Four Winns got back with me today... they have no parts or service for a 2000 model year. They did give me the name of a place to try ( AAmarine@classicboating.com ), I haven't emailed them yet.
Does anybody know of a company that rebuilds electronic dash consoles? Speedometer and engine temp not working at all on my new to me 2000 Four Winns 200 Horizon.
