20' cc with 150 Yamaha- ? mph

I have an '86 20' cc with a 150 Yamaha, fuel injected 2 stroke, it runs 40 mph with just me and full fuel, seems as tho it ought to do a bit better, running a 14x17 prop now.
Tach has quit, I think it was turning around 5500 rpm. Anyone do lots better with a similar setup ?
