The boat won't restart when hot and runs a little chuncky at an idle. I am unable to duplicate problem on the muffs. Compression is good (125 psi) all cylinders. Rebuilt carbs and changed plugs. I brought it to a shop and they told me I need a power pack. They said that if I am changing the power pack I should change the timerbase and stator also. If the timerbase or stator is bad it could wipe out the new power pack. To me it sounds like they are just wanting to throw every electrical compontent at this thing. They want $1300 to repair this. Does this sound right?
