PertronixD200810 Flame-Thrower Black Cap Male Plug and Play Black Cap Male Marine Billet Electronic Distributor with Ignitor II Technology with Black Cap Male for Chevrolet Small Block/Big Block

I used it for a 305 mercuiser '93.It wasn't a success. Returned it a bought the msd marine distributor. Huge difference in revs and in pick up. I installed Pertronix the exact same as msd and couldn't get it to fire. Msd woke it up.

Added this to my boat motor and what a difference. Great !!!

Seems to be just what I needed. Everything is all in 1 place. Perfect

Not sure what to think of this put it on my boat and it wont fire think it might have a bad ignitor so I had to order a new ignitor to see if is just that or this product. The thing that sucks Is I wanted to replace the hole thing but they say it wont show up for 3--4 weeks who want to wait that long for a part. Called Pertronix to run different test on it and they told me to buy a new ignitor so now im stuck spending another $ 100 to see if that is the problem. Pertronix said they wont replace it unless I sent them the old one so they could test it after I just ran all the test they wanted to me do. NOt sure what I think.

Honest accurate description, shipped immediately, packaged extremeley well. Excellent company to deal with. Writing this review for Amazon is far more difficult to deal with and a lesson in overkill.
