I see a few other topics dealing with similar problems as mine but don't see their problems<br />were ever resolved. I recently reported my 1968 55hp Evinrude stopped running, receiving<br />little help I determined it was the Amplifier Assemble ($310) bucks. After installing a<br />after market Motorola/Delta Amplifier that I was told was more better then the factory<br />equipment. Tested 9.9 volts in, 12.3 at beginning of crank but leveled out at 9.9 during crank.<br />Output to coil around 240 volts. Battery excellent, Points new and adjusted, Start tested,<br />Ground checked, she started right up smooth as ever.<br /><br />Launched boat, Started motor and stopped a dozen time within two hour, beach for lunch,<br />pushed out into deep water, hit key only to hear engine pop and starter kicked out. Happened<br />several time, finally engaged but failed to start. Start tested to be good, tested input to <br />amplifier, 9.9 volts output Zero, dead again.<br /><br />What on earth could have already ruined a new assembly in two hours time?
