I was out on the lake in very choppy conditions (winds 20mph ) with a full passenger load.
Riding well most of the day then notice my speedometer stopped working. Drove a bit further stopped the engine and restarted. It was working again. Then after 5 min of travel, the engine would not rev to get to speed just seemed to bog down. I stopped checked the prop (ok). Revved the engineer with prop disconnect and it revved fine. Restartsed my travels and all seemed fine (given the choppy conditions)
Any thoughts on what causes these issues and if they are related?
