Re: Mercruiser 3.0l cuts off at high revs.
With the vibration and bouncing around especially on a 3.0 I have found that a good by-weekly check of all electrical connections is a good PM to avoid such issues. Also before you start start it in the dark w/muffs on and look around all the connections and look for a blue colored spark wiggle wires and connections this may help isolate a bad connection, you should also do a continuity test on all plug wires.
