It might just be my boat but the speedometer had never worked properly. It started messing up 6 months after I bought it new by sticking on a certain mph or not at all. I had taken it back to the dealer and they instructed me on how to unclog the inlet hole. I have to unstop the darn thing maybe 3 or 4 times a year. I went fishing Sat and it never moved. Is there anyway I can keep this from happening so frequently.
