Ignitor Electronic Ignition Conversion Kits have proven themselves in applications ranging from race cars to tractors. It is the number one Electronic Ignition Conversion Kit to replace original mechanical points. A Pertronix Points Conversion kit allows you to run a stock distributor while improving the reliability and performance of your ignition system. The Pertronix Ignitor kits simply bolt to the distributor in place of the points assembly and provides a much more accurate trigger signal. This improves the timing accuracy and prevents ‘points bounce’ at higher rpm. The electronic technology also improves the dwell control to improve the spark output of the coil resulting in a hotter spark at the spark plug. With this dependable, self-contained, maintenance free electronic ignition system you'll never replace your points again.

Tried every diagnostic I could and followed the instructions, would not fire the coil. Trying another one then going back to points if it doesn't work.

Easy installation on my mercruiser 3.0L, and a great upgrade to the points that I had. It does require the addition of one wire that goes to ignition power for the system, but other than that it's a drop in replacement. Requires no adjustments.

Customer service is great! I ordered one and it didn't work and I contacted them on here and they sent me a replacement one before I even took mine off to send it back. I had it in one day.. the product it self is great. Starts right up, runs smoother, and idle is more consistent. It works great with my accel super coil too. Things to note; remove resistance wire and replace with regular wire. Shave the cap for the wires. The magnet does not sit down far enough on the distributor shaft. It's about an 1/8 to high. U will need to shave the rotor down as well... I am very pleased with the product. If have any mechanical ability, this will be a breeze to install.

Works great, but don't be surprised if you have a low idle problem. It is not the Pertronix, but rather the new rotor you probably installed with it. Sierra Mfg is sending the wrong rotors and they have too big of gap, thus causing slop. This slop allows the rotor to move a few degrees back and forth and causes the low idle problem. Once I installed my old rotor the problem was fixed. Search YouTube for Pertronix fix and you will see the video for the fix.You do have to file a small notch in your rotor cap for the Pertronix wires and probably file down your rotor a little for a perfect fit. Both are easy to do. The round black magnet used in the Pertronix kit causes your rotor to sit a little higher. This caused mine to slightly rub the top of the distributor cap. I filed down the bottom of the rotor and it fixed the problem.Pertronix works great, I have smoother idle, better fuel economy, and this may sound weird, but the engine is quieter at running speed.

This kit requires some modification and trouble shooting to get it right. Installed it on my 1988 ChrisCraft cavalier with a Merc 3.0. You have to notch the distributor cap to fit the new wires and I was still having a severe mis-fire on cylinder 3. Turns out you have to take a socket and lightly tap the sensor ring onto the distributor shaft, it doesn't fit on all the way by hand. After that it ran great for about a day, then just stopped working, caused a backfire that blew a head gasket.

I installed this prior to winterizing the boat, but it fired right up and idled the best it's ever done in the 8 or 9 years I've owned the boat. It's a 1988 Mercruiser 3.7L engine.I haven't had it out on the water yet, but I suspect I will no longer have idling issues where it dies or I have to gun it to keep it running!
