speedometer not working in my 04 moomba mobius lsv. The paddle wheel looks and spins fine. I noticed the plug from the assembly has sat in the bottom of the boat in water all winter. The paddle wheel assembly is an airmar shorty ST300. any suggestions to what might be wrong or where to buy a new paddle wheel assembly if needed?
I am not sure of the det up you have. My old boat had the same problem. I had a hose from the pick up to the speedo. I pulled the hose from the speedo and the pickup and blew air through it. This fixed the problem. Hope this helps.
Sorry for bringing up an old thread... My boat is having the exact same problem where the speedometers don't read, they're always at 0. All the wiring is fine, no bad fuses. It looks like the plug (although it has a seal) got some water in it. Does anyone know where to buy the replacement plug and paddle wheel assembly? Thanks for your help!
This is the same problem that I am having, wheel seems to spin freely but both the perfect pass and the regular speedo read "0". Where is the fuse I can check? Do I need to take the floor out to see the connection? On the plus side i got my new boat lift put in at my new to me lsv is sitting on it!
I hope you're putting up pics of the boat and lift.
new lift pics
Ahhh. Thats better. I had a pic craving.
does anybody have any advice on this problem, as it sucks with out a speedo and perfect pass not working?
I'm having the same Speedo Issue. Except mine is after an accident and 12k worth in fiberglass work... :)
I think maybe they screwed something up. UGH...
When the Rain stop here in Cali, I'm gonna start digging and prodding. Does anyone know where the fuses are for Speedo's, and possibly have a wiring Diagram?
I had this same problem a couple years back on my 05 Outback. The plug-in assembly was sitting in the bottom of my bilge and also go water in the connection. I simply disconnected it and dried it out real good. When I reassembled it I zip tied it to the wiring harness running along the inside edge of the bilge area which is above the floor of the boat. Have not had the problem since.
I had the same problem last year but this year everything is working fine.I bought some connector cleaner at radio shack and put some in the connector.I plug and unplug the connector 9 to 10 times and now everything seems to be working fine.
But when the problem comes back, I would spend a couple of more dollars more and get the Star Gazer Upgrade . It is a Perfect Pass upgrade that uses GPS instead of water and the wheel paddle to indicate the speed of your boat. No more problem with speed sensor under the boat.
Apparently it is a simple job that takes 5 minutes max, unplug the old Perfect Pass module and replug the new module with the GPS Antenna. It runs for about $480.
Here is the link...Hope this helps

Ok, I figured it out. The plug took on water so I dried it out but it still didn't work. I noticed that one of the wires (the red one on the paddle wheel side of the plug) was loose and it pretty much fell out of the hole. The water that had entered through the plug corroded the wire to the point where it broke free. I cut the plug out and attached all of the wires with those little crimp connectors then ran heat shrink over them. I zip-tied the wire up so it won't get wet. Now it works like a charm. I would assume that this is the cause of the failure for others as well.
4fish4 - I bet you have a wire that is loose that's about to go. It could be hitting and working then separating and not working causing the erratic speedo...
Great tip! I had an erratic speedo and perfect pass today in my 07 Outback V. Most of the time they read 0 but sometimes they'd be ok and other time read too high. Found this thread and found the connector coming off the paddle wheel filled with a green slime and the red wire pin corroded down to bare copper. For the time being I cleaned everything up with contact cleaner and lubed with WD-40. Test drove and all is good again. At least I know where the problem is and if it continues to be an issue, I'll look for some replacement pins or connector.
Everytime I take a wave over the bow on my 08 Outback my speedo quits working. Even after the bilge pumps out all the water. Once I get out of the water and pull the bilge plug, drain it completely and let it dry out a bit, the speedo will work the next time I go out. I'm getting better at not taking waves over the bow (new driver) but any other tips would be appreciated.
I'm having the same issue. Does anyone have a picture of the wires and plug in question so I know what to look for
Which boat do you have?
