Great Job Pete, I am looking forward to seeing the rest of the rebuild. Thank you for the video.

[@PetesGarage]

I'm getting there

[@perltech]

Great job Pete. Your analysis and diagnosis is a lot like what I go thru. It sux that it was the oil cooler - completely external to the engine. Tough but at least what you found makes total sense. This is one for the books!

[@PetesGarage]

Yeah....it's a tad more complex than a motorcycle, but interesting nonetheless.

[@jlm46able]

Hi Pete, thanks for these videos, i just picked up a VX110 and these videos were very helpful to understand the engine components. Hope you got your ski back on the water.

[@PetesGarage]

I'm working on it, thanks JM

[@GDFred88]

I got mine rebuilt and running. I ran it on the drive for about 10sec without water just to see if it would start. Then I attached the garden hose and let her run for about 20 minutes with water flow and variable low RPMs (1000-3000rpm). Then I let her cool down for 20-30 minutes and then fired her back up with water and took her through some higher RPM run-ups and downs. Took it to full red-line a few times. She ran great. That afternoon I took her to the lake and ran her out for a good hour or so. She ran great the entire time. Thanks for all the teardown tips. When you make the rebuild video, it will help a lot of people like me even more. NOTE: A couple of "heads up" notes after rebuild. Put the sensors on the engine before you install the engine. The heatswitch that mounts on the side of the engine block under the exhaust manifold is IMPOSSIBLE to put on once the exhaust manifold is in place. I missed that one and it's not fun taking the exhaust manifold off again once the engine is in the watercraft. Do not not install that sensor before you mount the exhaust manifold!!! Good luck!

[@PetesGarage]

Great tip, thanks Greg

[@coreyhubert1728]

I really appreciate this video series. I've got my last bit of parts coming in today and ill be able to put my engine back together. Thanks!

[@PetesGarage]

Good luck

[@tingovida107]

you should never turn on the water befor starting the engine. water can get in the engine trough the exhaust if the engine is not running....

[@PetesGarage]

+tingovida107 Now ya tell me....lol

[@atlas3863]

yeah I found out the hard way on my 2013 VX cruiser. I left the water on for about 30 seconds after shutting the engine off and whatever cylinder had a exhaust valve open filled up with water instantly. of course that prompted me to actually read the book. come to find out “do not run water to engine Unless the engine running first” then shut the water off first Then make sure you blip the throttle to clear any excess water out of the system before turning off Engine 🤪 luckily I caught my mistake immediately and didn’t let it sit to rust.👍

[@GDFred88]

Yup. I just realized your turn on process. The pressure is too high from the tap if the engine is not running.... If there had been a longer leak you would have found water in the oil reservoir too. But these are great videos. Mine dropped a spark plug core into one cylinder so I need to break it down and see what's up. Thanks for the walk through for that.

[@flylivin]

A typical "I know nothing what I'm doing" youtube video.. Then he has all these lost sheep that follow his chanel and ask his advice for diagnostics of their PWC problems and guidence for their carriers?... Yikes!.. He can't figure out his own problems but he can gude you to yours?.. There are SO MANY TESTS that you can do to determine the cause of this issue without taking the engine apart that this guy didn't do and just blindly ripped the engine out and apart, cluelessly guessing all the way... And he has, and runs a buisness?..... Yikes again! Real repair shops make a lot of money from these "I no nothing what I'm doing" shade tree mechanics...

[@PRIVATEpastry]

@@PetesGarage Love these videos. So we don't have an answer about the status of your cylinder head yet? Looking forward to it!

