I hadn't had my boat very long maybe a month. I have found a little problem. I don't know what it is but when I am running Trimmed up or down wide open or half throttle the engine is jumping feeling like it is about to lock up but I know that is not it. It cranks up fine and idles fine just when I start going it goes but hesitates a little bit. If this sounds like anything anyone could help me with please let me know. waaaaa bump waaaa bump waaa bump waaaaa! It kinda jerks you a little bit and you can definetly feel it.
