Maristar losing shuddering and losing power over 2500 RPM

Hey everyone, had an issue over the weekend that I need some help in diagnosing. On Saturday, the boat was fine and didn't show any signs of a problem to come. On Monday, though, anytime you exceeded around 2300-2500 RPM you'd feel a shudder and loss of power. When advancing the throttle in neutral, however, you could go past 3000 RPM like there was no problem at all. Oil pressure is good, temperature is good, no check engine light or alarm, looked at the prop & shaft and they look fine, and starting/idling around was no problem. Does this sound familiar to anyone?

Thanks for any input. Boat is a 1999 Maristar 230 VRS w/ 5.7 Indmar Vortec MX Plus with Hurth 1:1

Woo! That's what I had diagnosed before we pulled out for the day, just wanted to make sure. Any suggestions on a pump? I think I read Delco somewhere on here, but is there a list of pumps that fit our boat?