[@closeenoughmechanics]

I think we all know how your water go in there from your flushing procedure. It’s very important on these to not only turn the water on AFTER starting the engine, but to turn the water off (and remove the hose) from the flush port and give her a couple revs to force the water out of the system. I even do this after I pull the skis out of the water. I’ll give them one more crank and a rev just to ensure that. The oil being in the exhaust is very likely from having too much oil in the tank. Many people freak out when they take the “dipstick” out and see nothing on it. THIS IS COMPLETELY NORMAL for a VX110 that has been sitting up for a while. As scary as it sounds, you have to crank it (start engine, water on, bring up to temp for 3-5 minutes or so at idle, water off, couple quick revs to push water out). After all that, THEN you check your oil level. Ive seen checking the oil level on these dry sump systems mess with even the best mechanics out there just from lack of knowledge of the system.

[@PetesGarage]

What a great comment, thank you

William Neigum Thank you my friend

[@jbower4949]

I would be looking at the exhaust manifold and riser for cracks or gasket leak. Another easy way for water to get into cylinders if it froze

[@WizzRacing]

Cut the oil filter open. See if it has metal that was captured. If it has a high volume of metal in it. Your problem is in the lower unit. Also check the crank seals front and rear. As oil can enter the system mixed with water from the cooling system. You can also order the gasket adhesive from Yamaha. As it is application specific.

[@PetesGarage]

Claude Rains Those are my next steps......Thanks for watching and helping me

[@Skyhighjetpacks]

Where did you find the coolant? I have a 4tech seadoo and had coolant in the system leaking through the pto. Funny enough it's a closed loop and I just heard you say as I type you dont have a closed loop system lol. Interesting. Nice video.

[@travisproteau8285]

Did you find water in the crankcase? Or drain any water out when you removed the oil when disassembling the engine?

[@PetesGarage]

No water in the crankcase.....it is puzzling

[@stonefingers111]

Great videos. I have a new to me vx110 that has 50psi in #2 and over 150 in the others. I have the valve cover off and found all the valves are free. With all the valves on 2 closed and I apply compressed air into the spark plug hole I can hear air escaping out the coolant fitting on the head. I'm assuming a blown head gasket and will remove the head soon to find out. could be a crack too, but I'm hopeful it's the gasket. Motor is out of the ski and I assume the oil res has to come off to remove the head. Also have water in the oil, but could have been like that when I got it. Keep up the great work.

[@PetesGarage]

Good luck

[@poogan1239]

Pete, was this watercraft towed (over 5PMH) dead in the water? Generally the jet pump is used to feed the water into engine via the exhaust system and head inlets you showed in the earlier videos. If the ski is towed dead in the water fast enough, water still flows through the pump, into the feed lines, and backfills the exhaust via the exhaust cooling ports and into the cylinders? Also, the same goes for when the ski is started on a trailer using a flushing system. If the ski sits not running with the hose hooked up and running, it filld the exhaust system with water and can get into cylinders via open valves, hence only a few cylinders show washing. For instance, if they hooked up the hose, turned the hose on, and sat there trying to prep the ski for starting, or it didnt start right away and they left the hose running, this could happen potentially?

[@PetesGarage]

+Paczowski123 It was not towed, nut the hose was turned on first. That is what happend I think

[@poogan1239]

Could be, especially if the hose was left on for an extended period of time. Again, I do not know the exact water routing of that engine, or how the exhaust is cooled, but it could be that if no other problems were found.

[@perverso12345]

muy bueno .keep up the good work

[@chrisdevone7396]

Water can get into the cylinders if you were to flush the engine with the hose before the engine is on. If you turn on the water before you start your engine, the water from the hose can fill the exhaust and back its way up into the to where the valves are and leak into the engine since there are 2 valves open at all times. I had a problem with water in the engine on my fx 160. live and learn

[@PetesGarage]

+Chris Devone I'm beginning to think more and more that may have been the root cause

[@MrMotor11]

@@PetesGarage That was definitely the cause. Always always always start the engine first then water on. Lucky not more damage but you stopped everything quickly enough

Man there are a lot of hidden bolts holding the oil tank on.... I thought I would never find them all even with the service manual in hand. Then there are those six bolts on the bottom edge of the exhaust manifold. I thought I would never see those. I don't have a hoist. So getting in those tight clearance areas with a wrench has been a challenge to my knuckles! LOL! But I would have never been brave enough to start this project without your videos. Thanks.

turning on water before starting engine explains water and hydrolock. Did you fog the cylinders when you winterized it? Fogging the engine could explain the oil.

