hour meter

[gtreanto]

I had a new to me used F250 rigged on a boat I am restoring. Yamaha tech tool connected to the engine shows approx 340 hours. The tac is from the old engine and still displays the old engine hours. Is there a way to sync the tac hours to the engine hours?

Never mind. The hours on the tach represent key on hours and not engine. No way to change. I'm all set
