Setting Speedos?

Recommended Posts

kknudsen12

We just bought a used RLX, our first inboard. It has the traditional speedos, and unfortunately the knobs that adjust the speedos got turned… thus, they aren’t showing the correct speed. How do we get them back to showing the right speed? There’s maybe a really easy way to correct them, but I have no idea how to do it. Thanks!

Get (or borrow) a GPS unit and calibrate them that way.

If you have a stopwatch and ski course available to you, you can set them that way. Here is a chart

34.2 7.13 7.05 7.22 9.82 9.70 9.94

36.0 6.77 6.69 6.84 9.31 9.21 9.42

Hope that helps. You may want to paste the chart into excel so you can line up the columns better.

I have been needing to do the same thing and this is super helpful. it would be more helpful if I know what the Segments are...

when i first saw the title, i was going to say either to the left side or right, but...

if you don't have a GPS or a course, i read something somewhere where you could adjust the speedos without even knowing the distance between 2 points. I will see if I can find it.

and by the way, remember that the speedos are non linear, so when you adjust them for one speed, they will NOT be right for another. So adjust to the speed that you use the most (or, adjust one for wakeboard speed, and one for ski speed).

Just add the two up and call run the whole course from gate to gate.
