Check your outdrive fluid bottle to see if it is low because the ECM will not allow the motor to run over a specific RPM if that is the case. It could be other things like a dirty fuel filter as well.

Since you have a 2002 year boat I am going to assume you have analogue gauges and do not have smartcraft therefore you are not in guardian mode (smartcraft enabled safe mode – limiting power)
So that leaves fuel, air or ignition.
I’m in agreement with Dave about the fuel filters.
Change both the fuel filter (small, round, metal looking in your fuel line) and the fuel water separating fuel filter. These are easy to change and not very expensive.
If it’s not the fuel the next inexpensive thing to check is air. Have you cleaned your flame arrester lately? If not, remove, spray with carb cleaner, wash in soapy water, rinse, dry, let it dry in the sun and reinstall.
If it’s not these two, you are down to ignition. Spark plugs, rotor, cap, auto timing advance could all be at issue.
Start with the fuel filters and flame arrester.
Please post a followup letting us know the result.

Thank You all for the help, I did have someone install a fuel flow sensor which may be the issue I changed out the fuel filter before it hit the water so i dont think thats it I will get over there today and see what I find I will keep you posted

You can't compare RPM's when in neutral vs under load. If you can't exceed 2000 RPM under load then as stated by others it's most likely running fuel starved and has a dirty filter. Is there any backfire from the engine under load?
You say you just splashed it the other day, did you treat the old fuel prior to storage? How?
You might consider adding a can of Sea Foam to the tank and some fresh fuel. If you have the ability to run from a remote 5 gal tank you can try that to eliminate the concern of bad fuel.
Start with the basics, check plugs, cap, rotor, seperator (drain and check fuel)...if those don't address the issue then look deeper, ignition control module, pressure check your electric fuel pump...etc.
Good luck...it's always easy after a few bucks.
Jrock,
Like others here have stated, first start by removing the fuel water seperator. Pour the fuel into a clear jar and let it settle, do you see any signs of water? Replace with a new seperator.
Engine surge and backfire are most likely signs of a fuel starved engine (this will show-up under load, not running in neutral and please let's not run 3,000+ RPM in neutral. not sure if the SeaRay 225 has an anti-siphon valve but if it does that is worth checking.
I had a similar issue with not being able to run over 3,000RPM without backfire and engine surge. I started in steps with each of these followed by a test drive... Fuel water seperator, clean flame arrester, plugs, cap, rotor, wires, pressure checked electric fuel pump (replaced as it was under spec) then finally the ignition control module inside the distributer cap. All with no improvement.
Finally I got it...I had an ignition interrupter switch that was failing intermittently. This switch is designed to momentarily kill the engine so that you can shift out of gear. This switch was changing states (on-off-on-off) but only when hot and only under load..since i've replaced it I have had no issues.
Not saying that this is the case for you, just giving you ideas.
