Guys, after more reading,I know its the speedo or the pick-up in the tail shaft.So I figured to look at both these this week. I took big blue out to 495 interstate to clean out the motor. About 10 minutes at 80 or so does the trick. Low and behold, does't the speedo start to work. Now it seems fine, for how long,I can only guess. I guess I should check it anyway, but I'll wait. steve
