Hello;<br />I was out fishing when my engine overheated and shut down (I am sure the water ports are plugged or impellor is bad) I have not replace the impeller yet, but my engine should still start shouldn't it? It doesn't. I have hooked up the muffs and cranked it over but all I get is a weak firing of the cylinders but no complete ignition. Some of the wires that come off of the powerpak were melted so I replaced that. Where should I start? Thank you!<br /><br />
