I still don't believe spark plugs fixed my problem. My 4-Tec was running fine when I last had it in the water. The only thing that changed was it sat in a hot garage if Florida for 8 months and when I went to start it, last week it would run for 10 seconds and stop and would not start again. I was thinking plugged fuel filter or worse. The shop wanted $85.00 just to check out the problem and after taking your advice, I fixed the problem with $10.00 worth of spark plugs. Thanks again
