Yeah I think i'll do that to have them as spares, nothing worse than being
in the middle of nowhere and having a broken down plug

Hi all,

Just recently bought a little runabout with a 1999 15 Johnson. It seems
to
feel like its missing at low speeds but runs fine at higher speeds. I'm
not
experienced with boat engines, but I am with cars and it sounds / feels
like
its trying to fire but not quiet. The plugs (x2) look ok and not fouled.

Any suggestions on where to look first?

Thanks in advance for your help

Replace the spark plugs. They don't have to look fowled on a two stroke.
If this cures it, buy two more. Just because you'll need them when you
least expect it.
