This little boat is just a blast to drive and does really well with the little 80hp Merc . I bet would be sweet with a 150 Inline six . That just might happen when I get the Vmate finished ...... This is the first time I had the motor running and it was surging . After looking everything Over I found a bad fuel line . I replaced it and it ran alot better . But at the end of the season the rest of the lines have just fell apart so ill be doing those this spring as well .
