    Hello All,

    It's been a while since I've posted anything. I've got an issue with my Mercury 25 hp 2 stroke. It will idle fine, but when I put it under a load, it will run for a few seconds and then die. I'm changing spark plugs and fuel filter. Anything else I should be looking at? Thanks!

    Sounds like a fuel issue. I had a clogged fuel filter that would do the same thing. Also check your fuel pump. While manually pumping the primer bulb see if it takes off.

    That's kind of what I was thinking. I'll give it try. Thanks!

    I don't think so. I put new ethanol resistant lines on last year, but I will certainly check it out. Thank you Sir!
