    Boat motor advice

    I have an 30 hp 3 cyl outboard motor..Yamaha, of course.. that I'd like to try tuning up myself without going to the dealer. It runs ok at speed but shudders and chatters off idle until about half throttle. Does anybody know of a good website or forum for this? Can't seem to find one.

        Evinrude/Johnson has a product called engine tuner. When I soak carbs I use this product and it works very well. It's for both 2 and 4 cycle engines.
