[@joshuadaugherty7979]

I’ve known Jim’s Jet Ski for over 30 years. It’s awesome that he is sharing his knowledge for free!

[@spacenut708]

over being the key word...LOL

[@barbaradaugherty5826]

Interesting Jim!

[@juanito2903]

Another great video.

[@jetskijim007]

Thank you for watching.

[@jamesdaugherty-e8c]

well son, you improve on every video. keep trucking.

[@richiefinnell951]

I appreciate you making these videos Jim! Not many videos out there with good info on old skis. I just bought my first ski and it’s the same 650sx

[@jetskijim007]

Glad you liked it. Thanks for watching.

[@havasubooo8840]

awesome editing...

[@jerryhopkins5715]

Trash can-1 Jimmy-0. Great video

[@jetskijim007]

LOL, thank you. :-)

[@AtimatikArmy]

I love that you include little bits of history here and there. I thought I knew everything there was to know on this subject, but nope I learned something new today! Pretty interesting and cool. I''m Stoked there is a channel all about keeping these awesome vintage boats alive!

[@jetskijim007]

so glad to hear! Thanks for watching. :-)

[@lchebuhar9212]

Cool project! 💪👍🏼

[@jetskijim007]

Thanks! 👍

[@Atomotechnologies]

Cool project, i own a couple of 650s with block off plates, I would like to see the reserve tank mod. Nice work Jim

[@jetskijim007]

Thank you!

[@photonman48]

Your explanation of the cooling system at 19:28 was the best I've seen, cant wait for the next video!

[@jetskijim007]

Awesome! Thank you for the feedback. :-)

[@photonman48]

My cooling water stopped flowing in my 650 so this helped enormously 👍@@jetskijim007

[@rickerra]

Excited to watch this project! Thanks for explaining the exhaust mod. Slightly different from the "dry-pipe" exhaust mod (w/ smaller injection orifice and stinger port added). Cheers!

[@jetskijim007]

Thanks for watching!

[@kyleanderson9762]

Most educational exhaust video I’ve found

[@doublem6027]

Too short of a video. Very interesting!

[@spacenut708]

It's only part 1.

[@gittingjiggingwidit]

@@spacenut708 Thx I didn't catch that

[@dougfeehan8421]

Wow -Never seen so many tool boxes -Great video again .

[@danieladdyman9015]

Really great to see and hear Jimmy's experience led knowledge. Such a valuable resource! Big love to you Jimmy for gifting this knowledge to the rest of us.

[@jk-mg8zi]

This guy knows his business

[@chasezurbrick116]

Amazing video. Helped so much with 87 650 build.

[@thomasinnis2370]

Great videos! As someone new to the sport (3 years) but already addicted thank you for all the detail. I've got 2 X2s. A 750SP and a stock 650. The 650 is out now for a carrier bearing and other upgrades.

[@jetskijim007]

That's so awesome! I will do a deep dive on the X2 at some point. :-)

[@raceylacey1124]

Hey JSJ, Thanks for the videos, I learned to ride a 550 while stationed at MCAS Cherry Point NC in 83 or so. The base actually had them to sign out cheap. I recently picked up an older 650 to get back to my boots....or roots. I have the ski ready for a pump stuffer and will get out to Havasu soon for a visit.

[@jetskijim007]

Right on!!! That is great to hear!

[@RyanMcIntyre]

Haha I sold that ski not long before this video was made. I got it from my cousin and as far as I remember, it never ran in his hands, and none of the parts that were with it actually belonged to this ski. He cobbled together enough of the 650 stuff he didn’t want to keep and handed it off to me as a project. I’m not a 650 guy and all the missing bodywork and complete lack of any fasteners turned me off so I sold it. I’m not sure if you got everything, there was two engines, two pumps, like five carbs, a few ignitions including a total loss, and piles of parts. I’m in Peoria and I just found your channel. Looking forward to seeing what you do with this thing.

[@jetskijim007]

Lol, that's awesome! Yeah, it turned out to be the perfect ski for the channel! Welcome to the channel! :-)

[@briangallik9291]

Have you ever dried out a Kawasaki750/800 exhaust? Or have a video that you made that I can’t find. Love watching very informative

[@gocart09]

I'm a new subscriber and I would love if you did something like this with the old waverunner 500 650 platform

[@jetskijim007]

I have been trying to find a superjet or wavejammer for over a year now, they are difficult to come by out here in the desert. People are still actively riding them.

