My 1989 150 hp Mercury engine will idle fine & run good at 1/4 throttle, but won't go any faster & won't plane out. It has a hot foot throttle. It has new plugs & plug wires, good compression, a new impeller, new gear oil, all three carbs have been cleaned & a new gas line & bubble. I think it might be the stator, but I need an expert opinion. Thanks.

There are some tests for the stator on the CDIElectronics web site.
