Flush or Run Your Jet Ski - Water Hose Connection

[@Guy-ky9mc]

I have discovered something VERY critical about running these on a water hose. Basically, that water hose connection is used to FLUSH the system..it is NOT intended to run the motor for but just a brief period. Doing so can cause HOT spots in the head around the cylinders and you can destroy an engine. When you run a water hose via that connector, you're basically going backwards with the water flow. Normally (while ski is in water), water flows in through where the jet pump is. I recently rebuilt one of these motors and the number 1 cylinder and piston were destroyed and we believe it was because of running on water hose for too long

[@SeidelRanch]

Really? I knew it was the flush port but they also say to run it when using it. I think the key here is too long. Thanks for the great info.

[@patrickseverson4705]

So is there a wat to hook a hose to the inlet of the envine to cool it with a hose that is the flush hise shown on video the water isnt cooling anything so can i run a hose to the engine via the inlet where the turbin is

[@Uri_ontop]

Thx bro this helped so much

[@SeidelRanch]

Glad it helped

[@wellaintthata5047]

Yeah, like they said. So nice.

[@SeidelRanch]

Thanks.

[@TG0DS]

When I run the Ski should water be coming out of the Bypass outlet? And if not should I flush it?

[@SeidelRanch]

When you are running it in a body of water you should have water coming out of the side bypass. If not you can try to flush it but also check the pump. That is there to let you know it's working.

Thank you, you helped me out.

[@SeidelRanch]

Glad I could help. Thanks for watching.

[@wyattjohnson804]

Great video!

[@SeidelRanch]

Glad you enjoyed it. Thank you for watching. Take Care.

[@bubbaa5220]

Random question, I own the exact same model, but can’t seem to find an adapter to connect my garden hose securely. Would it be bad to just set a basic funnel in the flush intake and turn the hose on? Thanks!

[@SeidelRanch]

You will need something that can take the pressure from the garden hose. The water needs to be pushed into the adapter. I would get a cheap hose and cut it to fit over the opening.

[@jennyb8964]

I just bought a 97' 750 and the owner had never heard of flushing. What type of damage am I going to come across, if any? Thank you for your video!

[@SeidelRanch]

A lot of it is based on where it has been. If it's been in salt water at all, flushing is very important. The salt water can eat away and corrode the cooling system. If you are in an area that gets very cold, there could be stress from the water freezing if not drained. If it's been only in fresh water and kept out of the cold, it could be just fine.

[@IzzySk10]

What happens is your engine will lock up because water gets into the cylinders and it can’t compress the water so it locks up. Cranking on it can cause further damage. You have to pull spark plugs and crank it and hope it’ll fire after you put them back in

[@SeidelRanch]

Are you saying you will water lock the engine if you flush it?

[@rickybailey7123]

It's got to be running before u start the water

[@eugeneprashaw5210]

What is the black knob for that is udder the place where you hook the garden hose to. Thanks for your help

[@SeidelRanch]

Found this online because I have never touched that. "Looks like the crankcase drain plug! Most people remove them and get a crankcase block-off installed. Its real easy. If the plug goes bad it can suck water into the crankcase! They stopped installing them on the SXR." Hope that helps.

[@dylanrozeboom7018]

If you were going to winterize, would you pump antifreeze through this same inlet?

[@SeidelRanch]

All I do to winterize mine is run the water out of it. But, if you are in a very cold climate then yes, you can run an antifreeze mixture through the water port to help keep any residual water from freezing in it.

[@Hey-vk7em]

I live in northern ks and I flush it like this fella. Then run rv antifreeze down a funnel connected to garden hose while the ski is running until the antifreeze comes out the exhaust.

[@danielcobb9456]

The black button thats below the water inlet . What is it for .

[@SeidelRanch]

That is a pull knob to drain the engine of water if they jet ski gets submerged and water gets in the engine. Here is a link to the owners manual if you want to know more: www.kawasaki-onlinetechinfo.net/dispeBook?file=99920-1799-02&mark=JH750C3&manual_kind=OM&model_year=1997&lang_code=EN

[@danielcobb9456]

Thank you . I have a 750 zxi .Couldn't figure out what that black button did . Good to know .

[@mccullough8789]

Cool thanks 👍

[@SeidelRanch]

No problem 👍

[@djflakoelmonstruo9908]

im getting a kawasaki ts 650 wed ill see if it has one tha will be nice to have

[@SeidelRanch]

Hope it does. Good luck on the new ski.

[@timothymcmahon1507]

Just bought a ts 650 about a week ago and mine has a factory one. Let me know how yours goes.

[@baitcastersbroadheads2594]

So if you fill it up with water can it not flood the engine with the water since it’s the exhaust manifold

[@baitcastersbroadheads2594]

Nevermind I should have waited to listen to you say that

[@SeidelRanch]

No problem. Hope it helped.

[@robertbigley5694]

I have a question if I have that hose inside my engine should thay be caps off will water flow out of it into my engine conparment

[@SeidelRanch]

@@robertbigley5694 Are you saying you have a hose connected all the time? That port needs to be closed off or it will fill the jet ski body with water when using it.

[@robertbigley5694]

@@SeidelRanch yes the hose to run thr jet ski out of water ..so it does have to be close of ..ok thanks so much

[@eliwallizer4888]

Thank you!

[@SeidelRanch]

You're welcome!

[@dirtytrucker08]

Thank you

[@SeidelRanch]

You're welcome. Hope it helped.

[@wtfman1217]

Can u run a JetSki with the water hose for 10minutes or is that to long?

[@SeidelRanch]

I have run them for probably 30 minutes or more with no issue. Since the water is just for cooling, time should not be much of an issue.

[@wtfman1217]

SeidelRanch Thankyou for the quick reply I’m so bored in this lockdown as I’m from Australia and want to start her up and just do something lol!

[@michaelcudby787]

The problem with running the engine for long periods, ie, longer than 5 minutes ,is there is no water g0ing through the wear ring, which will ruin it in a short period.When using the ski on water, there is water going through the wear ring, which cools it & stops it wearing out, prematurely.Ever tried to renew a wear ring?Not a job for the faint hearted!@@wtfman1217

[@SeidelRanch]

Thanks for trying but I will mess it up every time. This Texas drawl just eats up all kinds of words.

Iv never heard of no kaawwaskii lol!

You can't expect an old redneck to speak Japanese correctly now can ya.

[@johnerickson2673]

Should B called "Hillbilly Jet Ski"

[@SeidelRanch]

Whatever works. Thanks for watching.

[@patrickseverson4705]

I cant get a straight answer on any question so its best not to run it in your driveway put it in the water

[@SeidelRanch]

Well, it's always best to run them in the water vs your driveway, but sometimes we have to do what we have to do.

[@richardlabonte5813]

Can’t even get the model number right on this JetSki and your video is way too long.. just get to the point buddy seriously I don’t think you know a whole lot about jet skis so you might want to shorten your video in a good mood until I watched this video😂 I’m just annoyed. Edit & shorten this video. Get rid of 75% of the worthless info nobody cares about. Over 6 minutes,when it should have been direct to the point in a min or less..
