2006 mercury 115 4stroke

[robmayas]

So I just bought a 2006 sv1700 with a merc 115 4 stroke. Ran great yesterday morning and after lunch it was just sputtering. Like clogged filter. When i rev the throttle it sounds great but when i engage it into drive it boggs down and just doesnt getup. Dumped sea foam in lastnight and still running rough. Emptied fuel filter and it was fine. Thoughts? Also fuel been in the thing for over a year...

Year old fuel isn't a good thing especially if it's ethanol fuel since it tends to separate over time but since there was no water in the filter, it's probably not a bad fuel issue. My first guess would be the injectors need cleaning. They could foul and not spray as they should when burning ethanol or old fuel. I'd run it on a portable tank with new fuel before I pulled the injectors just to be sure.
