    I had an old 1971,125 hp Johnson, that used to do the same thing. Back then, there WAS no optional regulator.So, I used to watch the voltage and run the power tilt in the down direction, occasionally to knock the voltage back down. You just need to add some more fishing equipment and lighting, to get it under control. You probably only need to find about five more amps. (You have the opposite problem from the Apollo 13 crew!)

    Long live American manufacturing!
