Check those hydraulic seals on the skid steer! The time lapse showed some dropping forks while holding that table! Be safe boys

That looks cool 😅 I would def listen to the song “Dupe - Kontrolla” if I was driving that

The mini jet boat needs to be re-wrapped! Excellent video as usual! As a suggestion, when mounting the engines, use a single jet, with a chain driven drive shaft. The engines could point opposite directions, so the inlets are both on the middle and the exhausts to the outside.

Fireball is so damn good as well. Of COURSE Ethans is also a fan!

A wise man once said “make sure your jet ski tether is securely attached fellas 🤙” to bad I didn’t listen 🤷

Always love watching GrindHardPlumbing videos in a jet ski dirt bike would be super cool and even a jet ski quad runner

I'm such a 13 year old. Sitting here chuckling about homie saying that we really don't know how it runs until it has a load on it. Shit. Lol. Love you guys.

I like seeing Patrick still hanging out around the shop. He'd be a great addition to the team

That old dude you got the second ski from seems like he could have A LOT of stuff you can use and make cool!

You could turn the leftover jet skis into motercycles.
