I have an olds 350 in my boat with a mallory single point distributer in it and at avi with all you scjb guys in october I had some ignition issues down at the pirate bar on saturday. I thought we found the problem because she fired right up and ran great the rest of the day. well the next 2 trips out she did the same shit and would just fire up again out of no where. So heres my question I want to drop a pertronix and new coil in it as well as rewire the whole motor. Which pertronix and coil do i need to get? or is there a better route to go then the pertronix? Im not really worried about getting more power out of her just reliability.
Thanks in advance guys.

Here's the one I used in my Model A

and your coil

I don't remember you having trouble at the AVI. I'm kinda old, but probably wasn't part of that! :D I do remember the Laker Boat coming it at Big River limping like a blown engine and Nick (CJ222) and Ralph practically rebuilding his carb right there on the beach and he was golden in about an hour! So I'm with you on the SCJB gang! Can't find better peeps anywhere! :thumbup:
The Pertronix will probably help many things, but an intermittent ignition failure would indicate POSSIBLE other issues that I don't think it's going to fix bro! Given what I know of the situation.
Yes wiring, for 1. But is water getting to the dizzy through a small, spray like leak from the pump or even outboard spraying in (Ask Crewcheif about that one, he warned me ahead of time for this on Chebbies with Jacuzzi's, why does he have a splash guard?).
I had an issue with a boat I still own, but is, well, in Davy Jones' Locker at the moment and probably permanently, that did something like this as well and it took the Vegas crew (OC2, Nordie and HDRider) to figure out it was the ignition switch, and possibly a couple bad wires at the engine. A $16 fix that I know Terry was stumped on big time for a bit!
Same thing happened with Moo. After I built the engine (Built for another boat, really), and installed it, the wiring, plumbing, et al, went to fire it up for the first time, put the key in and nothing, several times! Pulled the key out, the whole guts came out with it. Did fire it with a screwdriver but wouldn't stay running, had to hit a marine store the next day for a new switch. Now I carry one under the seat of each boat.
Be careful just changing things out without figuring out the why's, IMHO. (I'm knee deep into a similar debacle figuring out where a gallon and a half of water found its way into Moo's engine. Not an easy thing sometimes, but best to get it right the first time by asking why?) You're making the right decision to go electronic, I'm just not convinced it's the source of evil. >:D

I did the pirate bar run on saturday with a few boats when all you guys went up river. I 100% agree with you Ray But whenever she dies and quits running I have power going into the coil and power out just no spark.... we pull the cap and its dry im thinkin I could be as easy as just a bad coil wire or possibly the little porcelin resister but I hate points so Im just gunna change it all for peice of mind.. Im a fan of simplicity and have always had luck with pertronix in my vw's (except when I hook um up backwards :banghead:) I ordered the unit and coil last night so we will see.

I had one that the rotor had a micro small hole and intermitently shorted to dist shaft causing craping out and no start ???

Did you check the voltage off the backside of the ballast resistor? That's where my mallory junk always puked.

Just put a HEI in it and be done!
Procomp electronics makes one for it!
