[blue][size 2]Hey Dan, this time of year my first guess is old gas. Gas has a short shelf life, water can condense in the tank, it can turn to varnish, etc. I use a product called Sea Foam to combat all those problems, though the other product mentioned works similarly. First, I'd drain out all the old gas and fill up the tank with fresh gas and a heavy dose of Sea Foam. If it smokes like crazy, it's not the Sea Foam--it's the crap it's cleaning out of your engine.[/size][/blue]
[blue][size 2]The other thing I do is run 100% synthetic oil. It burns cleaner, doesn't fill the boat with smoke, and keeps your motor clean. After switching to synthetic oil AND running Sea Foam, I had to change my plugs because all the crap cleaned out of my motor fouled them. Now my motors run great. I also always add a little Sea Foam to my gas just as maintenance.[/size][/blue]
[blue][size 2]Good luck.[/size][/blue]
