Help!

Got 130 hp yahama outboard that I'm having to prime bulb to get to start after I shut engine off. Only will idle for minute and stalls and when I get going.... runs rough until I get to around 4000 RPM. I'm baffled and need boat running correctly. Any info to were I need to start would wonderful!!

If the bulb has any age on it or is a non-OEM bulb, try replacing it.

Sounds like you're getting air in the line somewhere. Could be the tank fitting, hose, bulb, or the motor fitting.

Or anti siphon valve letting fuel run back to tank

Could be any of all the above posts.

Really appreciate the info fellers! I took tank fitting and complete hose and bulb off and took to local mechanic and was told it was universal hose bulb and hose on..... (just bought boat 2 weeks ago so don't be on me to hard)replaced with name brand and correct lines and bulb also tank fitting was 1/4 fitting and universal was 5/16 so replace that..... hope that helps and can get back to the crappie! Blacky's move in and time is very precious right now....
