That is a sweet Century, I would not have thought about putting the turbos between the manifolds and the elbows I like it. Wouldnt do that to a ski nautique, but I like it on the century.
Chris, I am considering all options at this point for the 351, from stock and buying a long block to absolutely not stock and completetly a$$embled by hand. Rotation direction, displacement, transmission upgrades they all roll through my mind. Money is not too much of a problem if I do it all myself, although leaving enough for a tower and another set of stereo upgrades would be good. My main worrys are reliability and keeping gas use somewhat reasonable, I will have 150 hours on the boat this season and it didn't hit the water till mid july and the weather hasn't been good. In a nice summer like last year I peppered 350 hours over the various boats (not including the sailboats, canoes, or jetski). I keep coming back to trying for a full roller setup, probably because of the week I lost this year to the flat tappet cam failure (even if it was my fault). I just haven't found a way to make that work out for me in reverse rotation.. still researching though... |

joey, i almost have this guy talked into selling this 5.8 ho boss engine for around 2500.00 it is a normal rotation engine,
i believe the rating is 285 at 4800, i keep pushing this engine cause it is a great deal, i talked to dim and they want 3400.00 for the long block alone. this motor has about 215 hours on it. if you are interested give me a call |

Jimbo and Joe I would be looking for a 1.23:1 tranny to use with those STD rotation strokers don't have to worry about the lean that way.

Yeah thats why I was asking about engine mounts and bellhousings. Eric I have considered that pro boss as a drop in and run it option, problem is I am not very good at dropping in and running anything. If it can be upgraded for some reason I can't lay off it. I would really like to end up with a RH prop on this one, but a reliable 350 hp could probably convince me to live with the lean.

well if I go to a 1:1.23 then I will have two extra BW 1:1s for trading purposes maybe I can use them to offset the cost of the transmission upgrade. Just wondering what the change in angle is going to do to me, anyone out there have a 1989 2001 with a 1.23:1 they can take pictures of?

Joe, what exactly are you looking at? I doubt much changed between the '89 and '90. I believe they even use the same motor box shell to accomodate the invertaflow muffler.

joe, i have alot of different stuff laying around including mounts, bellhousings etc..
I also will do some horsetrading for the 1.23 for the borg warners, figure out exactly what you want to do first, figure out chevy or ford, if i was starting from scratch i would go chevy,(hopefully no feelings hurt) you could easily put a stroked motor together for around 1500.00 to 2000.00. i boght a eagle stroker kit for 699.00 which came balanced with crank, rods, pistons, rings, bearings and i believe it came with the harmonic balance. that thing made all kinds of power and torque |

TRBenj,
The 89 is essentially the same hull as my 83 and came with the 1.23 so I wouldn't mind seeing motor box clearance, prop shaft length, bell housing type, type and position of mounts, coupling type etc. Some of that would be the same on a 90 but not necessarily. The 83 isn't even my project inboard at the moment so I don't want to get into anything that won't be done and broken in by early may, searching for something unexpected at the last minute would be not good. Eric I am just in the planning phase probably be another month before I decide and start to order parts and get things machined for an early spring build up, I am in middle of installing a new engine in the jetski right now and the wallet is still a bit warm. If I went chevy I am on the hook for new rwp and bracket, alternator and bracket, timing cover and circulation pump, exhaust manifolds (might buy something nicer anyway), new starter, new bellhousing, new marine fuel pump, new mounting brackets, flywheel, etc Probably enough parts to make the extra money on the ford parts worth it. And so it begins |

Joe, judging from the pics in the diaries, I would say that there should be no difference between the '89 and '90. I seriously doubt CC would have introduced the the new motor/tranny in '89 if they would have had to re-engineer the entire mounting system a year later with the introduction of the new hull. The '89-94 motorboxes all appear to be the same, which is a little different from the 82-88 2001 style. Here are a few pics:

Great find, Larry! Somebody has to grab that. Wonder if it would mate with the Borg Warner transmission? Put an ACME 540 on your boat and enjoy the ride!
Tim B., that engine matches your boat. Go for it! Ken |

That motor is enormous. Think it would fit under a Nautique motor box?

I previously owned a 2001 Air Nautique with the Python motor in it. It was rated at 425HP and it did move out. Fastest I ever had it was 55mph on the perfect pa$$ speedo.
There is also a new Nautique on my like from time to time that is the supercharged limited edtion that CC relesed and it sounds awsome coming out of the hole. |

Tim, you're a handyman. Maybe get a BFN engine cover? We'll get your '90 doing 60+ in no time.
Hey, Hollywood, maybe that's a great solution for your boat. You'd push the 40MPH mark with that big monkey! Matches your color too. Ken |

Hope that little girl stands back if they fire it up...she might get sucked right into the intake.

Yes it matches my color
![]() ![]() Maybe Alan can use it for his BF project if he picks up that one with the small block? |

there is a supercharged nautique on my like from time to time. Sounds great at idle and coming out of the hole. Almost sounds like a big block.

CC did manufacture a nautique with the ford supercharged motor in it. It was at the boat show here in michigan. It was hooked to a ford lightning because that was the only truck Ford made with that motor.
