My season has officially come to an end. Both motors have crapped out and will not be rebuilt until winter.
502 efis all stock. Refreshed after last season and I got around 40-50 hours on the motors since refresh . Spent the day running fairly casual around 40-60 mph an occasional punch up to 70mph never hitting full wide open. Suddenly the starboard motor felt a little sluggish and when I slowed down to an idle I opened the hatch to find oil everywhere. Had to shut both motors down and was towed in.
Temperature was normal on both motors, had good oil pressure and didn't run the boat hard at all. One motor melted down the 4-6-8 pistons and the other motor had a hole the size of a dime in the top of the #8 piston. Any theories out there? I find it awfully odd that both motors crapped out at the same time, and in addition I ran the boat all summer without any problems.
