[QUOTE="ACarbone624, post: 55868, member: 156"] I have the same sort of problem with mine. I haven't used my boat much in the past 4 months and when I started it up over the weekend it was kinda backfiring/stumbling a little. It was a PITA to get started too. It never did it before so I'm guessing its the ethanol and old gas causing my problem. After it warmed up it ran better but still had the same problem. My plugs still looked good. I changed them this year. I guess I will see in the spring when I fire it up. Over the weekend I fogged it, changed my lower unit lube and put it away for the winter. We have a freeze warning for tonight. The cold weather is coming fast! [/QUOTE]
