    03 Sea Doo top speed?

    I have a 03 Sea Doo GTX 4 tec 185HP with a new wear ring and top speed is 50. Everything else is stock. Should I be over that? Whats the best upgrade for the money?

    I think that ski should go at lease 57 to 60. I may be wrong. A stock gtx 155 HP will go 53 to 55

    50mph on the Dash or on a handheld GPS unit?

    7300 sounds about right...... maybe it's just the speedo that is out?
