Just got a call from "Rons Marine", bad news, #3 piston got stuck and scored the cylinder wall leaving very little compression. They are talking about a new power head approx 10 day turnaround. (used xd-100 exclusively) I'm not even sure if I got through the break in time. My experience with motors has been "once a lemon always a lemon" looks like bad things to come in the future, at least it's under warranty for 5 years, just hate the inconvenience of back and forth to marine dealer and tournament time loss!!
