Nautiqueparts still lists those replacement springs.
It actually is normal for them to be two different sizes. Someone else may know the reasoning on that. http://www.nautiqueparts.com/distributorsprings.aspx |

Those springs say 1987 or newer. The distributor pictured looks to be a clip-on Prestolite which is 86 or older. I don't know if they'll work but they're not the springs made for that distributor. I don't know where you get the springs for a clip on but when I was looking I couldn't find them. I ended up just getting a new distributor. Springs weren't my only issue though. |

You mention adding a new fuel filter. Is this just before or after this problem started?
By mistake I installed a fuel injection filter in my carbureted 350 GM powered Malibu Skier a few years back. It choked the fuel supply because it was a 10 micron filter and the mechanical fuel pump could not pull the fuel past it fast enough. The carbureted filters are 20-30 micron and flow better for a mechanical fuel pump. Fuel Injectors need a fine filter but carburetors need more flow so a larger filter screen is used. |

It was after, that sort of possibility actually crossed my mind but the symptom showed up prior to the new filter. Actually it prompted me to change it |

Maybe you have a worn timing chain. You can test for this by manually turning crank back & forth while watching dizzy rotor. Any lost motion means worn chain.

It's almost odd that you mention the carb bringing it full circle, I rebuilt the carb and struggled for a while with some vacuum leaks due to poorly fitting gaskets. So the very same day that I got the idle squared away, this symptom showed up and burst my bubble. While it was idling poorly, it would run seemingly fine at higher rpms, now it's reversed. |

I did this earlier today, do you mean absolutely any lost movement? I ask because I'm fairly certain there was some. |

If there was some, that means worn chain. Can't say that is causing your problem but it might be an upgrade for off-season.

Anyone have a wiring diagram for what the ignition system SHOULD look like, I'd like to double check the wiring for any shorts or obvious stuff before spending $$$ on something like a distributor.
Also, any part # to take my boat back to points ignition? My boat is an 83 and I know a lot can change or be messed with over the years, I think it's worth a try. Also I've read on many threads here that the EI conversion kits are junk. If really like to get this squared away before the end of the season. |

When it comes to EI conversion distributor issues I'm not a fan of Tim's diagram...

There is always going to be a little play in the chain The link attached here explains things pretty well and since you're checking your compression tomorrow that can tell you something about the chain and gear condition too. http://www.misterfixit.com/chanslop.htm If you check by the link, your harmonic balancer is 6.5 inches in diameter when it comes time to do the math |

Could be just cuz he's Hollywood or probably because different electronic conversions/distributors hook up in different ways and some retain the ballast resistor and some don't so that part of the diagram might change depending on your setup |

The Petronix EI Module has failed.
Go to Amazon and order a new one. Once installed. Make sure you have the jumper in place as shown in the diagram above to ensure you're getting 12v to the positive side of the coil and test with a meter.. Run a dedicated ground wire from the plate in the distributor to the negative post of your battery or a good ground on the block. (back right side of engine has a grounding point) Make sure your rotor is seated properly and that the distributor cap is securely fastened down. Your problem will be solved. |

Kerr Lake Fish Help me do a little learnin' here Wondering what you base your statement on since you give no explanation to go with it. Didn't know if maybe you're a psychic or you're just keeping secrets about why it's failed. If I was having this problem, I'd be looking for an explanation before just running out and spending some money on a new module. KenO |

Lots and lots of experience with my Fish and Ski Nautiques
I've spent several hours speaking with the technicians and two of their recommendations are in my post above; verifying 12vat the coil and ensuring a good ground. A third would be to get a good low resistance coil (0.6 ohms or so, like the Flamethrower) I've also encountered the exact symptoms with both of my boats, jumped through all the above hoops and it is always the Pertronix. Always. |

Now if you'd said that in the first place it would have been a much better post
Does TFreeman have an ignitor or an Ignitor 2 ?It doesn't show up in his pictures, just the wires leading to it. You might find different coil recommendations for each in the instructions like a 0.6 ohm coil for the Ignitor 2 and a 1.5 ohm coil for the original Ignitor. |

It is apparently an ignitor. Since the previous owner installed it, I'm having a bit of a difficult time locating an instruction sheet to double check things. I have noticed that the resistor (?) was not bypassed by the PO, and who knows what else he did. I'm almost tempted to order the kit from nautique parts that replaces everything. If I new it would solve it, it would probably already be in the mail. The compression test found nothing significant so I'm at least partially happy today |

The original ignitor has a BLACK module mounted to the plate
An Ignitor 2 has a RED module |

Definitely an ignitor it's got the black module and says ignitor on it (hahaha)

It wouldn't have taken several hours to watch a youtube video on how to install points and learn how to set dwell!! |

Problem solved... Turns out it was the float level actually causing a fuel starvation. A free fix. I feel kind of silly honestly. When I saw that the timing was not staying correct, I had completely ruled out the fuel system. I went ahead and swapped in a new distributor and the rest of the ignition system also before solving it today. Needless to say i have now been through this boat pretty thoroughly and it has gotten a serious tune up. I've got at least another month of HOT summer weather here (if not more) so I'm thrilled to have it running right. I appreciate all the help and knowledge shared in this thread. |

Well, good for you
After all that it looks like your Pertronix wasn't the culprit. I just put that here for all those Pertronix haters It ain't always the problem Your old distributor did appear to have some wear in the advance mechanism, so a new one was a good idea even if it didn't solve the problem What did you put in for a distributor?

Probably another Pertronix! Trevor, Glad you found the problem. Now it's time to get some time in on the water. |

You forget Pete
Pertronix doesn't make a 351W marine unit with the RR gear so I'm thinking he got something else |

I put in the kit from skidim. I will be keeping all the old stuff as spares just in case.
http://www.skidim.com/PROTEC-RETRO-KIT-DIST-RH/productinfo/RK107026A/ We are about 20-25 minutes from the nearest ramp so it's easy to make a trip after the wife gets off of work during the week, my full time gig gives me plenty of days off and my side business is slow right now so lake time should kill most of that down time. |