[@bigblock1968impala]

depending on how much water was in the exhaust already, if the water is running without the engine running water builds up in the exhaust and gets into the cylinders through open valves, and with the cam overlap can actually draw water in faster. 15 seconds is a fairly long time. also that model has been known to stick rings and getting some blowby. if you need a hand with anything related to jetski engines let me know, i do lots of these engines, I'm actually pulling one out early this week, low comp

[@PetesGarage]

ryejetski Thank you....it's pretty straight forward so far.

[@Bobby-oy4fj]

ryejetski I have a similar engine specifically the one from an sx230HO. I can’t trust my dealership and there really aren’t many places in Vegas who can help me. I just did a compression test which found that all cylinders but the 3rd are running normal. I saw that the 3rd cylinder was running at over 300psi an when cranked without a spark plug in it sprayed a brownish liquid which seems to be water mixed with oil. What lead me to this point was oil in the intake manifold plus the oil dip stick kept showing that the oil levels were much higher then the full mark after running but before the oil level was just barely visible on the stick. Have you ever ran into an issue like this or have suggestions.

[@gureno19]

100% you ran the hose on the ski with the engine off, water filled the exhaust and travelled into exhaust and entered the cylinder head. this is why they tell you to not run water through the cooling system in a jetski when the engine is off. expensive lesson, but great video!

[@PetesGarage]

Expensive lesson indeed

[@aspyromilios]

Hi, have you considered that it could be an oil cooler failure (as well as what you already mentioned)? I would think that maybe the oil mixes with the water and and causes problems when circulated. then again you said the oil didnt look hydrated so my theory may be totally wrong..

[@PetesGarage]

+aspyromilios I think you are right. I have found no major problems with any part so it must be in the oil cooler.

I’m looking for the fourth installment of this series to see where you found the problem. Did you ever find it? I’m having the same issue and the head gasket does not look bad but not perfect either. I’m wondering did someone run the engine and then cut it off while the hose was still running. The head is flat and the block surface is flat as well. Where else could it be coming from?

I did not make it yet, I did not find anything wrong. it was from running the hose with the engine off

[@mitchhayes1969]

@@emoreno101 It has been a low priority project, and I didn’t want to put a lot into it since it was given to me by a friend who didn’t know how to go about fixing it. The jet engine has not run in 10 years BUT despite having water in it, the engine still turned over. The crankshaft appears to be stainless steel and was perfect. The pistons were a different story. The rings has welded themselves to the pistons and could not be reused. The bores were pitted enough that I had to spring for a set of WSM pistons at .25mm oversized. I took them to the machine shop and had to pay $190 for a bore and hone job plus checking the block for cracks. Just got it back and need to reassemble.

I'm having a similar problem. When I started my Waverunner last weekend, it was hydro-locked. I removed the coils & plugs and cycled the engine to clear the cylinders. Clean the plugs reinstalled everything and it started fine, but, without being connected to water. After putting the Waverunner in the lake, it started & ran fine, but, then quickly shut down. I noticed the plugs were fouled and there was water in the oil reservoir. Therefore, I drained the oil/water and cleaned the plugs. Once again it started, but, then quickly shut down. Noticed again there was water in the oil. Took the Waverunner to a shop. Btw, my Waverunner is stored outside in northern Michigan. Thinking I may need to store it in an enclosure with some heat...

So I am getting water in the oil on my 2015 VX. I have flushed it 3 times. I forgot to put the plugs in one weekend and the hull filled with water. Long story short the engine hydro locked and stopped. I am guessing it could be the head gasket? What are your thoughts? The engine runs fine but the oil gets milky. Wouldnt a compression test help give me an idea if its the head gasket?

