The only difference between a 9.9 and 17HP, 65, 75, 85hp is the size of the carburetors given the bore and stroke are same, Carburetors make a big difference on an outboard’s HP, porting no so much because the piston and combustion chamber are goofy so for max hp on many 2t outboards different pistons and heads are needed
