V8 ski weight

[@vivogarage]

Weight will not be an issue especially if it's under 1000 lbs, This thing will rock! Great job on this build and look forward to seeing it start up and getting out on the maiden voyage

[@user-nu2pp5tc5q]

The first ride of this ski will be one of the best videos of the summer..can't wait 🤪🤪

[@SeaDooEric]

My 2011 SeaDoo GTX iS 260hp weighs 980 lbs dry and is pretty quick even at that weight. Yours will move just fine at 900lbs with a V8

[@taylorpratt6287]

Now imagine if the gearbox holds together and spins the prop fast enough and then he does heads and a cam and makes 500 ish, I think it would be a good idea to do a belt drive instead of the gearbox, quieter, far less heat, not gearbox to possibly grenade and if it does fail, a belt breaking would be pretty mild he comparison and he could even keep one handy with a few tools onboard to change it on the water instead of being dead in the water with possibly hull damage but I’m excited to see how the gearbox works out for him, should sound awesome at least, this is a pretty cool project, I’m impressed at the weight, I’m sure it’ll gain around 150 lbs with a full fuel cell, wiring, electronics, cooling system, and the rest of the misc stuff, still should be a rocket

[@JoelArseneaultYouTube]

Nice ! That's not much extra weight at all ! I was thinking maybe 2-300 lbs more. 100 lbs in that beast is nothing. I'm guessing that it won't even be noticeable considering it is designed to be ridden with a passenger. The engine weight is nice and low, unlike the weight of a passenger. It's coming together. When I saw you cut an angle on the exhaust, I immediately thought "glad I didn't weld then on" then you said it :) Great progress. Well done.

[@jasonsparshott7208]

Hell yea I love it !!! Screw the haters if there dumb enough to think you are going to actually fill that fully custom reduction box with sand then ....

[@bernielomax4859]

That one handed chuck action while holding the mounting bracket in place was next level 🤯

[@Savannahjbo]

have you had previouse experience with the riv nuts on a ski, I was a lil surprised to see you NOT use 3M5200 in the holes before you installed them ..

[@anthonygrasso8620]

Could you discuss the cooling system of the v8? Closed cooling with riser with heat exchanger?

[@tommydunn8608]

I think it will run great and the weight will barely be noticeable! Keep up the good work!

[@MultiLarzzz]

The weight will make a huge difference. It all depends on the vertical center of gravity and if the weight is centered in the lengt. It won’t sink, but it makes a big difference!

[@northernminnesota4685]

These videos are addicting, also hope to see more of the BOB ski build

[@nickbaddorf2673]

Love the build! Can’t wait to see this run!

[@brandonburt4244]

Man I can’t wait to see this on the water

[@stevejohnson8703]

I thought it would be about 200 extra lbs. We'll see when it's done and operational. Great build,I'm ready to see it run. Still think gears are gonna scream. No mufflers should help

[@mikewilliams7993]

An aluminum block LS is 100 pounds lighter than the iron block LS so it would be easy to swap one in if weight is an issue. Nice work I am liking this build, and good luck with the first run.

[@dillee9988]

I can't believe the difference in weight is so small, but you should be fine anyway, a few other guys have built V8 jet ski's, and they are floating fine. I would if I were you put as much buoyancy in the ski as possible in case of a roll over. But I can't waite to see and hear it run. You are doing an awesome job. It's going to be like a Boss Hoss motorcycly, totally rediculously awesome. I'm a V8 fan.

[@jshrawder49]

Looks like it should be fun!!

[@jeffjodyauman7774]

Wow. Impressed good job. I would pickup an aluminum 5.3 block should be easy to get and knock off the added weight back to factory spec.

[@Breakitjake]

I prefer having a passenger on my FZR. makes it more fun when hooning around. Digs into the water better. So I don't think the weight will be a drawback

[@jeantsaiaviation]

It will be good for 2 people i would say.

