If you’ve been following along as Finnegan and Newbern thrash on projects, you know that the giant Hemi headed big-block twin-turbo jet boat has been fun but also a bit frustrating. The thing runs great, makes stupid power, and Finnegan has got a handle on the tune, but the problem has been that the boat runs out of water pretty quick and can’t accelerate for long enough to actually make a full drag boat pass. If you can’t get enough water into the jet pump to keep it fed, then it cavitates and stops pushing the boat forward. There are a few ways to get more water into the pump, which Finnegan has gone over on a couple of videos, but while each adjustment has made the boat better, it just hasn’t gotten it working well enough. Until now.
Yep, they’ve made some more adjustments and they are finally all working together and this thing is starting to haul ass!
Unfortunately, those adjustments required a grinder. As if the hull didn’t have a big enough hole in it already? Jet boats have a giant hole in the bottom of them, which is a little un-nerving when you think about the fact that holes in boats are usually not a good thing.
Mike will explain, so watch and enjoy.