[@PetesGarage]

Yes, do a leak down check to see if is the had gasket

[@cee169]

Petes Garage I did the leak down check and all four cylinders went to 90 psi and didnt bleed down. Thats a good sign I suppose. I thought 90 psi is low for an 11.4-1 compression ratio. And there was no water on the plugs. Im wondering if I just need to flush more oil through? Maybe three times is not enough. Any ideas what else I should do?

[@PetesGarage]

Drain all of the oil out and start from scratch.

Start the engine and then turn on the water if your running it on a garden hose. Or water will enter the cylinders everytime it back flows through the exhaust. And the cause of oil in the intake ports is from over filling the oil sump always run the engine for 10 to 15 minutes before checking the oil level they will always show low oil on the dip stick when the engine is cold.

any concrete verdict Pete? I have one of these sitting out front with 30psi in each cylinder :/ going to tear mine down soon thanks to your videos

[@PetesGarage]

Looks lie the oil cooler was cracked

[@randyhernandez6519]

@@PetesGarage i have the same issue, milkey oil.....No warning lights and no loss of performance...so far 4 oil changes no luck. I was hoping mine is the oil cooler and not a head gasket (out of my league repair). any pointers and can i pressure test just removing inlet and outlet hoses from the cooler installed? "with under 15 psi?

[@ziggassedup]

Crikey Pete...That's a curly one...The lack of contamination between the oil and water is strange...None of the cylinders have moved have they.?..That would account for the water but not the oil in the manifolds....I'm keen to see what you find.

[@PetesGarage]

This is the root cause problem to solve: Took the craft out of the water and ran it to clear water. It ran fine. It sat over winter, covered. This happened at first start up. What could possibly happen to cause the failure? I'm assuming something froze, but is that wrong? How can you put something that works away, then take it out to use it and it is broken. It does not make any sense.

[@WizzRacing]

***** It happens more then people think. We used to get 20-30 every year with blown seals, cracked blocks, seized cranks etc.. All because someone didn't properly winterize it or they submarined it and tried to start it. As you have to remove the plugs and crank it over first. That way all water is removed from the cylinders. That the air filter let in or from the carburetors intake. We used fogging oil and a mixer of antifreeze and water to flush the system. Sprayed the outside or the engine with storage oil. Removed the battery and filled the tank with fuel stabilizer. I never had one fail when it come time to prepare it for use. It's all in the details. I think you also have two problems now. Not just one. Look close inside the intake and exhaust. pipes. Maybe even block off the ends. Then pressure test each runner. See if you find any water or air leaking through the walls.

[@alsosteikje]

Also check oil cooler. Probably frost damage here, causing the oil to force its way into the cooling line over to the exhaust manifold. Pair this with a damaged head gasket, and i think youre on it... :-)

[@PetesGarage]

alsosteikje I think you're right...

when is the next video coming up ? :) i love them so much !

Absolutely

Pete so what was the problem with the jetski waverunner engine I have been waiting for the answer. Or the next video thanks for the great videos.

[@PetesGarage]

I'm thinking water went back through the exhaust into the engine. I did not find any cracks or other problems.

[@universal1star]

Yes, most definitely the issue. Has happened to numerous people. ENGINE RUNNING, THEN WATER ON.

[@JosePerez-bz4ix]

Hey Pete have you find anything about the engine?

[@PetesGarage]

+Jose Perez I have not found anything significant. I think it's in the oil reservoir and

[@purplexenno]

+Petes Garage if i may, check the diagram with the oil chart, notice the part on the side, where the water goes by the oil container jacket. It could be that the inside has a very small hole and you have a vacuum building up and pulling oil with the water. (i would point out that, at this point i'm just guessing based on what i see. Unfortunately, i'm not there to look at how things are set up) If i was to place a bet, the metal is from either a pump or something of that nature where it's broken and it's causing oil to be "pulled" up with the water. LIke i said though, i can't really tell since i'm not their to look at it. Hope you find the cause though. Good luck.

