2003 Yamaha 225 four stroke...replaced primer bulb...nope...by-passed fuel management valve...nope.....by-passed water seperator....still runs about 4-5 mins and quits...any ideas?
thanks

whats a fuel management valve?
and by bypassing a filter you can make a 200 dollar repair into a 700 dollar repair.
what RPM does this issue occur?

runs and dies

just by-pass shortly to test filter...it happens at idle around 8,000

I am going on a limb.
I am going to assume 8,000 RPM is a typo and you ment 800.
will it stay running ok above 1200 RPM?
