82/84mph sound reasonable with that power.

It is a bit confusing with the rated power of the Scorpion engines. According to the "Operation, Maintenance & Warranty Manual" they are 360 crankshaft horsepower / 269 KW. But according to the Service Manual from Mercury Racing they are rated as 350 propshaft horsepower / 261 KW.
But if asked I say they are 377 HP at the crankshaft, even though the owners manual tells me different.