[@SWFLJetSkiRiders]

WHERE'S PART 4, I wanna see if the marks u did to line up worked . Thanks

[@PetesGarage]

I didn't make part 4 yet, I simply haven't had time

[@waynefortier5978]

Water got into your cylinders by turning the water hose on before starting the engine, once the engine was started in Hydraulic it’s pushed oil through the valve guides

[@PetesGarage]

Absolutely

[@jimnoneother6317]

Awesome

[@PetesGarage]

Jim Noneother I'm getting there....thanks Jim

[@dawsonmarineservicesllc2163]

Pete, yes it was from running the water with the engine off. Many make that mistake. I hold the dealers responsible for not giving a post delivery training on how to take care of your new ski. The water filled the exhaust then back flowed through the exhaust valve. That's how the water was in the cylinders. That being said please continue with the rebuild on the engine. Covering assembly and valve adjustment IAW the manual steps please.

[@PetesGarage]

Thank you very much

[@simonnorup]

check if the block and/or cylinderhead is distorted it could be the shelve that has fallen down in the block

[@PetesGarage]

Great idea!

[@miketerry6784]

Wheres part 4? Was the issue found

[@PetesGarage]

I did not make it yet...there was no issue found.

[@danparedes8706]

I can't find part 4. What was the culprit?

[@PetesGarage]

There was nothing wrong, coolant flowed backwards into the engine

[@danparedes8706]

@@PetesGarage I took the filter box out of my skis and did cool air intake and catch can for breather tube. No more oil in the intake 👍

Nick Webster I was just about to ask the same! Pete, thank you for these videos, I am tearing mine apart for the same reason. A time consuming error on my part by having water running without ski on. 😔 Good news is, I was upgrading valves and cams anyway!!

[@inspirationjam]

so where is the video on the conclusion?

[@PetesGarage]

It's been awhile, but I'm getting back to it.

[@rs72143]

I'm no mechanic (as my bike will attest to) but I was thinking the oil res was the source of the problem.

[@PetesGarage]

+rs72143 I think you're right.....more to come

[@dustina7402]

You hydro locked it when you turned the water on first before turning the engine over. Stern drives require water before start but the opposite is true for jet boats such as a wave runner. You must start the engine then turn on water.

[@PetesGarage]

You're right

[@dj1dj2dj3xxx]

Hai Pete, The water you noticed was during the engine was still in the hull of the jetski or also during testing the engine outside the watercraft? With a proper test of the engine by starting the engine and after a few seconds open the waterline and let it run for a while, then close the waterline and let it run for a few seconds and then turn of the engine. There should not be any water in the oil or where the compression takes place. If there is there is Obvious something wrong.A known failure of this watercraft is the sealing of the drive shaft, after running the engine and keep the watercraft into the water it will leak a lot of water (by pressure of the water outside) into the hull, If there is no seperate bilge pump to hose the water out of the watercraft and you will start the engine after a while, the water will be sucked by the air intake into the engine and will cause serious problems.It can be one of the possible reasons why this occure otherwise you have to investigate the engine on other failures.Thanks for your you tube topics, they are awesome, keep on doing these, you help a lot of people with them.Best regards,Denny from Amsterdam

[@PetesGarage]

It was an odd problem. I did not find any major problems inside the engine.

[@dj1dj2dj3xxx]

A pitty of all the work you spent on the engine, Four stroke engines and watercrafts are not such a good combination unless you are very carefull with the water entering the watercraft and the damage it can cause to the engine. There are more possible causes like the cooling hose that sucks water from back of the pump to the exhaust and engine which is constructed too low without any loop or high level point. after shut of the engine the cooling water will still push the water through the exhaust upwards inside the engine.Even a bad circulation of fresh air while not running can cause serious problems to the engine if stored for a while when there is any water in the watercraft.I hope it will run good and for a long time without any problems after reassembled everything.Good Luck, Denny.

[@PetesGarage]

Thanks Denny
