The previous owner of my boat converted the PerfectPass to GPS with the kit available from NauticLaugic (ugh, the spelling) and it's been working great. Until a friend was using the boat, and it spontaneously started acting up, at least according to their retelling of the events. In any case, I figured they must have accidentally pressed some combination of buttons and toggled some simple setting causing the issue.
The symptom was that it was reading speeds waaaay slow like, 5mph was 1mph on the PP gauge, and 30mph was about 10. It went up and down, but was off by a lot, making it utterly useless for speed control.
I read through the PerfectPass documentation and the NauticLaugic documentation, searched the web for information on KDW and NN settings, initial setup, menu structure... then spent probably 30 minutes messing with it on and off while waiting for my suction oil pump to finish up yesterday. There's lots of chatter on the web about adjusting these settings and why, but none of it seemed to make any difference at all, which honestly didn't surprise me. There's just no way they accidentally changed the NN setting, right? It would be like someone accidentally resetting the oil service indicator in a modern car - it's such a specific sequence of things that there's no way you'd stumble into it.
In the end, a simple reset solved the problem. The reset was done by holding the ON/OFF and MENU buttons while powering up the system, then confirming by pressing the UP key when prompted. There was a second prompt, I don't remember what it asked but I declined that one.
Despite the reset, I didn't lose my hour meter in the PP gauge, thankfully, because it appears to have the actual boat hours (606) unlike the tach which reads 3,902 + as of yesterday. So now I learned a little more about the PerfectPass, although I have no idea why it did that. And I confirmed that my boat indeed likely had around 550 hours when I got it, as the owner said (we've put 58 hours on it so far this year). And my friend doesn't feel bad because he didn't actually break anything.
I thought I'd share for anyone who might have this issue in the future, in the event that Google can lead them to a solution faster than it did for me.
Happy Labor Day weekend!