[@gocart09]

@@jetskijim007 lol there's one for sale close to me in Ontario Canada

[@gittingjiggingwidit]

Does that hull have side exhaust? 🤢🤢🤢

[@spacenut708]

same

[@Inflamez1371]

hey Jet ski Jim!, i recently bought a 750 SM X2 and installed a pump stuffer after watching your other videos, What would be a few other essential upgrades thatll get the most out of my 750?

[@jetskijim007]

Just like the 650, modify the waterbox, and dry the pipe out, and for sure modify the hood to let more air in. The stock x2 hood is aweful when it comes to airflow...

[@pauliebots]

What's the " grenade " for?

[@jetskijim007]

It was used early on when the industry was young, and inexperienced users were sinking their ski's often. You pull the pin and it drains all the water out of the engine (after sinking)

[@batteryman16]

What does the bead of silicone do on the front of the ride plate? Just create a smoother transition for the water running over it?

[@jetskijim007]

no, If air trapped in the rear pump area (above the ride plate) makes its way to the pump/impeller area it creates cavitation (it feels like a slipping clutch in a car, or a transmission going out) and it makes the ski run poorly. The silicone is to keep that from happening. Nice catch. :-) Thank you for watching.

[@batteryman16]

@@jetskijim007 I will give that a try, just finishing up a mag pump swap on my WB1. Thanks Jim!

[@willfeather6383]

In your opinion, performance wise, how does this version of bypassing water from the exhaust, compare to the "Dry Pipe" mod?

[@jetskijim007]

I used to do the dry pipe mod. I changed to this because it is simpler, doesn't plug up and burn up the exhaust, and it yields better top end.

[@danscomp66]

When doing the exhaust and T in the water line and welding up the tip do we need to drill the water box out for it too work Correctly? or can I get by for the rest of the summer

[@jetskijim007]

You will be fine. Drying out the exhaust is one piece of the puzzle. Drilling out the waterbox, or freeing up the flow, is another. It all helps make more power.

[@AngelNumberZero]

Hey my 92 TS 650 turns over but gets no spark. Do you know the cause of this so I can fix it?

[@spacenut708]

No whistling? I need whistling...

[@journey_w_John]

I was wondering what factors lead to you using a 15 pitch prop. Is it based on engine power or weight of the rider? I’m thinking about taking mine apart this winter because I live up north. I ordered a pump stuffer and intake grate for it. I don’t know what pitch I have now but I want to check when I get it apart and would like to know if it’s good or if it’s worth replacing before reassembling… thanks

[@jetskijim007]

Engine horsepower is the only thing that matters. If the engine does not have enough power to spin the impeller at rpm, it will be ineffecient/slow. If a rider is heavier, it doesnt affect the impellers ability to move water through the pump, it just creates more drag on the ski itself moving forward. 98 percent of skis i come accross have too tall an impeller in them. A 15 impeller or 8/16 are fantastic impellers for probably 80% of 650's out there.

[@journey_w_John]

@@jetskijim007 thanks Jim. I’m new to skis I just got a 650 that’s been sitting for 20 years and I’m new to them. It’s in excellent shape but I want to go through it like you did with this one and just make it as reliable as possible. I ordered the pump stuffer with the slit but I might take the whole thing apart and check it out this winter. I’m going to try to find that gauge you had for checking pitch and see what I have in it.

[@agraham18]

I have a 1992 kawasaki ts 650 jetski with no engine or ebox just the hull and a few things. What could I replace it with?

[@jetskijim007]

A kawasaki 750 engine out of a 750ss or XI will bolt right in, exhaust carbs electric and all. :-)

[@Xprototype12x]

Why is the “grenade” even there? Like what’s the purpose why can’t you pulll it out

[@batteryman16]

Thanks agin Jim. Im coming back to this as its all helpful while working on my dads x2. Interesting info you shared about modernizing the exhaust. His came with the exhaust modified like Nick does here. Is there a benefit to doing it one way or the other? kzbin.info/www/bejne/mYfHXmehlrmAh5Ifeature=shared

[@DirtyDan720]

LOL my 650 does 52 mph.

[@DirtyDan720]

But it’s a 750 swap with a 10/16 hooker, milled head and Coffman sizzler. But 650 hulls can slide for days.

[@jetskijim007]

The 650 is sooo much more fun once you get over 50mph!! :-)
