Go with the 4 blade first, that is a big jump from a 3-5 blade. I have full staggered engines and handling around the dock is not so great, but with the 5 blade it seems to have a little better manners around the dock. Also the fuel economy seems better, the boat cruises easier at mid to upper rpms. I just installed Smartcraft guages that calculate fuel useage, but I didn't have them with the Bravo 1's.Canada Jeff said:Just for schits and giggles I swaped my 30 labed 4 blade bravo last weekend, to my 26' Labed Hydro five blade. Came out of the whole with alot less slip and less effort. Mid range was alot stronger. I didn't check the top speed (I expect it to be down some) but the rpm was 5100 or so. The difference in handeling at the higher speeds was alot better too.
The down fall to this prop is alot more stress on the drive.
