Speaking of weight...I believe my diesel setup is at least 1000lbs heavier than your single outboard.
1350lb Engine dry
100lbs oil, coolant, raw water, hoses et al.
130lbs transmission and jackshaft
My water line is basically where your bottom paint ends. But that being said, it still takes off like a cut cat.
I also noticed that my waterline moved a good couple inches in freshwater compared to salt. If that photo was taken in fresh, you will be even higher in salt.
