| Boat runs fine on idle, but hesitates and dogs down when load applied. Any easy fix ideas before taking into a mechanic? Smells like it is running rich. ??? |

Since I get easily confused on Pro Boss stuff, is this Fuel Injected or a carburetor? ProTec ignition or a conventional distributor? |

With the info you gave, it's kinda hard to give any kind of good answer without a better description of the problem but since it's a ProTec ignition system, there are plenty of people around here who will automatically jump up and say it's the ProTec system failing and recommend replacing it with a distributor, with the argument that if it isn't failing , it eventually will fail. It could easily be that you have fuel system/carburetor issues though instead of ignition system problems. Is the boat new to you or have you had it a while and this just came up? Can you give a more detailed description of what is happening? . |

| I don't know how much you want to invest - but my '93 SNOB runs amazing after replacing both the carb and the Protec. I have a new Holley along with the DUI distributor. CCF Forum was lots of help with the upgrades. Best investments I have ever made in my Nauti Gator. |

Hey, did you follow a write up or do you know if one, that shows pictures of what to leave and what to take off when going through this. I am a little lost with some of the instructions on the distributor literature. Thanks! Erik |

Bogging down is a typical symptom of a problem with the carb’s accelerator circuit. We need a bit more info for a better diagnosis. ------------- Current 2003 Ski Nautique 206 Limited Previous 2001 Ski Nautique Open Bow 1994 Ski Nautique Open Bow Aqua skiing, ergo sum |

I spent some time researching this site - there were quite a few detailed posts about the conversion. Jonny Quest was also very helpful regarding some specific questions I had. We ran it hard all day last Friday and Saturday and it performed flawless. I have the Davis Unified Ignition along with their "live wires". Last fall I set the old ProTech ignition in a box and its now completely stuck in the box from all the goo ozzing out of the ProTech. And I have a Holly carbed 351 with GT40 heads. I'm happy to help with any pics / info you need.

Jonny - one thing I keep wondering is why anyone would replace the original Protec with a pointless distributor and still have to run a coil and resistor? The DUI is self contained and was an easy install - I think 2 wires if I remember. |

And here I always thought the DUI had one of those things called a coil, mounted on top of the distributor cap  What are those other 3 wires that are associated with the DUI? They seems to have something to do with that big thing on top of the cap

That's true! I should have said "external coil"  Its compact and works well - so far so good! |
