I was out on the boat on Friday and saw that my tach was reading too high. It sounded normal, and I was going the same top speed as usual. Looked like it was about 700rpm too high. I stopped the boat and turned off the motor. Started again and it still read the same. Went to the beach in the back of Saguaro and ate lunch. Idled back out and then everything looked normal. I don't like when I see a problem and then it goes away for no reason. Is there something I should look at? The engine is a 454 TPI Mercruiser w/Bravo 3.
