I am replacing the coil on my 1990 Nautique which has a PCM/Ford 351 engine. Polarity is indicated on the new coil, but not the old one. Which wires go on the Positive(+) side of the coil, and which wires go on the Negative(-) side? Thanks in advance.

Coil
I just replaced my coil this weekend and can confirm... purple positive and gray negative. This is my boats third coil. It has 860 hours. I always thought coils were bullet proof. But second my boat feels like it is missing under load and at high rpms. A $20 coil has always fixed the problem.sigpic
