thats a gremlin not a shark!

Thanks for the info. Great video

Could you do a video on winterization?

Thank you for doing the video. I've noticed in a lot of the Facebook groups people are using Harbor Freight or other cheap gauges and getting inaccurately low results. Just today somebody had an engine with 90/90 using a Harbor Freight gauge. So using an accurate gauge is very important. If an engine has bad compression very often one cylinder is a lot lower than the other. So you wouldn't want to pull an engine to rebuild the top end based solely off one compression test. A fully charged battery is important too.

twice the size of a 550, its almost a boat!

What I appreciate about John making these videos for us is the fact that he’s not profiting from slowing down his day and filming/editing these videos. He’s actually giving more and more to the community of riders, and future riders by making all of these wonderful videos for us.

Good stuff. Hard to find good in detail PWC repair and maintenance info, keep em coming.

Think I heard Chris Fischetti name drop you in that Ride By Day Wrench By Night podcast from VintageJetSki the other day. Always helpful dude!

Keep making videos we love them, more builds and how tos and what not they are all good! Keep rocking!

The man, the myth, the legend.

Nice video!!! I always do mine with the throttle open but both plugs out. So when you do it and leave the plug/s in do you leave the wires on the plugs that are in the head or ground them put somewhere else? My skis will run on one cylinder 😂

What does it mean if my carb wont hold any pressure on the pop off test? It just constantly drops pressure

Thanks, I seen "pop off " mentioned on a FB group and was totally lost. Now that is out of the way, will visit your site as I will need parts here shortly. I have a Franken Jon and most likely will have to modify the carb to get more bottom end. 61 x is what I am installing as my 62 g and other 61 bit the bullets.

Can't find any place like this in the northeast.

Im pretty sure this just happened to my x2 also the motor wouldnt rev past 50% throttle and batteries not charging so im assuming the stator is dead.

I never heard of squish but on 4 strokes its called quench

Off topic… did you end up getting any numbers on that 2023 EX? You had mentioned a possible 5 mph gain. Did you end up getting a wrap on it as well? I have a 2020 and I don’t like the black top deck. Just wondering how a wrap will actually hold up over time..

🇦🇺🙂

Had never heard of that before this video

Best video of all loved it 👍🏾💯🙏

Hi new the the channel but really like the video u make for ppl and educating us about all the different type of jet ski, I would like to see of a video of a fully built 1988 js550

So on 2012 they're are 3 holes for steering angle but yamaha says only 2 can be used. Why can't the outer most one be used? Is it due to cable bottom out? And this may be wrong video but looking at trimming it. It looks like it has a bolted trim tab. Can you manually trim the ski with that?

I sure miss the Xtreme t- shirts . Youve got a classic hanging on the wall by the wetsuit .

Beeeuty build

love the content as always.

Odd question, could you tell me what the pitch of the stock impeller is?

Wow, can't believe I never thought of this! Excellent tip!!

Thanks John, I never saw that before

Is squish always .045 on all 2 strokes? I agree with lucievedl. You need to do another video and explain why you would do a squish test and the pit falls of too much or too little squish...and how to correct squish if it is out of spec...and what would cause incorrect squish in the first place? It is very important to know the proper way to do a test, but it is more important to know why you are doing the test in the first place. I am not trying to be overly critical, I just think this video left more open questions than it answered. Should I check all my old 2 strokes even if there are no performance mods on them?

Hi John , great video on how to measure squish ............ what's missing is WHY measuring squish ...............WHY is quish important to check ..................WHAT is squish do to your engine ...................WHAT can go wrong if you don't have the right squish ..................... in a few words getting more education on that word "SQUISH" ............ Best regards from Belgium.............JACK

Thanks

Sorry it is hard to see as I get "off Camera" but when measuring please make sure you measure ONLY the very end of the soldier. Remember the squish band is tapered, and is at its thinnest out at the very edge. This is where you NEED to measure. You really should turn the calipers 90 degrees to the soldier.

Great timely video, a friend asked me how to check squish and I explained it to him, but this video is an excellent visual demonstration.

It looks great . Did you put new graphics on the ski ? What brand of tray / deck padding kit did you use ? Waay back in the day we bought this ski brand new for my wife. Wish we still had it but I do still have my 1986 550 all of these years later . Thx for anither video .

Where are these skis??

So it would appear that you could run a 62t gasket with a 61x head b/c its so much more open. Just not the other way around.

Buying one with 11 hours only freswater but owners wont let me test drive before buying due to our salt waters anything i need to know before purchasing ty

Can you out the 62T gasket on a 61x?

Hello, thanks for your video. Can you help me choose the best one for my jetskit GTI SE 170 2023 thanks

Hey great video. Learned a lot from it. I have a 61x (in a js550 hull) the water inlet line from pump comes into nipple on bottom of exhaust manifold, up through the water jackets in the exhaust manifold, through the cylinder, into the cylinder head, and then the port on top of the head… is that line supposed to go back to the bottom of the exhaust manifold next to that inlet nipple? Seems like it should be going into the exhaust pipe(maybe that nipple does?) thanks!

i just got a new superjet and i love it so much

Is price still 25k +?

Hi John, Is it a good idea to fill a js550 handle pole with expanding foam? I noticed its empty with a drain hole at the bottom near the pivot. Thanks, Simon

Awesome review

What boats did you use to race John? Im also into high perf boats, have a 100+ mph eagle one with a 15" 2.5L 200ff merc

Heyyy John!! I’m new to your channel. Thank you for all your really good and helpful content!

Soooo what’s the pop off psi asking for a friend 😉 J/k Thank you for the info

always great video , thanks for taking the time , always helpfull info's !! ( Best regards from Belgium ; jack )

Another great video John. So, if one would want to run a different Kawi plate… should they also change out the cable as well, if so… what cable would one want to use?

Thanks for all of this good info . Extremely helpful...
