Axis Wakeboard Boat Forum

Currently my speedo will not go over 26 MPH......cruise fine at 9-11 and up to 19-21 then I turn the cruise off come to a stop and take off to come back to dock and speedo analog and actual only say 26 or so. I know I am running faster than that at WOT because the RPMS unloaded tanks empty is like 5100-5200

So I have the manual but it doesnt give a good description on how to calibrate it.

Also air temp and lake temp is reading about 10 degrees to high.....can you calibrate these too?

Everything was perfect at start of season......showing 45 to 47 MPH on both gages

Is there a way to re calibrate everything? I keep my boat in the water at the marina. Just been there out of storage for a month or so now. I even lifted the boat on someone else's lift to check the paddle wheel and it rolls fine.

Any help would be greatly appreciated......I would like to know where all theses sensors are located and how they work.

Thanks in advance

No suggestions? Any Techs on here?

For the speedo you need to have some type of GPS (I used a free app on my phone which was pretty accurate).

Start the boat and wait for all of the gauges to be on. Press and hold both buttons under the center gauge for 1-2 seconds and it will beep and sent you into setup mode. You can then scroll through and setup the speedo...i think it says "calibrate"

if i remember correctly you increase or decrease by a % value.

Maybe your paddle wheel has gone bad. The lake temperature sensor is also in the paddle wheel
