    The guys with shops that come on here will need serial number of this motor.
    Not long after getting my 250 EFI new a coil went bad and I lost lots of rpm's. Took it to Certified Marine in Lakeland and they plugged the computer in. It didn't show anything, I had to pay them to lake test it. Then the idiots didn't even pull the plug, even though their shop has signs about making sure you do. Had a record one day rainfall total. I go pick the boat up days later 1/2 full of water. I thought it would be ok with them saying it was 100% composite. Wrong!
    Anyway. Good luck.
