Can you post an engine pic?

I'd talk to BBLades and see if a set of Maximus props don't get your slip number down. I think that Beerman ran somewhere in the mid and maybe upper 700hp range and he ran 90+ at the shootout.

Also have you dynoed your engines to see what they actually make for power? 800HP seems like a lot for those motors at 5250 RPM. I'm far from an expert so I can only go on my experience and both my chief dyno (before I bough the boat) and Boyd after the rebuilds had my motors making near 700hp in the mid to upper 5000 range.


The only other thing I can think of is mine, Tanners, Randys and I think seahawks are all kevlar boats so there might be a weight difference too.
