I am planning on taking my boat to them tomorrow to have it diagnosed. They are a mercruiser dealer and have the Merc computer stuff. What concerns me is I'm sure they probably have very little if any experience with a 496 Mag HO. I hope they are good because they are by far the most convenient shop for me to take my boat to.

I would call park marine and ask for kevin. the tech there is a merc master tech and has quite a bit of experience with performance boats. Tell him Eric and John sent you

Thanks for the tip. I felt much better about them after talking with Kevin and took my boat there today! Now my fingers are crossed hoping it's something easy!
