    Anyone know where I can find the gap measurements for a Yamaha 50 2 stk?

    Thanks NGKs should come pre gapped. Got bad advice today.

    All the rest get checked before installation, every time.
    Too much work goes into tuning an outboard. Not going to
    worry about a couple seconds to ensure I don't have a problem
    rather than wasting more time, later, to figure out what I did wrong.
