Are you sure that's not 18 HP? Specs I looked at have the 2GM getting 3 
more HP than the 2QM (which they did by increasing RPMs). Maybe GM and 
QM are lines of engines-with a range of HP, but your 3 blade is moving 
considerably more water than my 13X12 2 blade, which I judge to be just 
right on my 2QM15.
