mph

i am new to jetskiing, and after a season with my machine, im eager to increase my top speed. my top speed now is about 63mph, and i want to see how much higher i can go. thanks.

My (left) digital gage is only partly working. I can press mode and go to all of the different modes MPH, RPM, etc....it shows 0 MPH and it will not change from 0. The rmp shows and goes up and down, the compass shows and is correct when cirection is changed. The gas gage/bars do not show. Why...
