All I'm wondering if anyone can comment on what gas I should be putting in my '83 SN. The guy I bought it from said to only ever use non-ethanol fuel, but the first time I filled it up I couldn't find any around me so I used 93 (possibly ethanol) fuel. So two questions: 1) Does it matter? 2) If it does, should I be worried about letting the current possibly ethanol fuel sit in my tank? Should I try and use it up ASAP? Drain it some other way? Should I bother using something like SeaFoam to clean out residue? Thanks! --Chris N. ------------- "Two rules, kid - ya gotta want it, and ya gotta give'r." 1983 SN |

Also - I know mine has a new carburetor; will that affect anything? --Chris N. ------------- "Two rules, kid - ya gotta want it, and ya gotta give'r." 1983 SN |

Use what you can find. I try to run the non-oxy if I can, if I can`t find that I try to run Premium Unleaded. ------------- 1976 Ski Nautique 351 Escort 1984 Barefoot Nautique (Parting Out) |

| E10 is all you can get here, so I run it exclusively. Doesn't last great but burn it in a few weeks and you're fine. A stock 240hp PCM 351w may run just fine on 87... 89 is recommended per the manual. Premium is a waste and may not run as well either so I'd avoid that (lose/lose). |

Might be a nice winter project to change out the rubber fuel lines especially if they are the originals and clean the anti siphon valve, the ethanol likes to eat at the older rubber lines. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

I've used ethanol since it came out. Never had a problem even over winter layups but do stabilize it for the extended storage. ------------- /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 < |

I'm on the water 3-5 days a week 13 months a year and use strictly 87-89 ethanol. No problems with carb nor efi. If it sat for 3+ months I'd shy away from ethanol if possible. ------------- Please support The Cystic Fibrosis Foundation 1976 Ski Nautique 351 Escort 1993 Ski Nautique purple and black 351 HO PCM |

I ran 89 E10 in my 78 for years with nary a hitch. The only exception was the last tank of the year I would fill with 93 non-ethanol with stabil after I ran it empty or as near as I could. I would take a few runs with the ethanol free gas before putting up for the winter. I never ran it dry or drained the carb for winter layup and seemed to do well. The first 15 years it was a stock 351 240hp, the last few I had GT-40p heads which probably added a point to the compression and even then the 89 octane worked well. I agree with changing out the fuel line, I doubt they put much thought into ethanol in the fuel in 83. ------------- JJTaub 78 Ski Nautique-past 94 Ski Nautique |

My 89 has a label near gas filler warning not to use gasahol. Like others said above, if you modernize the fuel lines, etc, should not be a problem. ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |

But you lived in those day's. No one in their wildest imagination would have thought they'd take perfectly good corn squeezing's and make alcohol for your vehicle's tank. Your tank yes,your car nah. Speaking of which,gas here went fron 2.19 to 2.55 overnight. You'd think a holiday is coming up or something. I guess I'm supposed to be more concerned about some statues somewhere. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

Fill it up. Go to the lake a lot, ski, ride and enjoy so much that the gas does not have time to go bad. End of season last tankss lots of Marine Sta-Bil and run until it is in the entire system. ------------- FGroce 88 Ski Nautique For 28 years Now 2002 Ski Nautique |

Last time those boats were run where probably before ethanol hit the market anyway! ------------- "Morfoot; He can ski.

The first day I had my 1980 SN, I put regular gas in it. It ran like crap after running great for the lake test. For then on, I always put in Mid Grade and sometime premium. It ran so bad on regular I never did that again. ------------- 1980 Ski Nautique SOLD Back to Cypress Gardens 2002 Sport Nautique, GT-40, FCT2, Cover Sports, Tower Bimini, Inc., Wet Sounds Audio System, Star Gazer Wake Edition S. 1968 Ski Nautique, Project. |

I have used regular when filling up at the gas station. Didn't realize I was supposed to be using mid grade. I sometimes fill up at the lake, not sure what they use. I have noticed hesitation sometimes when filling up as the gas station. What are the symptoms of using the wrong gas? ------------- 96 Super Sport Previously: 95 Sport Nautique, 1980 Ski Supreme |

Too low of an octane rating and you will likely experience detonation or "pinging". My experience in the petroleum industry is that many low grade gasoline (with or without ethanol) is just that: Low Grade Gasoline. MTBE and BTEX are common gasoline additives and they don't burn as clean as straight gasoline. Ethanol, MTBE and BTEX are often added to the lower grades of fuel as an octane booster. Too high of an octane rating is a waste of money and produces more emissions than the correct octane level would normally do. Some people think that their engine will perform better if they use a higher than specified octane rating. Not so. Go with what the engine manufacturer recommends. For engines with electronic fuel injection, many have "knock sensors" that are designed to detect detonation or pinging. Typically, when the knock sensor detects detonation, the ECM will then adjust the ignition timing to mitigate the detonation.

All true as stated by Jonny Quest but not stated is when the computer senses detonation and pulls timing out of the engine it leaves you with less power and that could be at the same time you really want power. Knock sensors can save your engine from any detonation damage which is fantastic but with a higher grade of fuel you would enjoy full power and not trigger the knock sensor to pull timing back.. I am not talking of jumping into race fuel and 110 octane. Just a jump from 85 to 87 or 87 to 89. Maybe in the extreme from 87 to 91 octane. Sometimes one bump up keeps you at full power. I run plain entry level gas in most of my cars and the boat unless I know I need to upgrade. If you have to adjust your timing to eliminate pinging and detonation you are detuning the engine and leaving some performance on the table. I try and avoid ethanol blends in all my engines even though I know guys that have tuned for it and race with it. ------------- |
