I have a hard time envisioning why anyone would have serious speed holding concerns below surfing speeds (9mph?) unless youre in a no-wake zone or pulling a small child like ETS mentioned. Either case would seemingly benefit more from keeping a close eye on your wake/child to make sure speed is appropriate, rather than keeping an eye on your speedo.
Skiing speeds are most important for accuracy, but knowing the difference between 47mph and 49mph are more important to me than <6mph. I have some boats that will peg the speedos and then some... so maybe the opinion of this mouth breather doesnt count? ![]() |

Dean.....if you set the speedometer to be correct at 50 mph, at what point would it be accurate at the low speeds?

Most boat speedos are not very accurate at low speeds, so not loss there, but it would really, really bug me if the speedo range did not include the top speed of the boat...

As long as it's accurate starting at 8-9 it should be fine.

If you choose the high end the needle will settle at 5 mph. So you have a couple mph and maybe a post that the needle will not settle at. This is a visual difference in my opinion. Will you be bothered that your needle is not settling at the bottom of the scale when your boat is stopped? If you choose the low end of course the opposite is true. Needle settles at the bottom of the scale but can not quite reach 50 mph. Each speedometer has to be calibrated to its dial scale. You will have the choice of top or bottom of the scale accuracy. I think it is an aesthetic issue when your boat is stopped an accuracy issue at the top of the 50 mph scale. Other higher speed speedometers will get a different calibration. I haven't tried yet but an 80 mph model 2025 might have to start at 5 or 10 to reach the full 80 mph (I am guessing here) the scale is very close to the 3 to 50 mph scale. Assume the calibration has to start at 10 to reach the full 80 mph. You would have the same issue. Do I start at 10 and my needle doesn't go to the bottom of the scale or start at 5 and come up slightly short at the top end? |

The Bad and the Good
The Bad and the Good
First the Bad: I withdrew my participation in the development of the GPS retrofit with the company I was working with. The business terms are simply unacceptable. Now the Good: I am not stopping work on the development of a retrofit. I have already begun working with two sources to engineer a retrofit board and a frame to hold the board in the proper position. My goal is to have the board fit onto the frame so you remove the mechanical mechanism and replace it with the new frame, attach the board, attach the dial, attach the adjustment knob (if you have one), and close up your speedometer. I will use your input in the design. Dean |
