Does the boat seem to even pick up a little if you back off the throttle?

Fuel issue.
Filter or pump.

had same problem-Calibration for throttle

I went thru my whole fuel system cause I was losing power, almost cutting out at high RPMs, but its a throttle calibration issue, and its easy to fix. Contact Eddie with Tige in parts and have him email the updated calibration to your nearest dealer that has a computer setup to check for codes and stuff on the engine. All they do is plug in to your boat, download the new program, it intiates you engine, and then you will be good to go!! It took like 2 mintues for them to download it onto my boat. SO EASY, I was pissed cause I pulled injectors, fuel pumps, and changed filters cause I thought it was a gas issue.
Good luck, hope this works for you!!! It sucks have a boat that can't run, stressful!!

What engine do you have?
On my Marine power I had an issue with the primary fuel pump. (Lose wire)
On skindogg 44 boat, he has throttle by wire. I believe that you do not. (I don’t think Tigé came out with that until 2006.)
Do you have fuel injection or a carburetor? (This will also make a difference on what could be the issue)
