First Test Drive 100HP Micro Jet Boat!

we put a 100 horsepower engine into a six foot micro jet boat and this week we finally get to put it to the test but first we need to finish our custom exhaust system and at the end we'll attempt to navigate a river and a deflating air mattress yeah i'd say we've lost a pound of air it's really bizarre making the exhaust pipe out of rubber hose but that's the way it was in the jet ski and when you have water spread in your exhaust here and your manifold cooled then your exhaust charge isn't that hot also i would imagine this much rubber hose probably acts as a sort of muffler [Music] nice the tube extra snug yeah uh i'm gonna go ahead and not put that all the way in there could be very hard to get it out [Music] [Music] this is uh my overly fancy and complicated mounting system for this little you know exhaust flappy flappy i just made this threaded stepped bung so you know that just gets bolted on there this will be welded onto the hole and i just need to make another one and then that's my flappy flappy mount [Music] extra premium and if i rotate this that way then it won't hit anything let's see right there's probably yeah looks a lot better than the old setup yeah this muffler looks a little funny but hey better than a garbage can looking thing that came on it [Music] yeah well that's something [Music] i've been drinking ag-1 for over a year now because it's just so convenient instead of having all of these pills and powders and supplements just every morning put on one scoop into 8 to 12 ounces of water give it a shake and i got used to the taste really fast you just shake it up really quick drink it down and you're good to go ag-one is nine different health products in one giving you the equivalent of a multivitamin probiotic mineral and more athletic greens is a nutritional drink and it offers immune support which is why i drink it every morning they have a special deal for you where if you sign up for athletic greens using our link in the description you will get five of their travel size packets and then also you will get agd3k2 you just drip a drop on your tongue every morning get everything you need with your vitamin d simplifying your life and you get it for free if you sign up using our link in the description all right so i'm designing up my uh new exhaust mount and i figured i'd do it in cad and you know cut out the middle for weight reduction with a new shape instead of a hexagon we've got an ellipse [Music] yeah that might work put a little bit of the bend in it clean it up well the answer hello hi trenton this is edwin and ethan from grind hard okay awesome you you won the ark droid giveaway no way yeah yeah for real oh that is awesome yeah the ark droid and the plasma cutter we'll uh get it shipped out to you straight away awesome thank you so much another winner [Music] well i guess where's it gonna go there's actually a hole in the exhaust manifold that i'm gonna need to fix [Music] kill the water well it's a lot of water that was the thing i forgot a hose clamp on so it blew off oh i can't wait to go wakeboarding behind this thing oh dude that's going to be so funny we also need to pull you on that pink inner tube again oh yeah but quicker this time can you take my phone i've already destroyed three of them [Music] and it won't be snowy yeah yeah that was awesome it's so real man it runs so good too it's snappy i mean you heard that was just super snappy [Music] first up on my list of things to do before we test drive it is put this in here um which means i have to cut it out around the exhaust and then make like an extension heat shield thing around the exhaust so first up that and a bunch of other little stuff and then take it for a little rip in the pond [Music] getting closer and closer to our first test drive i've got this uh cardboard box enclosure around the exhaust we're about to order up with some sound ending and a nice comfy seat for this thing we can take it for a test drive once we have all that but first i'm gonna turn this cardboard into aluminum [Music] more chunks of ranger gas tank [Music] so [Music] so [Music] [Music] when i cut this hole in here i hadn't really planned out what this was gonna be yet so i cut it super close to the pipes there's no need for that so i'm going to cut out a little bit of extra here just so it's easier to get the exhaust in and out [Music] sometimes welding aluminum is really fun and sometimes it makes you want to die especially upside down in the reverb chamber yeah it was frustrating but it came all right all the welds that you can really see turned out decent [Music] we got a drum set if i had any sense of rhythm we would have a drum set [Music] you look comfortable in there oh yes very comfortable just drilling some holes for the uh to zip through the wiring up [Music] can i hand you this yup it's always tricky it's always uh it's always tricky working the dog has decided that every time we film he has to yell yeah what is your problem if we turn the camera off and talk to each other no problem yeah it's like he knows the difference it's always tricky being underneath the dashboard working on stuff uh it's not my