After nearly six years of construction, my 19-foot long Placecraft jet boat is ready to rip the water. In this video we finish fabricating, wiring and plumbing the 711 cubic inch Sonny Leonard Racing Engines twin-turbo Hemi and it roars to life. We also drop this brand new boat into the water to see if it's floats. This video also gives you tips on building battery cables, fabricating aluminum parts and how I used compressed Co2 aka Carbon Dioxide to control the Precision turbocharger wastegates as well as the shifter and Place Diverter adjustable jet drive nozzle.
As much as I'd like to make a fast pass in Game Over there is still a lot of tuning to do before this boat is safe. The engine has not been Dyno-tuned and we'll likely do that ourselves by driving the boat and making changes as we go. That takes time so bear with us as we take baby steps towards finishing this insane pleasure boat project.
Special thanks to the companies who build such great products that brought this project to life:
-We wired the boat front to back using nothing but products from Wirecare.com
-Holley.com provided the complete Dominator efi system including a touch screen, 160 lb/hr injectors (We will probably change those our for 220s), and data acquisition sensors.
-Stainlessheaders.com provided the hard parts we used to build our custom turbo headers.
-Precision Turbos build the custom turbos, intercooler, blowoff valve and waste gates
-B1 Racing build the custom jet drive
-Sonny's Racing Engines built the Hemi using parts from Brodix, Sonny Bryant, Carrillo, CP Pistons, Total Seal rings, T&D Rockers, Bullet Racing Camshafts, Accufab throttle body, MSD Ignition, etc
-Peterson Boat Specialties and Advantage Custom Boats created the fiberglass boat hull
-Chastin Brand lettered the hull
-Earle's Performance Plumbing provided the hoses and fittings
-Race Part Solutions provided all of the mandrel bent tubing and connectors for the cold side of the turbo system
-Odyssey provided the lightweight battery
Stay tuned for more videos about this awesome project as we explore the limits of this jet boat and my intestinal fortitude to drive it.

I have the same hydraulic wire crimp, got it from Amazon and it works great. But it does require printing off the convention table as it does not come in AWG.

Regarding the sacrificial water hose, you reminded me of an old Navy Chief I once worked for. As I was attempting to get a piece of electronic equipment mounted up on a platform about a hundred feet above the deck, it was after hours and there was no immediate parts support. Of course I needed a fitting to get the whole mess finished before we went to sea the next morning. I knew where to "liberate" the correct parts but the supply guys weren't on board... they had gone home hours ago. The Chief just smiled and said, "Son, you'll find in your Naval Career that it's sometimes much easier to ask forgiveness than to get permission." So be it!

Chesthair Ascot År siden
Man, well done on the wire harnesses. That's not easy or intuitive work.
Running a u-joint driveshaft with "zero degree driveline angle" is guaranteed to cause u-joint/driveshaft "failure" even without the additional "don'ts" of no "slip yoke" and no "torsional damping" on the drive end of the driveline. Additionally the "critical speed" of that aluminum driveshaft is nowhere near high enough to keep it from "breaking" before the engine "redline" and that pathetic little "safety loop" is in the perfect spot to "saw through" the driveshaft tube when it hits "critical speed" and starts "whipping".

i have these connectors in my boat for my dash gauges and buttons and i just soldered the wires in the pins, protects the wire from corrosion and then i coat the back of the connector with liquid neoprene. im not a fan of crimping bare copper in pins for boats, water vapor, especially salt water will find its way into every tiny spot and it likes copper very much. + i would never pay so much money for a simple crimp tool xD

I did not see a life jacket? Testing purposes only don't count in this instance, and if you had it on under your jacket, then I apologize. Be safe. After 6 years of love on the boat, and many many years of your entertainment in the world of hot rods, and mini trucks,, We'd hate to lose you to the water brother! Also, that boat looks huge until you sit in it on the lake and you and the engine are the only things to see, lol!

Why would you put a Sonny Leonard motor to a jet. You could probably go just as fast with a 383 with a can unless you spent a fortune on the pump. V DRIVE, V DRIVE, V DRIVE

He won't be ripping across the lake very far. That boat has nothing to cool the motor. If it has an impeller you need a new one cause you ran it dry as in no fake s lake. 😕

The difference between a real gearhead/car guy/engine builder/boat guy and Finnegan @ 30:38 Finnegan is watching his finger on the push to start, while a real enthusiast would be watching his engine/project he just built as it comes to life.

If you dont want the weld to crack later purge weld the fabrication to the turbo, plug one end of the tube and put argon into the other while you weld it.
