Hi,
Recently bought a boat (Four Winns H170-Volvo Penta 3.0) and have been doing maintenance on it. When I start the boat up, the tach shows that the engine is idling high 1200RPM's. It seems to me that the engine is not running that high. I then noticed that when I first turn the key (first position) the tach goes up to 300rpm's before the engin is started. Is this normal? Could it explain why I'm getting high RPM's when I'm actually not.
