Sounds like you are checking the bulb after it dies. Do you know if it is
collapsing before that point? If it is, you have a vent problem on your fuel tank.

Other common problems are fuel filter clogs and gummed up carbs.

One of the worst things could be your stator. I have heard of more than a few
that heat up and stop producing electricity - particularly at high speed and
after a bit of time. BIG bucks so I hope that's not it!

Hey all,

I have a 1993 Yamaha Pro V 150 on a Ranger 354v Bassboat. When I put it all
the way down, I start going really good, then it starts to sputter and the
RPMs drop in half. If I go back and pump the ball full of fuel, I can once
again start going without problems. I am wondering what the possible
problems were.
I just had it in , and they removed a electric Primer pump that was wired
incorrectly. They told me that the vaccum from the motor is fine (no
restrictions) . So I am not sure what the hell it can be, and thought I
would post it here and get some opinions, of things to look at.

Thanks again,

Chris
