that the slip on that hull with B1 props can't be brought down. I know Bblades has labbed your prop, but have you talked to Brett about what else could be done. It might only need a little cupping. I think the hydro QIV and QIV-X could be interesting to try. Have you ever tried a set of non-labbed B1's in 30" and 32"? Then there is the last thing to try. Your friend has a set of 28's. You are both spinning the same rpm's and going equally fast. Try hes props as well. Something is apperantly working for him with the stock 28's.

What gets me is when I put my back up bravo-1 28's on I run about the same just higher RPM,,Thought about having those labbed and adjusted up.. but hate to dump the bucks in it and not do anything..Just getting my slip down to 13% would be great could put me at 75-76

Nose cones will smooth the flow of water to the drives and lower the slip a few percent. However, lowering your rpm's may slow the boat down. Hard to tell without trying.
