MY 1989 (year i was told)MERCURY XR2 LEAKS DOWN SLOWLY.WHERE WOULD BE MOST LIKELY PLACE TO START LOOKING FOR PROBLEM. ALSO I SEE A LOT OF MESSAGES ON ENGINES LOSING PISTONS DUE TO CARB FAILURE. ARE THERE ANY WARNING SIGNS? I THREW A ROD THRU THE SIDE OF MY JOHNSON 150 A COUPLE YEARS AGO AND WOULD LIKE TO AVOID ANOTHER PROBLEM LIKE THIS.
