+1 on a ProTech system failing. Time for a new Davis Unified Ignition HEI distributor set-up. |

Well I think I may have found the problem. Today I took the dyne out. Whipped around a couple laps, it then began to sputter at 2500 rpm in limp mode. I pulled the wire off of the protec oil switch and water temp switch. Shut the engine off to reset the computer. Fired it back up and whipped around the lake again. Never went into limp mode. Ran perfect the whole time. Plugged back in the water switch and it ran perfect still plugged in the oil switch and it still ran perfect. It seemed to idle and run better overall with the oil switch dissconected. The post on the oil switch was very loose and felt broke. I think that was the problem, for now anyways. I'll order a new switch from skidim and see what happens.
Save 500 bucks if it goes well. |

Thanks! That's what I was thinking. Save a couple hundred and go with the risk. He says it works great and all boxed up ready for me already!

the generic answer is that you would most likely be buying a used item and therefore buying something with a shortened life span. But that is also relative as used items could still last forever (or outlive the thing they are going into). You won't know until you do it. At least with a new item, there is a greater potential to rectify a problem on someone else's dime. To me, I'd take the risk from CL at the price you quoted above. If you get a year out of it and it fails...you aren't out that much. If a used one was only a couple hundred less than new...i'd get new.

After reading about protec problems, and how common they are. I'm pretty convinced that is it, especially because it only does it sometimes. I will look into that tho. Thank you
I think I'm going to buy the used kit from Craigslist, any reason I. Shouldn't? |

It's worth looking into, but since it sounds like it runs normally at idle and there's no indication of white smoke, I'd say the likely culprits would be ignition, fuel or fuel\air mixture. |

Also sounds like water in the gas. would rule that out as well.

It is not the protec system, and it is left handed, same as mine. Normal distributor with coil and ballast resistor plug wires and wiring harness

Probably not. It'll either have the same problematic ignition system or one with a gear meant for an engine with the opposite rotation as yours. Most likely the former, in which case I wouldn't pay $5 for it.

Did Mullin's RH scrappy come with ProTec? I know he changed distributors after ownership.
I'm guessing the 240hp RH engines got distributors [QUOTE=SneakyPete">I have a 93 Ski Nautique Standard with a RH 351 and the 1:1 tranny. It does not have a protec. |

Randy in ohio could probably tell us... Pretty sure he has a RH 1:1 proboss/protec in his '93 Sport. |

you're also going to need new wires as well. I'd say spend the money and get a whole new set-up (wires, dizzy, and coil). Don't waste time with used stuff from eBay.
It should cost less than $500 if you install it yourself. Skidim has a replacement kit Here We also get a discount for being a CCFan member. Should help with the cost. |

what i ment was the good option is probably all i need.

Definitely too many epoxy fumes over this way... there probably isn't such a thing as a RH protec in any boat

I have no reason to believe his 94 Hydrodyne is not a LH engine.
Post up the engine model number. Starts with a P. There should be a black and white metal tag bolted on the top of the engine. |

Ebasic power shows a couple options in RH for distributors from 190-360 - you will also need a matching coil and maybe a ballast resistor depending on your choice. Don't throw away the gear on the bottom of that distributor type thingy yet until you find out if the RH options are actually available.

Yes. That goes in the garbage and a distributor gets installed.

ill have to gracefully bow out here. I have no clue with that setup. but im sure someone else does. I'm intrigued though. Is that like a coil for every two plugs?

Yeah that's a protec setup, its going bad and very likely the cause of your issue. A new ignition system will probably be your best bet. Do a site search on protec ignition failure or replacement to learn more.

here are the pics! LOL every one loves pictures.
it doesn't seem like there is any advance mechanism under the disturber cap. so posiably whatever advances is going bad? |

lol HW.
pipeline: I just mean, test the spark coming from the coil, then test the spark from each plug wire, then test the plugs themselves. The spark should be the same along each path. For instance, when I was testing my ignition, we did each wire, then the plug on the wire and when I got to #5 wire it was similar, but the plug had a different spark. replaced all the plugs and was back on track. |

same issue that started this thread. it seems to be happening more often now and i would really like to fix it.
carb was brand new as far as i know. ill check how fuel looks, i think im just going to go ahead and change out spark plugs what do you mean by check the pipeline of spark fom coil to plugs? |

Is this still the same problem that started the thread or did that resolve and this is now a different issue? Pics would definitely help.
Have you checked timing? are the advance weights moving or are they stuck? After that, check the pipeline of spark from coil to plugs. Though it might be redundant to check spark from coil, pretty simple to rule it out.
how does the fuel look when squirting into the carb? was the carb brand new, rebuilt, crusty junk pulled off the shelf? |
