[QUOTE=HiPerf2000]What size 5 blades did you go with ? and what size bravo's did you have ? I'm trying to figure out what the pitch difference is when you go to a 5 blade.[/QUOTE


I was running 4 blade 30 pitch Bravo 1's prior to the Hydrmotive 5 blades which are 27 pitch.

regarding the back filling the motors without the plates, the 496 HO's only take in the water through the exhaust system to cool down the heat exhanger since they are closed coolant systems anyway....so I don't understand how they can really hurt the motros anyway? but I'll ask my mechanis again.