[@piquat1]

I was one of the ones wondering if it would sink. Nice to see it only added a hundred pounds. Not sure how that worked out but it sounds good!

[@scottsmith2869]

I here’d you mention to put the O2 sensor bung in that lower pipe. Won’t it be wet? You may need the O2 sensor in one of the runners coming out of the dry exhaust like just out from the head? Not sure, but just wanted to mention it. Great build! Thanks for the video

[@FryChicken]

This is my favorite youtube notification. For the life of me I don’t understand why you didn’t go for an aluminum block. I guess cost/availability.

[@DrewCampbellRacing]

Great build! Keep at it🤘

[@michaelfowler8289]

I'm not sure if you have thought about it but if you have seen some of the drag boats they have a water-cooled exhaust that use a bung in the exhaust to run a tube that pushes water into the exhaust to help cool it

[@js64984]

This is going to be awesome!

[@skun80]

The reason for the hull inside is not simetrical from factory is because they calculated the rotation of the engine and propeller and compensate this rotation. If they did not do this the jetsky will run tilt of one side

[@rickems8863]

FANTASTIC RESULTS, I swear it would have been heavier. This thing is going to fly.

[@mp6756]

Love the progress I started following along thinking this would never work out. At this point I think your gonna pull it off. I like the aluminum headers, but I'm not to sure about the temperatures of the exhaust. The o2 sensor getting flushed with the h2o might be a bit of trouble for the ecu to deal with. Good progress

[@donovanwhite2244]

Throw some extra spray foam insulation inside every nook and cranny once it's back together, and I'll approve it! No worries there! Lol

[@chasefreedom5178]

If it porpoises trim will need to be added. Add buoyancy might be needed. Looking forward to the journey.

[@96Dak318]

With enough impeller pitch i could see this thing cruising around 35-40 at 3000rpm, it certainly has the torque for it. Wonder what kind of run time/distance you’ll get out of this thing.

[@techdoctor9982]

love the idea but an engine mount without any vibration damper isn't going to stay in there for very long - the damping isn't just to insulate noise from the hull but more to insulate the vibrations from shaking the fixtures out of place - whether you live long enough riding it for this to happen with a v8 in there is another matter :)

[@seanthompson6720]

it's definately gonna sit lower in the water but a big jet ski like that has no problem with 500+ lbs of riders, think it's all gonna come down to dialing in the right gear ratio in the transmission. it looks like right now it's around 1:2 or 1:3 but you have a ton of torque so you can go bigger 1:4 maybe 1:5 if the box has room for it

[@robh87]

Its gonna handle like running double on it but a bit better as the extra weight comparable too a second rider will be low in the boat, as opposed to dangling in the wind up high. ImO its gonna carve really well and have tons of tourque from idle to WOT if you dare to go there. Am curious the prop you have chosen? Dual grind like i have in my jet boat or what did you come up with?

[@rhyswilliams695]

I was expecting it to weigh more. 100lbs is the weight of a second passenger, which these things are designed to carry, so should be fine. Nice work!

[@kimkeam2094]

How did you go with the balance compared to a factory FZR? With and without fuel with a large tank could create an issue. Love the work!

[@sleepinfocus02]

if it hasnt been asked already..... how are you going to run 02 sensors in a wet exhaust? they would have to be in a jacketed section but that also has to be far enough past the main collection point in order for the ecu to capture an accurate reading on each cylinder pulse. I dont know where that point might be for you.

[@ETCJPACE]

It’s a big two seater that now will be a big one seater. Two on a pwc is no big deal. This boat will do fine.

[@haterlogins1131]

Can't wait!

[@renefontanez1531]

ADD, turbo housing and exhausted 😁😁, you will need it

[@hamzazaatiti2532]

I like the v8 jetsky

[@terryscarlett2431]

Must have took my sinking comment on the weight to heart...lol

[@charlie2king]

Oh man ally block would be the go

[@charlesplewes48]

Why no rubber mounts for the engine? Without any rubber mounts will the engine vibration not eventually make the hull fail?

