No get up and go… engine stalls

[boneil]

Background:  Boat has a full tank of gas and has been in storage for last two years.  Last tank was Chevron but not 100% sure ethanol free. 
Boat goes into gear and I can motor around slowly just fine.  RPM < 1,000.  If I “gas it” the RPM’s quickly go above 1,000 but do progress.  After a second or two the engine begins to sputter.  I am assuming that the motor is flooding so I do not leave the throttle open I pull back to neutral.  The motor either stops, drops to idle or drops to idle with a brief spike in RPM. 
I don’t help per se, but if some here wants to give me feedback I would gladly take it.  I am planning to syphon some of the gas and check for water, poor the contents of the fuel filter into a jar to check for water, replace fuel filter and replace the plugs.
Searched and found a “limp mode” post.  I will see if I can find the fuel return line, but am worried about potentially popping off or breaking a fuel line.   
“I had the same problem last year. Took months to figure it out. Turned out to be a short at the fuel pump. I'd check those straight away to make sure they work. If they are running you can feel them vibrate when you prime the fuel rails (red botton at the back of the engine. If the boat stalls when trying to go,  clamp off the fuel return line with vice grips (at the fuel pumps) and try it again. If the boat doesn't stall you have a bad pump, loose connection or a short. PM me if you'd like.”

Since it has been sitting that long I would suggest that you drain the gas completely, replace fuel filter, refill with premium fuel and a bottle of injector cleaner, replace spark plugs, clean MAF sensor, spark arrestor and throttle body.

There is not much left after that but to ensure both your fuel pumps are working as you have noted below already.

I have not yet checked my pumps.  I was quoting from a previous post. 

I could have a bad pump!  Anyone know if the boat will start when one of the pumps "goes bad!"  It starts and goes into gear just fine. 

Thanks for the support.

there's a procedure for priming and checking both fuel pumps. I would swap the fuel filter and get new gas in there, pull and clean the plugs, if the thing doesn't start and run fine go through the fuel pump check procedure. I think its stickied. I'm seriously way to lazy to search but you should:)
