    Any E in the fuel? How long do you let it sit between running? Do you use any stabilizer?

    Six weeks is rather long and enough time for water to absorb into the fuel with E in it. I would use the stabilizer to help with rust prevention because E in fuel is corrosive plus it keeps the fuel fresher longer. There are several brands out there for outboards so pick. I use Stable and get it at Walmart.

    Did it look like this ethanol-created crap?

    WATER in the gas. NEVR buy gas from a station that doesn't have a boater for an owner. Here in FL we have a lot of this going on. Get a fuel/water separator. This should fix the problem..................

    Is the Yamaha oil injected? If so, the jets are much smaller due to only fuel going through them as the oil is injected behind the intake and they won't let anything thick pass. The OMC has a pre-mix pump in front of the intake and has larger jets.
