WOT i'm burning 23gph and hitting around 44-to-45mph. I'm surprised that a 300hp etc doesn't go right past 50mph.

Me too - might want to look at:
1. the boat - is it water logged and therefore much heavier than spec
2. is the engine too low
3. is it prop'd right, getting max rpm, and trimmed out when testing full speed WOT

Would think it should run the boat to at least 55 mph.
