Twin-Turbo Jet Boat Rips the Water! Finnegan's Garage Ep.96 

Ganger 1,5 mill
96% 14 668 466

Our fourth lake test was a success! After troubleshooting the ignition and fuel systems that plagued our last test session, we finally got to rip across the water at 90 mph and there's plenty of speed left in this beast once we get the air/fuel mixture tuned perfectly and stop the turbos from trying to melt the fiberglass boat hull. This video has lots of tips about troubleshooting V8 engines and it ends with us having the time of our lives in Game Over, our twin-turbo jet boat.
Note: I live at the lake and nobody was near me when we tested the jet boat. We are staying away from people just like you are, I just happen to be fortunate enough to live in a rural part of Georgia. Anyway, thanks for watching and for liking and commenting on this video. We'll be back soon with another one!
If you'd like more information about the ultrasonic parts washer that we used on the spark plugs in this video then go here:
Game Over is a 2017 Peterson Placecraft fiberglass Jet Boat hull
It's powered by an aluminum 711ci Sonny Leonard Hemi with twin Precision 88mm turbochargers. It features CP pistons, Carrillo connecting rods and a Bullet camshaft. T&D shaft rockers and Manley valves and springs are in the heads. The engine and boat is wired completely using Wirecare.com and Techflex products. It runs on 118 octane Rockett Brand racing fuel. The efi is from Holley, the ignition is MSD and the jet drive is a Dominator pump built by B1 Racing. I welded the headers from a kit by Stainlessheaders.com.

Cylinders not firing? Do an oil change! That should fix it. Lots of money and little “mechanic-ing” skills would be a clue.

You guys wasted your time. The metal in the oil is normal for the break. And nothing related to the crank or bearings will cause misfire.

If you don't understand the basics all the electronics in the world are can help you . The boat is a turd . It's hard for me to believe this guys making videos that you're supposed to learn from . When he showed to the spoon directing water into the pump . That's totally wrong . Ron Hamilton the original owner of place craft . Knew exactly what to do . I saw with my eyes at High Point with North Carolina one of his boat go 175 miles an hour . Finnegans boat will never see that speed unless it goes off a cliff . All the old-timers didn't have all the computerized technology . But they went fast as hell . Can you imagine having spent this kind of money . In the boat misfires . Unused Fuel injectors don't go bad . Roadkill needs to stick with the junkyards .

Just a quick tip, When using an Ultrasonic cleaner to clean up plugs, ensure that no moisture gets into Centres as they will pop them out the porcelain and leave the steel threads in your engine block lol!!

Gday Finnegan, Man! Now that’s my kind of “social isolating”. Great job on the setup and all the best with the ongoing tuning. Just wondered what that “fat rooster tail” was at 21:26? Maybe a lowered pick up or trim tab etc? Nothing beats hammering across a glass-off in a big block powered boat! 🤤 We see you guys are copping it bad up there at the moment. Hoping it’s all over sooner rather than later. Our thoughts are with you, stay safe and well, Cheers from Oz 👍🍻

So I got a couple questions one of the neighbors get upset because you're driving a drag boat out on the lake? 2. does that lake have a speed limit law I know up in Minnesota you can only go so fast out on the lake otherwise the DNR can give you a speeding ticket. 3. Could you build a motor like that for my pontoon boat? That would be exciting.

My Dad told me years ago to install a strong magnet to your OIL filter (and pan) to hold any steel or iron particulates from going back out. (of the filter). I do it to this day....:) Change the oil and re-use your magnets !
