2004 Honda 225

I got a 2004 Honda 225 last summer with only 160 hours on it. I've spent the last year dealing with constant fuel issues and unfortunately have barely been able to enjoy it. New fuel lines, cleaned the tank and fuel, new spark plugs, injectors, you name it. I picked up my boat from the shop and there's a NEW problem. Engine starts up fine. Idles great. Seems like it wants to make me a happy boater. However, once I give it some gas and try and get on a plain, it chokes as if it's not getting enough fuel between 2000 and 2500 RPM. It won't take off. Kind of as if it's not getting enough fuel. The engine seems to be fine. I THINK/HOPE my fuel issues should be resolved. Could this have something to do with the throttle?
 
Thanks Captain. That's actually exactly what it sounds/feels like, but the darn filters are new! But I did just have a bunch of water in the tank that had to be removed. I'm sure some gunk could have found it's way into the new filter. I'll check.
 
When is the last time you changed out your external Racor fuel/water seperator? They do get clogged up and would cause the problem you are describing. You should have put in a new Racor after the tank was drained and cleaned. If that is not the problem, put the boat in the water, start it up, bring it up to the rpm's where it gives you problems and check these things...

1. Does your fuel pump-up bulb partially collapse? If so, you have a blocked air vent to your fuel tank, or a blocked pick up tube. Open the fuel tank cap, if that fixes the problem, then you need to clean out the clogged air vent. If that does not fix the problem, you will need to remove the pick-up tube from your fuel tank and check the end for blockage. Blow compressed air back through it to clear any obstructions.

2. Is pump up bulb squishy? (It should normally be fairly firm when you squeeze it.) If so, pump it and see if that helps. If so, then you have a bad low pressure fuel pump or air in your fuel line.

3. Remove the engine cover and look at your low pressure fuel filter. It should be nearly full while engine is running. If not, you have an obstruction in your fuel line between the pump up bulb and the filter, OR you are sucking air into your fuel line. Check all connections, especially around your Racor filter. You may need to fabricate a clear plastic fuel line between the LP filter and the LP fuel pump to see if there are any air bubbles while engine is running.

4. Drain your VST.

Come back at us if none of this fixes or isolates the problem.
 
I had the same problem with my BF2002 225 during the 2011 season. I spent most of that summer replacing LP/HP/Racor filters, fuel line, fuel bulbs, running seafoam through the engine, etc. My problem was that the VST screen was clogged. Once the VST was removed and cleaned, the problem was gone and its been running fine since.
