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



Will the engine run on a portable fuel tank? If it does you have ruled out
the engine as the problem. If it won't, you have ruled out the boats tank
and associated fuel system.
