I'll find that speed sensor an replace it.
Here's another "clue" about the issue I'm having. Twice the truck has died while driving. Flat out shut off for half a second then kicked back on no problem and once the trans slipped while downshifting into second when I got on the brakes. |

it will or should have a speed sensor in the rear end of the truck on top of the pumpkin, its probably a 15.00 dollar part. it tells the computer when to shift and if its sending mixed signals it will throw off shift timing and cause slips....normally.
it still does have a lock-up converter in it and whenever possible you should tow in the unlock up mode which would be 3rd, in locking it will hunt for the right rpm and you are not using the torque converter to its advantage. thats a first thought on the speed sensor, you gotta keep oil in that thing |

Speedo has been accurate and no weird ABS light but I'll keep my eyes open for it. No tow mode. Trucks a 95 f350 diesel so before the days of tow mode.
I've had nothing but terrible luck with this truck and I keep pouring money into the stupid thing |

4th gear is actually converter lock up, so you are using more of the oil supply to lock up the converter and that means less to the cooler circuit, do you have a tow button?
I have had the speed sensor go goofy in the rear end and it would cause very similar problems as to what you are describing, have you noticed the speedo going goofy or the abs light coming on intermittantly? |

95000 mile oils not burnt, was low but no apparent leaks. First time it slipped was 4th gear going up a hill on the highway with my trailer and empty barracuda behind it. Maybe 2000lbs. Did 3 fast slips in a row before I let off the throttle for it to catch. Otherwise it's done it mostly in second gear with no trailer on the truck. Has slipped maybe 6 times in the past week.

yep, was just talking to one of my guys about his yesterday.
when and where does it slip, how many miles? is the oil burnt? what else can you tell me? |

Thread Hijack- Eric, I know your the guru at rebuilding these transmissions are you equally well versed at E40D transmissions? Mines slipping after my trip to the CT mini reunion

26 pages, and not one of the transmission, without the transmissions these boats wouldnt be going anywhere, i was just wondering if their like the kid you never wanted, the blacksheep.

Yes, we used it as an extra levelling jack, that's why you couldn't see it Seriously, that motor box is looking good Tim. Nice work there. Taking a sawzall to a perfectly good motor box must have taken some nerve. I had a hard enough time just drilling my bimini mounts. The customizations you guys are putting into this boat are truly amazing. Thanks for dragging it up to the lake so we could all get a glimpse. -Brad |

Eric, Sorry if I missed it but what's the question that requires reading 26 pages?
If you haven't noticed, Tim is defiantly "Mr Prop" so I'm sure he has a plan!! Tim, Yes, what is the plan? Original prop to start but then see how it spins at a higher RPM? |

It's probably been mentioned but 26 pages is too much to search through for this question...
What's the plan for a prop? Same one you guys were running or are you going to have to play around with props till you find the right one for the added HP |

Bruce, the box wasnt (and still isnt) much to look at. We stored it out of sight behind Brad's camper! |

Thats awesome Tim! But from someone lucky enough to see the work in person (at last weekends CT gathering) these pictures don't do this boat justice!
Just remember if you need test dummies for barefoot runs I know 3 guys that are just minutes away ;-) |

Once again, we're overdue for an update. Time for a little bit of catch up...
To accomodate the wider exhaust manifolds, we had to widen the motorbox 3". The first step was to grind off all the gel on the inside, and then cut it in half: I took the wood out of the rear of the box that served as a backer for the hinges... it was rotten. I attempted to remove the wood from the top of the box, but it was solid (and dry), so it's staying. Next, I reconnected the top. And then the front and back. Now, Im in the process of strengthening the box, and raising it a bit. This will accomodate any future growth in height (intake manifold, carb spacers, etc). The front side in progress: I stole a trick from Roger and glassed around a piece of PVC... this piece will be cut in half and then glassed to the front edge of the box to serve as a small relief around the pylon. Ive seen this notch in Ski Tiques and Nautiques- not sure why the BFN didnt get it. Hopefully improving the clearance around the pylon will prevent the aluminum trim from further scraping it up. The back edge is already done... once the front is dry, then its on to the sides, and then the corners. In the meantime, we've been making progress on the engine and interior as well. Only the removeable front panels still need carpet- the trim is complete, as are the pockets, rear panel and battery box lid. I decided to try my hand at gelcoating, so after a conversion coat of vinylester, the battery box lid, driver's seat pedestal and rear panel all got several coats of gel brushed on. The gel was great to work with, though completely different than the epoxy. The opaque gel covered great- I will definitely be using it in the bilge on future projects. The brush marks didnt lay down perfectly, but its good enough for the underside of the lid and rear panel. Ill probably spend some time sanding and smoothing the pedestal. We ran the wire harness and bilge pump lines, and connected the exhaust hoses. Clearance was tight to the panel and motorbox, so we added some 45 degree SS elbows to help make the bend under the floor. We finished all the work at the transom- connected the speedo lines, wired the light and fuel sender, connected our gas lines and installed the tank. Dad also put a lot of work into the cooling system- all new hoses and clamps, new 'stat housing, etc. He also rigged up all of the new control cables and brackets and installed the new battery cables. In an attempt to "pretty" the boat up as much as possible before last week's CT get together, you'll notice we also installed the pylon, steering wheel, and shift knob... hopefully Joel is pleased! Last night, we cranked the motor for the first time since 2009 and broke in the cam. Other than a few small hiccups, everything went well. Now we need to break down the valvetrain and reinstall our inner valvesprings. Once thats done, theres little keeping us from doing a water test... so it wont be long now! |

That was going to be my guess. Not that there wasn't any progress, but that now that we're on the home stretch, we'll be waiting on the official "reveal" ideally well timed for 6/11. (give or take) |

We've been making progress, and Ive even snapped a few pictures... but theyre all on dad's camera. We're shooting to be on the water in 2 weeks- but it'll be tight!

You are correct Tim. That is exactly why MC put the dent in the hull on their powerslot. It was also to keep water channeled around the rudder and prevent transom slip for improved tracking as I understand it. That freaking dent was huge on that flat hull. Nothing like what you guys prepped for if necessary. Nice planning Tim.
LOL....I suppose to get technical there isn't a centrifugal force but there isn't a zero either. |

Matt, a tunnel wouldn’t work that great on this v-hull. The keel is too narrow- its only 3-4” wide. The TSC2 and TSC3 196/206 with that design feature have much wider (6”+) keels. If prop clearance becomes an issue, we can notch the keel aft of the strut, as discussed here:
Keel Modification We added fiberglass to the inside of the hull in this location, just in case we wanted to make this modification later on. Only the first 2 years of the BFN (79-80) didn’t get the notched keel- all 81-90 BFN’s had it. This allowed them to run 14x14 props, whereas our boat originally had a 13x15. As far as altering shaft angle, a simple hull clearancing near the prop wouldn’t help this. That would require a strut and shaft log change, at a minimum. The BBC and 72C tranny are already within ½” of the hull, so theres no room to be gained there either. Jeff, Mastercraft did the same as CC on their hulls to accommodate the 14x18 prop they ran with their 1.5:1 Powerslot transmission. It only looked special on those boats because the hull was otherwise flat. To my knowledge, it was only a prop clearance modification- not a wake shaping one like the TSC2+ 196. The 86+ PS190 hull did not have this notch, despite having the same ‘slot tranny offered… they got a little smarter and designed the hull and shaft/strut/prop geometry to accommodate the larger prop without a tunnel. Oh, and FYI, theres no such thing as “centrifugal force”. |
