50hp outboard wont run under load

[Skyna]

I have a E50TLESR outboard that starts fine but when I throddle up the engine dies, I brought it home and put on earmuffs and it didnt miss a beat, this only started to happen after an earlier trip when I didnt open breather on tote tank hench the tank had sucked itself in quite bad, could this have anything to do with problem??, Any help or thoughts would be much appreciated, Cheers

you probably damaged your fuel pump. get a fuel pump rebuild kit.

Cheers, I thought this maybe the case because this only happened on the trip after I forgot breather, before that motor went fine, thanks again

Before you run out and buy a fuel pump, check for a sticking timer base. If the timing doesn't advance before the carbs open, it will stumble or stall. Just a coincidence and has nothing at all to do with the fuel / tank / vent / pump.

sorry to sound dumd but how do I check timing base?? Cheers

Shift into forward gear (not running). You may have to twirl the prop to shift. Then disconnect the throttle cable at the motor. Then with your fingers, move the lever where the cable was attached. That will move a tall vertical lever that moves the timer base. As you do that, you will see just a bit of movement of the carburetor's throttle shafts, while the timer base will be going all the way to full advance. Only after it has reached full advance should the carbs shafts open fully. If they open before full advance, it will stumble or conk out.

EDIT: On second thought, I guess you don't have to shift it into forward gear on that one.
