2019 mercury 115 pro xs starts runs rough and dies

[rgoben]

I just bought a used 2019 pontoon with a mercury 115 pro XS motor with 14 hours and after a week of running great now when it starts it runs rough and dies. I added sea foam to the gas and loosen the gas cap and still same issue. thinking of changing fuel filter next. Help!

Got to be fuel or poor electrical contact or similar.
change the pre filter water separating filter. The in line small one under hood and also worth checking the one on the fuel rail if the previously mentioned doesn’t do it. But they should be good until about 300 hours usually.
take a sample of the fuel out the filter when you change it and have a look at it. Mine has an alarm for water on it, so should yours I’d think.
