Have a 04 42 Lightning, full stagger 525's, that I just put 2" Sport Master shorties on. Trying out 6 Blade 31P Herrings right now. Get out of the hole fairly easy with little blow out but can only get about 4800 - 4900 RPM at 76 mph. Any suggestions what other props I should try? Thinking about some Hydromotive H6.

Thanks.
