Hey Guys,

I'm having issues with this motor since I bought it a few weeks ago,It's been surging and won't go past 3000 RPM and will plane when it wants too:( So far I dumped all the fuel and replace the fuel line and the fuel filter,I also replaced the plugs and replaced one of four coils at the marina.It was getting costly so I had to bring the boat home.After doing all that work it's still doing the same thing,Should I replace the other 3 coils or Am I looking at something else? The motor only has 60HRS on it and I appreciate any help I can get.

Here's an update; I replace the other 3 coils and still running like crap.Does anyone have a diagram where the VST is located on the engine,I'm thinking it's fuel related.The engine is misfiring and backfiring and I hear clicking noises.
