Hi, I have an Evinrude Ocean Pro V6 225 (96 or 97, im not sure right now) and I am having the following problem. The engine turns on and stays on idle completely normal but when you accelerate the engine stops. When its stops its sounds as if the carburators have flooded the engine. The tricky part is it only does it when you accelerate it with a gear on, when you use the other throttle (the one that keeps the engine in neutral)it revs up completely normal. I've rarely been able of making the boat move but when i get it into high rpms with the gear on the engine works completely well. The problem is only when advancing at low rpms.it stops! So I got mechanic to inspect the engine. The first thing he did was clean and calibrate all the carburators. The problem persisted. Then he checked the power pack and it was ok. Then he showed me that my Stator for low RPM's was leaking a black goo. He told me that my Stator wasn't working properly so it didn't generate sufficient electricity to ignite the fuel in the cylinders. This supposenly floods the engine and makes it turn off. I also saw that the outer magnets on the flywheel were a little out of place. I've been wondering if anyone has ever had this problem before? Can my problem be generated by another electrical problem?
*The engine is cooling ok

On your remote control, look for two wires (usually yellow with a tracer)and a switch. Some/most controls have a neutral safety switch so you cannot start the boat in gear. The switch gets sticky sometimes.
You can disconnect the wires from the switch, connect them together and see if the problem persists. Or check the switch with a meter to make sure the switch is ok.

Not really sure the technical term, but the motor has an idle interrupter when you shift from neutral to forward. The hesitation only happens a split second and keeps the gears from grinding. Not sure if that has malfunctioned or not. Also try disconnecting the neutral start switch and connect it to itself and see if that stops it. The neutral start switch must stay connected for the motor to not die. I had a short in mine (Evinrude 225) and disconnected it and connected the two wires together. I have since left them permanently connected and do no use the neutral start switch. Nothing is worse than that switch going out on the water motor not trying to start and having to bypass it, which I have done.

Meant to say The neutral start “WIRES” must stay connected for the motor to not die.

Thanks to everyone for their reply's. The thing with the engine is that you can put the gear on and the boat moves slowly. Then when you try to accelerate it more and the engine reaches about 2000rpm it starts to flood. If you maintain the throttle at this position the engine slowly dies but if you quickly get it back to idle it stays on. The engine below 2000rpm works well and above 3000 rpm works well. It only has problems in this gap when it has the gear on. The mechanic checked the magnets and they were ok. We also checked the remote control and it was in perfect conditions. I know it is an electrical problem and I am quite sure it is in the engine. What can it be?

g lister, I believe you are running out of fuel, not flooding the engine. Try a separate tank, and if it still stumbles, you need new fuel pumps. High Sierra

g lister, one other thing is perhaps the main jets are partially plugged. (Tough doing this long distance). High Sierra

Diagnosing engine running problems is really not a SMALL BOAT ELECTRICAL discussion. This will move to REPAIRS/MODS and join all the other engine-runs-poorly type discussions there.
