What year boat/motor/ignition system are you asking about? Also, is it stock or modified?

Hi, thank you. OEM. I think I learned it does not have one. Likes full 12 volts and a low resistance coil. PCM Prestolite breakerless induction distributor is on a 99 SNOB, 5.8
Found a great test manual/procedure by Indmar for same distributor. I am following those steps for now. Thanks again.

damnit. I measured the 87 PCM 351 in my garage and the ballast resistor came in at 1.8 ohm (loose terminal) and the coil was 1.7 kind of as expected. A stock 88 coil I measured over the summer was 1.6. I was feeling like KenO for a moment.

I was far too lazy to uncover my 88 and check it, and was supposed to ski tonight behind a few more late 80s CCs but the rain isn't going to allow it.

I can't think of anyone here with a late 90s carb boat at the moment.

You're much better looking though

If you really want to feel like me, you have to cut a coil apart to see what's inside

I have pictures of the inside of one, I think I put them here on CCF. I'll have to look for them.

For Tall Tex you should put a link to your find for the rest of the world to see and learn from

It might look like the one below

Call Vince at Discount Inboard Marine. I'm sure he knows. He told me to look for 1.8 on my 93, if I recall correctly. They are the best customer service I've ever had anywhere.
