| We've got a 2000 SN 196 with a GT 40. Been running well ,put a new fuel pump in last summer and has been good. It has about 850 hours on it. I'm contemplating up grading to a 2003 SN 196 650 hrs, it has the same hull as the 2000 SN 196 but the PCM chevy engine ( I think). My question is is it worth it to get into this boat out of concern about the GT 40 having issues ? Or would it be more of a lateral move.? Thank you for any thoughts on this. Charlie in VT |

Not the same hull (TSC2 came out in 2002, 97-01 = TSC). An improvement in slalom wake, reportedly a regression in trick. That could be addressed with a hydrogate addition though. I wouldn’t worry about the GT40 longevity though. |

Would love to see your expression when you find out that Chevy motor has been discontinued as well  ------------- 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 |

| Thank's for the hull correction. And thoughts on GT 40 . Probably end up keeping it for a while ,good used SN196's are few and far between. |

There are a few GT40 owners that are stocking up on spare parts like ECM’s, distributors, thick film sensors, and other misc parts as they become available. There are engines with over 3000 hours out there still running. If you take decent care of the boat in and off season I see no reason to trade boats to get different engines. |

my 5.3 truck engine has 8300 hours. No reason that a gt40 wont do 3-5000 if you maintain them which I do mine, mostly overkill. Oil changes after a 37 hour season. Am I wasting my money on 40wt oil? yes! Do I care? NO ------------- 1979 Calipso Runabout (the boat that got it all started) 1988 Mastercraft ProStar 190 (sold) 2000 Pro Air Nautique/GT40 |

I look at boat engine service in the same way I look at aircraft recip service. Road vehicles spend a significant amount of time at low load and that’s why you see 8300 hour engines. That’s probably way out of reach for a boat or plane engine due to the near constant load (with the exception for boat owners who idle around the lake endlessly and rack up hours at zero load). Tach time would be interesting for boat engines. I wonder if Perfect Pass could yield that sort of data. |

| I made the switch from a 1997 SN to a 2004 SN 196 seventeen years ago. Trust me you’ll be happy with the 2003. Slalom wake is slightly better and the Excalibur is a fantastic engine. For the record all non CAT engines have been discontinued but ski dim has enough spares to last me forever and they’re very close to my home. |

No GT40 parts crisis here... spare ECM, recent disty and thick film from the local auto parts store. Approaching 1600 hours.. ------------- Current: 1997 Nautique Previous: 1987 Nautique 1964 American Skier |

It’s the marine specific components that I would want to store up on. If I had an FCC, I’d want to have a spare setup. I forget what else but maybe the marine distributor. I think someone will step up for a profit to supply parts for many years to come. |

It must be southeastern New Hampsha' slang for distributor and TFI 4 ignition module  |

"The Thick Film Integrated Ignition (TFI-IV) name is proprietary to Ford. Others may know it referred to as a "spark module.". Back when Ford was using their EEC-IV engine control unit, it was coupled with a special ‘TFI’ module designed to control spark output via information attained from the EEC-IV control unit." ------------- /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 < |

... there's a reason Ford called it EEK-Four! But I digress... a spare FCC isn't a bad idea.... although anything can be fixed one way or another..... Ok, that statement is from a guy that built a Jeep with a Chevy engine, Ford transmission and Jeep transfer case... And a Ford Cabover on a Dodge chassis with a Corvette engine and Chevy truck transmission... Maybe I'm not the best person to ask...

| As much as I loved the power of the GT40, the technical wizardry that requires a 300 plus page manual always made me nervous. |

If you need a ecm, I have some for sale. Ive always found any parts that I've needed for the gt40 engine were easy to find at the local parts store. |

I might be a little suspicious of Mikey since he's hit about every website he can think of that has anything GT40 related with posts telling things like "I needed a gt40 ecm and I got it at gt40 marine.com or (gt40 ECU.com) as it was previously named" as one example. Doesn't bother mentioning that it's his "business" Or "I need a gt40 ECU, has anybody used gt40 marine.com?" to get some free exposure Pretty easy to do a search of his posts in different places His techniques leave more than a little to be desired He's not exactly upfront about anything. His old posts here on CCF might tell a little about the way he does things too. All just my opinion of course

IMO a move to a 2004 from your 2000 really makes no sense. They are both really old boats at this point and you're trading an old boat you know for an old boat you don't know. Many would argue that the TSC1 hull is the better hull all around anyway so that might be a regression. I wouldn't particularly be worried about the GT40. These aren't like an outboard where a new outboard is $30K, these are pretty basic car engines and reasonably priced in comparison. A new interior or trailer are worth more than the motor. What you're going to see as time rolls on is folks swapping out their GT40s for new motors and Zero Off speed control because the TSC1+ hulls are still such damn good boats in all ways even by modern standards. That's going to leave a steady stream of GT40 parts and long blocks for years to come IMO. We've owned our 2000 for (unbelievably) 15 years now and it's 21 years old at this point. I'm sure I'm shooting myself in the foot here but knock on wood no big problems so far with our GT40. When it dies I'm putting in a new motor and Zero Off. Not worried about it.

Correct me if I'm wrong (why am I even bothering to say that here?) but doesn't an '03 also have an FCC? No advantage then, to have an Excal over a GT40 as far as that's concerned. And yeah, a spare FCC isn't too far down my list of crazy things I'd keep in stock for my '03 with the Excal.

Curious why you need a complete FCC, wouldn’t just having a spare pump be enough? ------------- 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 |
