I've been eyeing a new carb for my 89 next spring, as my current 4160 has seen better days. I'm leaning toward the Quick Fuel 600 cfm as a stock replacement to my 4160. Just wondering if anyone has any experience with the QF carbs. ------------- 1989 Ski Nautique 2001 |

Braden, I just used the site search (google would be better) and about 11 hits came up on Quickfuel just in the last 6 months. I'd provide a link to the search but I seem to remember they expire after a certain time. Lot's of good reports on the carb! ------------- /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 < |

Thanks, Pete. All of the threads I found were 3-4 yrs old. ------------- 1989 Ski Nautique 2001 |

Give them a call first and talk to tech guys. They are very helpful. You may want to go with a 650 cfm because of the mechanical secondaries, four corner idle screws, and different fuel inlet fitting. Totally different carb than 600. They will know what is best for you. They helped me pick mine out. ------------- Keep it as original as YOU want it 1978 Mustang (modified) |

Thanks, Duane- I'll give them a call. You don't think the 650 would be too much carb for a stock 351? ------------- 1989 Ski Nautique 2001 |

I have a QF M-600 marine carb on my 1994 SN with 351W High Output engine. I had to convert from Throttle-Body EFI back to carb and distributor after the TBI failed as parts for TBI and engine management control systems were NLA (no longer available). So, I went from TBI-EFI back to carburetor. In my opinion, the engine performance has not suffered one bit. The QF carb makes the boat feel like the TBI did when everything was working properly. The QF M-600 design is really what the Holley "should be". It is based on the 4160 but with many upgrades and features that are not on the Holley. Here are a few things on the QF that are not on the Holley: - Replaceable jets in the secondary metering block - Replaceable air bleeds for Primary and Secondary circuits - Float bowl sight windows - External float adjustment hardware - Superior metal casting (much better fit & finish) The Holley is a good unit. No debate there. The QF is simply a much better unit. Plus, it COSTS LESS!

For a stock 351, the 600 CFM is plenty. The QF 650 carb is a very nice unit, but it is about $100 more. Unless you stroke the 351 or modify it to rev up to 6,000 RPMs, the M-600 is really all you would need.

Personally i would choose the 650 for the mech secs, and the 1/8" larger primary bore, the latter keeps one entirely out of the secondaries at 36 mph slalom where a 600 vac sec one has to dab into the secondaries when compensating. The throttle response will always will be more crisp in that narrow transition point with the 650, by design, and the larger primary throttle bore will likely avoid it altogether. ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing."

Thanks for the feedback. I've tried calling QF, but haven't been able to get through to anyone. I just sit on hold forever. ------------- 1989 Ski Nautique 2001 |
