Hey everyone - I have a 19 foot tourney that is powered by a 200hp Yammy and just the other day i was out for a cruise and the spedometer started going nutty. I would be in neutral and the spedo would read like 6 or 8 mph. Then when i put it in gear it seams to lug a little bit when cruising at speeds under 10mph. I'm not sure what's going on or if i should even worry about it, but i'd like to have a speedo that works and if something is going on with the motor, i need to know that too. Anyone have any suggestions???? Thanks!
