I just totally rebuilt my 140 merc,fisrt day out no problems wot plenty of times and trolling or 5hrs, until I went wide open to go back to shore,engine failed,just bought a hand held the night before,no kicker on the boat, but the canandian coast gaurd(tow boat) came to the rescue. Actually in better time than a tow truck would and at no charge, bonus.Have a kicker now no engine problems, My radio is always on, for stranded boaters etc.I sure learned my lesson alright.
