I ordered this ignition replacement for a 153 Chevy 4 cylinder (120 Mercruiser) stern drive. Prior to installing it I was experiencing backfiring through the carb, difficulty starting, and weak spark in the cylinders. I have a replacement Mallory distributor with the breaker points system. I opted for the Pertronix replacement because I didn’t want to buy special tools, and have to deal with adjusting points. They were fairly worn anyhow so I went with the modern technology.This unit has made my boat run like brand new. Starts instantly, no backfiring, and great throttle response. No maintenance is a great bonus. A word to DIY’ers – I did have to adjust the timing after installation, the unit advanced my timing 8 degrees. Also it’s kind of a pain to get the plate in place properly since the screws holding it to the distributor body also hold the cap clamps, and the nuts are underneath. Still an easy install, just be patient.

Pertronix Ignitor installation was easy. I installed it in a 2.3 liter OMC Cobra I/O boat motor. I do suggest calling Pertronix and speaking to one of the technicians there before ordering. Tell them what you have and let them do the conversion to the correct Pertronix P/N. Very helpful and knowledgeable people.

Used it on my boat OMC Cobra 2.3. Works great n easy to install. I was having a problem with the boat stalling out n not starting back up after about a 15 minute of run time. With this install it doesn’t stall out any more.

Installed it together with the Flamethrower Coil 3ohms on my 2.3 OMC Cobra sterndrive and the difference is remarkable!Installation was easy and selfexplaining. Whe the wiring diagram it is easy to install a new +12V on ignition power line. I chose the terminal on the alternator and put a wire from there to the IgnitorI module.Engine start better, has a very smooth idle for a four-cylinder and reaches now its max rpms with the recomendet prop.Is really worth it!

Remove points and condenser, then literally drops right in. Really simple. Run wires to + and - terminals of coil and, viola! Done! I also added a 1.6 Ohm ballast resistor before the coil, to match what Pertronix wanted for 4-cyl engines (greater than 3 Ohms total). She runs!

It worked like a charm. Need to make a "interrupt" fix if you are installing it on an OMC inboard engine.
