    MSX 140, 150 top speed

    What kind of top speed are people getting out of the 140s, 150s anyway? Donald

    The 03 MSX140 is roughly 57-58 MPH and is actually rated at more like 118HP.
    The 04 MSX140 with the hull changes, ride plate and roughly 35 pound diet of the front end is roughly 59-61. There may have even been some engine refinements as well??
    The MSX150 has always been around 60MPH.

    I know these skis are a little slower top speed then a STX15F, but what about accelleration? And handling? Donald

    The MFD's are not close. If your boat is stock then you should be right around 58ish. The faster the boat goes the larger the margin of error in the speedo. This is why I didn't upgrade from my X45. It was quicker than the MSX (although the MSX is prettier).
