I just bought a boat with 200 efi on it. It has oil injection still installed. I was running it for the first time sunday and we ran across the lake at wot. Ran for maybe 10 minute and it just shut down like the key was turned off. Tried and tried to restart. Finally got to look at it when i got home and the wire going to heat sensor jacket was melted. There was not any alarms going off or anything. Any ideas?
