I have a 2000 MC X-5 and last Saturday, after we had just got through emptying the sacs, we were running back to the ramp a little faster than we usually do (about 33-34 mph) and I went to slow the boat down pretty quickly as we entered a "No Wake" zone and the speedos along with the tac stayed stuck on the 33 mph and 3500 RPM. No matter what speed we cruised around at after that, they stayed stuck...we tried running at various speeds for about 5 minutes and then gave up and put it back on the trailer.
Has anyone experienced this before? The speedo pickups appear to be on the rear under the swim deck (this is my first boat, so I'm not 100% sure). Is there a chance that the pickups are clogged and/or damaged or do you think it is an electrical issue?
Any help and or advice would be very much appreciated. Thanks.
