Hello Everyone, This is my first post on CorrectCraftFan.com, but I have been using the site for over a year now; what a wealth of information! I purchased my 1973 Ski Nautique at the end of the summer last August. It ran alright, but had been sitting in a driveway unused for about a year. In December, I tore the boat apart and replaced all stringers and flooring. I also had the Edelbrock carb rebuilt this spring as well as had the exhaust hose kinks fixed with new stainless steel elbows. The boat starts every time on a dime while on the trailer hooked up to a hose. Last weekend, we took it out to the lake for the first water run of the season after the overhaul. The boat started and idled around the dock just fine for around 5 minutes. Once the truck was parked, and everyone was on board (3 of us), we made our way past the buoys, I gave it some gas. At first, it went fine, but huffed and puffed, and the motor died. The boat would not start again, and we had to get towed. We finally got the boat on the trailer and out of the water. I turned the key, and the boat fired right up. We then placed the boat in the water on the trailer. It started again, and I placed it in reverse off of the trailer. The boat died again and would not start until out of the water. We tried a third time and got the same results. The electric choke has full power and is working fine. The prop shaft also spins freely, so I don't think there is an alignment issue. Any thoughts? It's as almost the boat doesn't like water! Thanks Again, Ben ------------- Ben P. 1973 Ski Nautique Kansas |

Welcome to the site & congratulations on getting your boat overhauled. I would narrow it down to ignition vs. fuel. I assume you have the timing set correctly. Run it on the trailer at the ramp to see if you can get it to act up, use reverse if power loading is frowned upon in your neck of the woods. Once it acts up, check to see if the coil is hot. Maybe pull the coil lead & check spark. Also see if the carb has gas (take off arrestor & have someone pump throttle - look for stream of gas in throat). Good luck, let us know what you find. ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |

Like Chris says... could be "A" fuel "B" Ignition "C" All of the above (or a combination) When it dies, .... did you check the carb to make sure it's squirting fuel? ..... make sure your dizzy weights are advancing when under acceleration? .....what do plugs look like? (wet, carboned ,etc) How old is the fuel in the tank? Have you checked the fuel filter(s? What do you have for gas lines on the boat? Do you have pics of the engine? (and the rest of the boat? ...we like pictures!) ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1117&sort=&pagenum=6" rel="nofollow - 64 American Skier 62 Classic.. 73 Ski Nautique |

Will it rev up on the trailer/hose when cold? I guess you could be flooding out but sure sounds like another hot coil! Do as the other guys suggested and check for spark and gas. You should be able to hold your hand on the coil. ------------- |

Going to try and put her back on the lake tonight after work, I'll be sure to let you know how it goes. Thanks Guys ------------- Ben P. 1973 Ski Nautique Kansas |

Sorry, and to awnser your question, it does rev up like nobody's buisness on the trailer when hooked up to the hose. When I put it in and out of gear quickly on the trailer, it runs fine. But, when I put it into gear in the water with the extra strain, it just dies. I'll check the coil out tonight. It is getting plenty of fuel and spark currently. ------------- Ben P. 1973 Ski Nautique Kansas |

also check your dizzy advance weights to make sure they're free. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1117&sort=&pagenum=6" rel="nofollow - 64 American Skier 62 Classic.. 73 Ski Nautique |

Vacuum Leak? Another test, use a level along the gunnel of the boat running front to back. How does the level in the water compare to the level in the the water? Wondering if it's possible if it's a fuel bowl level issue. |

If it won't run under load I'd have to do some research but still puzzled why it wouldn't start back up. When this happens you must verify spark and fuel before we can go further. ------------- |

It won't run under a load you need to check your firing order and confirm you haven't crossed a plug wire. They can run and sound surprisingly good without a load even if a wire is crossed but put a load on it and it will stumble. ------------- You can’t change the wind but you can adjust your sails |

If it didn't have the problem last year and the only thing done on the engine was a carb rebuild, that's what I would suspect. Unfortunately, it's an Edelbrock. I don't know squat about them. If it was a holley I would say to make sure the timing is set properly and then the idle mixture is set for the highest RPM in gear and idling and then adjust the idle RPM to 650 RPM. I have no idea what the Edelbrock equivalent of those adjustments are. If it has fuel runnning down the throat of the carb after it shuts down, there might be some float adjustments needed. Alan has a good point about the plug wires too. I've seen them run pretty good on the trailer or idling and then like crap as soon as you try powering them up. Although my personal experience in that regard is it will generally start missing and/or backfiring as soon as you try powering up. This is just dying instantly. A crossed plug wire wouldn't have any restart issues either. It would normally start right back up again. I guess it entirely depends on what wires are crossed in the firing order and if there is more than one. I say to look at the carb but somebody who knows Edelbrock carbs would need to chime in. ------------- When people run down to the lake to see what's making that noise, you've succeeded. Eddie |

I definitely missed the carb rebuild part. Yes, go back to "what's changed" from when it was running good. ------------- |

Hello Everyone, Thanks again for all of the replies. We found the issue! The wires on the oil pressure gauge were crossed. This caused the boat to ground through the prop with the water. This in turn caused the boat to run fine on land, but never start when in the water. We noticed that the oil pressure gauge was maxed out. When we unplugged the wire off of the oil pressure sensor on top of the motor, the boat started right up in the water. I went back through the wiring, and now the boat runs like a bandit. We just got back from a long weekend at Table Rock Lake in Missouri. I can barely walk from all of the skiing I did behind the boat. Thanks again for the help!  ------------- Ben P. 1973 Ski Nautique Kansas |

You know the history? tell us more. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1117&sort=&pagenum=6" rel="nofollow - 64 American Skier 62 Classic.. 73 Ski Nautique |
