    Yamaha 115 4 stroke sputter/stalling. Help!

    Thanks for your help man! I ordered a new IAC and will update after that. I also will check the oil for any gas in it. My fuel pressure regulator is pretty rusty too, so thinking I am going to replace that as well

    Yamaha 115 4 stroke sputter/stalling. Help!

But last time it was in the water, I plowed back to the marina around 2-2500 rpm And it did not stall or shudder. It was only a quick ride though, about 2 football fields. Right when...

    Yamaha 115 4 stroke sputter/stalling. Help!

    Ok so update. Replaced injectors and spark plugs. Put fuel pressure gauges on fuel rail and read 37 psi when running.

    Yamaha 115 4 stroke sputter/stalling. Help!

    Yep, above 2k and yep above 2k all was ok. Once I pulled back, it sputtered and then stalled. I am definitely checking fuel pressure at fuel rail and after low pressure pump

    Yeah I tried pumping bulb when it was sputtering/before it died and nothing changed. Starting to wonder if it’s my idle air control valve. Going to the marina today to take a look

    Yamaha 115 4 stroke sputter/stalling. Help!

    No fuel additives. Ethanol free. Water separator changed and fuel filters. If water was in gas wouldn’t it run like crap all the time? Not just below 2k rpm?

    Yamaha 115 4 stroke sputter/stalling. Help!

    Yep printer bulb is firm and did not help the issue when it was bogging down. I replaced plugs last year but will check them for sure. I did replace the coil packs 200 hours ago so they are new. The filters are all full. I start with plugs and then test pressure and confirm I am at 40psi at the...

    Helm seat upgrade - 180 Sportsman

    I am talking about sitting higher. The oem one is so low..can’t see over the center console without standing. Nothing to do with trimming or anything. Looks like Stryker makes some higher up

    I just asked him. I do know it has a 25 inch shaft like my current one. It also looks identical and isn’t a SHO or anything.
