i changed the spark plugs on my 1999 115 yami.(non oil-injected). the new plugs were supposed to be less likely to interfere with radio frequencies. same number, just had an "r" in there (i believe). anyway, it started right up in the driveway with the muffs on. three days later i go to the lake and it wouldn't start. the motor turned over and battery was strong. it did eventually turn over ( after about 6 minutes of continuos atempts) and ran fine the rest of the day. started with no more probs. it has never taken that long to turn over with the other plugs, but the new ones came from a yamaha dealer and were in the application guide for my motor. so, what's up with that?
<br />Personally, I release mine into lake Crisco