[@DaveGym2.0]

100lbs, what's that, an extra person? It'll be fine. What LS is that? I think only the LS2 had ally block? We don't have much LS in the UK but I put an LS2 into my Mazda RX7 and it was inane. In a ski is just mental

[@mickotoole4795]

Jacob how many times have you lifted that top off . The V8 build .... 🤣 think I'll go back on all the vids and see 🤣🤣🤣🤣🤣🤣🇨🇮🇺🇸🇨🇮🇺🇸👍🤔🤨🤨

[@averyanderson6945]

It will be fine it’s less then what it would be with a second rider

[@foreverendeavors6210]

You can Ls swap a jet ski and keep it near factory weight, I am interested!

[@jeantsaiaviation]

It wil not sink, i had a 2009 fzr and we went with 3 people on on, but it was a little sluggish and not well balanced. This project will work because you have more weight but also more horses.

[@Yohann67]

I think the extra weight could be offset performance wise by adding a couple turbos. I think 1200 hp should be your goal; nothing exceeds like excess! 😏

[@taylorcarson9213]

Its going to feel great all of the weight is low i figure you will be closer to 1020 pounds when you done but the ski can handle 500 pounds extra safe.

[@ryanjohnson1814]

Curious, gear drive, rpm ratio, what top speed will be.

[@mickotoole4795]

Vin vin ya have to say I'm 🥇🥇🥇🤣🤣🤣🤣

[@vinvinn7050]

Oh well then I'm last disqualified.congrats Mr O Toole🥇🏆🏆🏆

[@chriscoralAloha]

A hundred pound plus passenger goes on the back. Sometimes even 2. The extra weight is low and centered. Only thing i can see is lower RPMs.

[@EnemyDwarf-TTV]

its a great idea and cant wait to see it finished not sure that the LS is going to be so kind the that hull without any engine damping, ie sat on rubber mounts. its going to want to twist like a bitch. nope i dont this its going to sink at all, these are designed to carry 3 people so adding 150lbs is nothing keep on the good work fuck the haters!

[@petteriu]

Weight increase is not that big, but what about weight distribution/balance fore-aft. Even still, it's currently in par with a passenger onboard and like placed equally.

[@tommygunnz7154]

Don't know jack shit about jet boats but just watched Finnigans garage. he's building another ls jet boat. And brought up a important point. About oil pans. Seeing how there is no trans. oil volume is huge. Needs about ten qts. May want to check it out. He also mentioned the name of the company that makes one. Hate to see ya cook that engine on the first day out.

[@latunguley]

Hey it's been over a year? Have your rivnuts held up? I'm thinking of using them for a boarding step on a 2001 XLT 1200

[@JetSkiBrothers]

They are solid, only thing I would say is hand tightening the bolts into the rivnuts is a must. The impact will loosen up the rivnuts

[@iechiefcherokee3807]

That’s what my 1.8 vx ho weight

[@umhewwo8006]

What about an aluminum block? Is that still a possibility

[@kellyvandam4594]

What about the battery? that might add some 50LBS

[@smplyizzy]

Are you seriously looking for an aluminum LS? Have you considered installing any heat wrap on the exhaust and or hull?

[@phildawe7172]

maybe but i'd reckon the large influx of new cold water usually drops the temps down wayyy better than if it was in a car. (exhaust is liquid cooled too)

[@maroz2881]

What about the fuel cell with a full tank

[@Javaster918]

Why don’t you guys get a riva kit for that far engine in the gp1200 Bc that will make it go like 80-90

weight is just like having a fat girlfriend.. no problem!

[@danratsnapnames]

you fogot the weight of the rider, the weight of the gas at 6.3 pounds per gallon, and weight of handle bars, and jet drive, and electronics.. honestly, thinking you need to add about 300-400 pounds to that total weight. so you may be ok, but likely your gonna want that aluminum block for the extra 100 pound free up, and to help with corrosion. but just my internet half cent of thoughts.
