I have a 91 nautique with electronic ignition. After it gets hot it will not atart until it cools. The large module for the electronic ignition at the rear of the 351 Ford gets extremely hot when this happens. Will replacing that unit solve my problem or is something else causing it.

Does the boat shut down on it's own or do you shut it off and it won't restart? ------------- Work to live, not live to work. |

That is the protech ignition system and not just a module and if it is getting hot then it's junk and you need to upgrade to the dist conversion PCM/SKIDIM sales. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

To 79 Tique,
After it has run for awhile it will sometimes shut off. At other times it won't restart after I have shut it off. Skiwoods |

Jack, My understanding of the Pro tech is they are nothing but a big problem! Chris (79) is correct that you should convert it. Parts are no longer available. Here's the conversion: http://www.skidim.com/prodinfo.asp?number=RK107025A - Pro tech conversion ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Skiwoods,
I don't know much about the Protech's, but I'm thinking this could be as simple as a bad coil. My 94 had the protech system converted out before I owned it. Unless there is something about the protech that would suggest other wise I would try a new coil first ($20.00). ------------- Work to live, not live to work. |

While the problem very well could lie in the coil, the Protec doesnt utilize a standard coil. It uses 4 coil packs, which are NLA. Youre only bet is to find them used from someone else who converted. ------------- |

unlike GM's system where you can replace the packs on the protect it's straight up replace the whole unit, same deal on the early buick units in cars. It contains individual coils that are in one potted assembly, module and all, typical of motorola's design so this makes it non-servicable and makes it a tosh the old and replace with new no in between. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

| Personally, I would contact Vince at SKIDIM. He is very knowledgeable about the Protec ignition. He will certainly help you troubleshoot. It has been a couple of years ago, but, I thought he told me he could still get coil packs or still had some. I could be full of BS. |

I have a '91 Nat. Excel with only 240 hrs. I have the same problem where my boat shuts down to 2500RPM. I gues that I will have to change the Protec over to the Retro Kit. Does the Kit come with instructions? If not, has anyone done the conversion or is it to complicated and should I bite the bullet and take it to a Dealer?
Any help would be great. Woodyz ------------- Woodyz 91 Excel |

Billy: I heard that you have talked to my son. I figure you and him can speak the same language. He had lots of good stuff to say about the conversation. Thanks for treating him right.

Stan Farrell,
I didn't fix the problem yet. Had some personal issues last year. It is the Protec ignition system which replacement parts are no longer available. You can get a replacement kit from skidim.com for about $400 plus which I have been assured will fix the problem. I have been told lately that you can get a kit from correct craft but I haven't verified that. Good luck and hope this helped. Skiwoods |

My 93 would sporatically shut down to limp mode as well. I checked everything but the answer in the end was a bad oil pressure sending unit.
You can bypass the temp sensor and the oil pressure sensor by leaving the wire unconnected (I think it was open, not shorted). If you do this you do leave your engine unprotected, but for trouble shooting it helped me out. The gauges are off of different sensors so the dash will look fine but the input to the module makes is think the engine has a problem, hence the limp mode to get you back to the dock. It would idle fine but if you tried to crank it up it would stutter like half the plug wires were off. The only way to clear it was to turn the key off and back on. Nothing on my units got hot but the local dealer did have a used coil pack and module on the shelf that I used to test. Once I eliminated the pack, I switched to checking the sensors and found it by process of elimination. A check of the sensor with an ohm meter showed it had like 10 ohms to ground when the engine was running. It should be basically infinity or an "open". ------------- 93 SN |
