Honda 225 surging at mid range RPMS

I have a honda 2005 225. The motor is having a problem at mid range rpm's i get to like 2,000 rpms and then it starts to surge (seems to be starving for fuel) I took and inspected the filter by the oil dipstick, it seemed ok. I then took and inspected the High pressure fuel pump at the rear of the engine i removed the cowling and everything else in the way to get to it. I replaced the filter (old filter was collapsed) put everything back together and then put the boat in the ramp and then i had a leak with fuel in the water. (long story short pinched the O ring on pump and now replaced it) Put the boat back in and then off i went and the boat ran perfect for about 200 yards on top and then started to surge again. I have a brand new racor filter and also pulling out off a plastic above deck tank. Please help as i am out of ideas. Thanks Jordan
