    Was this really a test, it sounded more like a commercial! Captain Robert must be on Mercs payroll.

    What is the cost of this in an HO version? Thinking of going this route if Axius and digital throttles are reasonably economical. Anyone have any guesstimates?
    c,hughes 4/14/2008 10:45:27 AM
    I really like this engine. I have not been the best boater when it comes to taking care of my engine, but this one just keeps on giving. Worth asking for when you get a new boat!
