I have a battleship with it on there...Champion 206...73.6 at 5770 just me tourney loaded..up to 69 with my xl partner...These are approaching the fastest logged speeds on the Champion forum for this boat, and that is in high August TX humidity and HIGH temps...This boat feels so light with this thing pushing it...It did take a few days for me to tweak the height to the best balance of solo vs partner...I don't run that fast alone usually, and I wanted the best top end with a heavy boat, so I went for that. I could likely get 75 out of it if I raised it a little...heck, cooler weather may do it anyway... If you know the 206, it is a stable rough water boat that drives great...Now it is better with this motor...Fury 25p stock, 10 inch slidemaster, 25.5 setback, numbers provided by mercmonitor...I will play with props when I get a little more rash on this one...
