Hello, all. I have a 2001 Sea Ray 240. She was blocked up and of course, winterized until launched 2 Sundays ago. We have only had her out twice for short trips. The speedometer does not register any speed at all. The backlite does work. I checked the wiring diagram in the owners manual which shows the power to the other guages in the dash powered together, and with the backlite working, I'm thinking power is not the problem. I checked all the fuses also, there is not one dedicated to the speedo. It worked fine previously. I do not think it is related, but I installed a fixed mount VHF radio and 8' antenna a week or 2 before launch, but used a previously unused accessory slot in the fuse panel, just under the steering wheel. This does not use the pickup that hangs off the back of the transom. TIA, Eric
