Mercury racing 700 sci limiters are 5450 rpm. There is a lot you can do to the 700 and 850 and the 1075 engines if you can get into the box and pulley changes.

There might be more there than meets the eye, but, the 700 NXT engine makes 785 hp at the crank and MERCURY also told me that they have 720 at the propeller shaft with this package.
So, I think everyone's base line is off here. 800 is low.
