    Default Misfire cylinder 3 & 5

    Motorcraft SP526 and CYFS12FP are same plug.

    Again, $4.05 each on Amazon

    Here are all the rock auto equivalent plugs.

    Factory are double platinums.




    Factory coils are Densoís and $58 each on Rockauto

    They label theirs 1-4 on one side 5-8 on the other.
    So if you’re looking at the engine from the swim deck (cus that’s closest to the front of the motor) 1-4 is on the right side.

    Ford:
    8 4
    7 3
    6 2
    5 1

    GM and everyone else in the known universe:
    8 7
    6 5
    4 3
    2 1
    Are you sure about this? I am relatively new to boats, but was an automaobile mechanic for several years. Ford cars always numbered 1 - 4 on the PASSENGER side of the car. If you were standing on the swim platform, looking at the front of the engine, it would be
    4 8
    3 7
    2 6
    1 5

    Yep you’re right... I was thinking of the GM motor to show the difference and put cylinders 1 on the same side. Good catch, lol
