Electronic Ignition part number and Non-Resistance spark plugs

[hawkhunter8]

Does anyone have the part number for just the electronic ignition for a 1973 mercruiser 120? the 1146a will not work. 1142? Perused the Petronix site but it seems a bit vague. Also any part numbers for a non-resistance spark plug

Welcome

Does anyone have the part number for just the electronic ignition for a 1973 mercruiser 120?

Folks have had a lot of problems from Pertronix so I would not recommend them for marine applications. I would suggest Delco EST Kit

Delco EST

You don't need non-resistor plugs, you won't get any benefit from them other then the coil drawing more current and burn out sooner

 

[hawkhunter8]

That doesn't really answer my questions, but thank you for your opinion.

My bad, forgot to end with contact Petronix and ask them, they are on the web
Don't know of non-resistor plugs

1146 is the number for a Delco distributor in a 120. 1142 fits some tractors albeit also Delco. It’s the base plate that is a little different but module is the same.

If you want just the trigger because it’s not working ( common ) then call Pertronix for service.. there is a reason pertronix isn’t recommended here

Actually an 1146 does not work on a (my) 1973 Mercruiser 120, the ring is too small to properly fit over the distributor shaft. It appears 72-73 may be unique in some way.

the Delco distributors used never changed. Unless you don’t have a Delco. The ring goes down tight. You really have to press on it. Or it’s out of the box defective

Thanks, I reefed on it pretty good. I was wondering if the distributor was swapped out or, as you mentioned a defective ring. Thanks for your help.....maybe I'll stick with points lol.

Personally I would stick with points vs ever considering Pertronix again

I've had good luck with Pertronix on 'land based' vehicles in the past. Wonder if quality has dropped off that poorly since I last bought one.

They are not well regarded in the marine side of things. Known for burning out and burning coils out

Good to know, thanks!

Then you have had better luck than I have

Mine failed in everything. Didn't matter if it was a car or boat

I used one in a car and it was a hot pile of s***. I'll dumpster dive for points before they ever get my money again...

 

[hawkhunter8]

Makes me wonder how they stay in business.

I've ran Pertonix ignitor kits in my old ford F100 and two older mercruiser V8s (228 and a 260), and personally I've never had issues. All motors started/ran instantly better after installing the kit & coil.

Like anything, I'm sure they have had their issues but personally I wouldn't hesitate throw them at anything with points. Had to use their support line for my last boat as I decided to go with the ignitor 2 system, and they were super helpful as I had to bypass the factory wiring.

Sorry, I dont have a part number either but I believe they have an online catalog that includes the merc stuff and it was always easy to figure out what's needed for each application.

Same in the classic car /GTO forum I am on as well. if the op wants electronic ignition for a 120 get a genuine Delco EST (aka not a knock off) and you have an OEM quality system

Thanks for the input. I contacted pertronix And they need the distributor number to give me a part number. Unfortunately the boat is at my other place so it'll have to wait. I know pertronix sells tons of these and have for decades.