favorite thing to do but even trickier when it's a six foot jet boat with a dashboard that's only two feet wide [Music] [Music] i got that and fitting welded on there so it's all plumbed in i'm just going to weld a little tab on here so i can bolt that in and then we will be bilging [Music] room [Music] but the seat's not going to be here for a few days so we're going to test drive it now because [Music] that's what we do because we're impatient [Music] [Music] it's our first time really using the ranger as a truck [Music] oh it's cold still it's literally faster and idle than the drill was i'll go ahead and grab some tools and pop the carbs off and um see if we can't fiddle around and get it running a little better and i'll take this plate off that'll get better access what a bunch of morons oh i figured out the problem yeah there's shop towels in the intake oh really yeah no way when will took this thing apart and then like put it together for storage he put shop towels and all the like orifices which is like generally speaking a very good practice and it turns out uh there are some sucked into the reed valves so it's sucking air through shop towels well there you go she was not getting enough air your idea was right yeah what amazes me is that it ran decent enough to do that or to like rev out on the exercising table at this like not a little bit oh how is it even running that good at all well i mean air can go through these i mean wow don't breathe in through that you'll pass out oh man this is so exciting now i'm no longer worried about like fiddling and fiddling and fiddling like this will just run just pulled out the whole reed valve assembly here hmm yeah that'll make your engine not run 100 well now that we've got half a pound of shop towels out of the uh intake ports we're ready for a proper test we gotta figure out what kind of plastic they put on the bottoms of these things that's different [Applause] hmm that's a slightly different experience yeah dude you were splashing all the way up here i need to work on the intake to shape it a little bit better the great thing so it really pushes water in there but holy crap that is a different beast but it's actually crazy controllable like even in this tiny little pond you can just be like it's just weird to think that like to turn the hard part is to remember give it throttle to turn like if you're coming up to an edge you don't let off to go around the corner yeah you have to like let off before you get there and then go brap and it'll turn because like otherwise it'll just coast it's so handy having this tight turn radius in the truck i'd say overall that was a great success we got a good little test rip we gotta all have fun with it while it was super slow and lame and then uh rip it around a little bit with you know actual power and now i know some things we need to improve and we can be that much more ready for a proper test drive in a larger body of water it definitely needs some uh leak fixings there's a fair bit of water in here great success and next episode will be more fabrication and hopefully more ripping [Music] so i rarely have the opportunity to show how big of an idiot i am on the youtube channel but today is our day so we had a friend over and she was sleeping in our inner back place lost complete air throughout the duration of the night i was like it's time to retire the air mattress so i thought let's float down a river that we can't take out for like two hours even if it stays afloat and just have fun you know it's a raft for an indefinite amount of time and i just thought it'd be a fun challenge an indeterminate amount of time we are not sure exactly like a pump built into it no that's the bummer it's actually it's a nice air mattress we could fix the hole couldn't we no no these things are impossible i'm already getting bit by like 50 mosquitoes so i know we're gone we're done already the mosquitoes alone are gonna put a hole in our air mattress yup you know what they say what do they say when you got party clothes it keeps the mosquitoes away but stupidity hurts isn't this stupid this is pretty stupid all right we're down here and we just realized we forgot an oar which i was trying to remember [Music] the air mattress is potentially already looking less firm the closer and closer we get to actually committing to this the worse and worse of an idea it seemed oh uh i'll swindle out on the edge i'll paddle us let's go this is probably the fastest part of this entire river uh our only real rapid oh that's our class nice that was pretty fun literally said let's pause because we're headed for armageddon those logs might end to this air mattress mite is a soft soft term there averted [Music] yeah i'd say we've lost a pound of air [Music] oh no now we just gotta walk across this field to the van steven's trying to outrun the mosquitoes edwin has given up on life steven is a mosquito bite look at my eye dude look at the swelling [Music] we're testing the athletic grains packaging here we uh dropped it off the 25-foot tree house and we are seeing if it indeed all stayed in one piece i think we're okay let's go see undisturbed everything's perfect great setup
