Hi,
We have a 2005 44' with QSM-11's rated @ 660HP. We usually cruise it around 1600 RPM burn 32 GPH and see about 18-21 knots depending on tide, fuel load, trims tabs, etc. I did take a little off my props as the 'dry exhaust' on the QSM is not the best design, I have already had to replace exhaust manifold gaskets at 850 hours. Next time I pull the props I will take off a little more pitch off to get GPH numbers lower. Tony Athens has a wealth of information about the QSM's on his website This is our 10th season with the 44, enjoy your boat!!
