Volvo Penta AQ125A/270 combo. When I came in yesterday, I forgot to raise my outdrive and thank goodnes remembered before putting the boat on my trailer. To raise it, I had to turn my key on again but unfortunately, I forgot to turn the key off. The next day, I was out by the boat and heard ticking. Yep, the hour meter was turning. Outside of the extra hours that show on the meter, could I have screwed up anything else?
