Bad Practice to turn the hose on before the ski is running. Always turn the ski on THEN the water or else you risk water backing up into the motor and hydrolocking it. I've made that mistake before. Other than that, great video!
im very confused by this, i thought you couldnt run it atall without water? and how does the water interfere with the engine other than just cooling it??
@ofchilds you can run it without water just not very long I always do a test start before I go anywhere so I know everything is working then shut it off after about 10 to 15 seconds.
Someone just gave me one of these that needs a top end rebuild! I was considering getting a whole motor because it’s been sitting for eight years and the top end is not on it. After seeing this maybe it’s worth just doing a top end?
It all depends on how good the motor was taken care of before the low compression. These skis were in great shape so I decided to risk it. Also since they were free, you have almost nothing to lose if you throw a new top end on it
Just a heads up, I searched and troubleshooted to find out why my pistons where scared up and why this is happening. Come to find out it's very common for the oil pump shaft to fail causing motor damage, my shaft was completely ruined causing no oil to be pumped into the cylinders.
@LIFEBUILDZchannel yes! Look up seadoo oil pump shaft they are made of cheap plastic and fail and break into pieces causing no oil to be pumped, creating serious motor damage
How did u replace the piston without pulling the whole motor out? I have to do a top end rebuild on a jetski of my own but idk whether to take the motor out or if I can do it while it’s in the ski
Most four wheelers and jet ski type motors, once you take the head off and then unbolt the cylinder, you just pull the cylinder up off the block and piston slides out the bottom
I bough the 2000 sea doo gtx need to rebuild top end . I’m try to do myself thank you for RUclips video Can you tell me Where you get the manual for jet ski? where you get the rebuild kit what size I need to get and where you send to machine shop?
I downloaded the manual online, as for the sizes to get the rebuild kit I’d call a dealership and ask them what size the stock bore is, then either replace it with the same size(if theirs not damage) or have it bored out. I bought my kit off Amazon
I looked up the factory specs on what the cylinder diameter should be, then I shopped around for an oversized bore kit since my cylinder walls were damaged and I knew I would need to bore it out. Once I found one, I called a machine shop to confirm they could bore it out to the specs I was buying and then I bought it
Hey do you still have your seadoos? I'm having a hard problem trying to find out where the hose goes that's on the block next to the throttle body. Would you know?
How do you know if it's low compression What compression reading are you at and do you have a reliable gauge because a lot of things on that Sea-Doo can cause it to be hard to start and you're just going to start throwing money at it so make sure you know what you're doing because they are very expensive I've been working on them for over 25 years
Jeez give the guy a little more credit than that! You must not have watched the entire video before you made your comment. Did you not see the completely trashed piston when he popped the cylinders off? And assuming that he didn’t do any diagnostic work on the machines just because he didn’t include the footage in this video doesn’t mean that he didn’t look into things enough to arrive at the decision to rebuild the top end.
I’m not sure what caused the cylinders to wear because I bought it broken, however I saw sand in the cooling ports and it looks like the pump sucked up some sand. Both skis also had pretty high hours so it may have just been old age
Hey it’s running but not for long if you don’t put water in that or sit in the water somewhere so I could suck it sucks water through stick a hose up at or something you better hurry up with the water hose
At the end of the video I run it with water, yeah I know how bad it is to run them out of water. Make sure to come back in a few weeks for the first test ride on the lake with them!
Hi Michael, I'm Dave and I picked up on your videos on motorcycles, checked out the rest and found excellent video and sound quality, great content and good presentation. As a 77yr old retired Army MSG living in the Philippines I watch lots of RUclips keeping up with life around the world. I like watching young people with ambition become successful. Check out Goonzquad and WatchJRGo two of my favorites. Do you have facebook page? I searched Lifebuilds and got hundreds of hits. Wish I could open dialog for suggestions rather than public comments. Dave Stoodley
I appreciate the kind words! Im a big fan of both of those channels, they produce great content! I haven't created a facebook page yet but if this channel keeps growing I will definitely create one and ill make an announcement in a video.
I have the exact same model, and mine is the same. Constant 12v low with draining battery and need new spark plugs every single ride. I already replaced the rectifier, now I'm hoping a new stator will fix charging issues.
Let me know, I usually get about 6-8 hours out of a set of plugs, I recently had one that will not rev, so I assumed that the fuel pump was getting tired, I changed the fuel pump and still acting the same, changed the plugs and no change,
Too much that has nothing to do with subject. Cars, skateboards, haircut..... nearly half of video before actually fast forwarding the actually subject. So time is wasted showing the Personal cars, and etc.

I had no idea, that makes a lot of sense though. Thanks for the suggestion, ill do that next time.
Very rarely that happens and that's why you don't turn the hose on full force.

I have always wanted to ride a jet ski! So inspiring!
Jetskis are a blast!
Great job! I am sure that was nerve racking.
Yes it was!
Amazing work sweetheart ❤️ Proud of you!
Thanks babe! I appreciate it!

you had it bored out a little bigger, did you have to modify the power valves so they didnt touch the piston or was it thin enough to not effect?
I believe they shaved the power valves a small amount but I don’t remember for sure
What did you used to get the bolts off of the mounting plate connected to air box nothing will fit in there?
Just a heads up, I searched and troubleshooted to find out why my pistons where scared up and why this is happening. Come to find out it's very common for the oil pump shaft to fail causing motor damage, my shaft was completely ruined causing no oil to be pumped into the cylinders.
That’s good information to know!

@@jl456 that’s not good lol
Another question I have is what did it cost you to have the cylinders bored out?
Just got one today and got some work ahead of me
You’ll have fun!

Where did you get your cylinders serviced? I saw you purchased these in PDX, not sure where you took them too though. Thinking maybe around PDX.
I sent the cylinders to get machined at pdr power sports in Milton oregon. It’s quite far from pdx
Great video. How many hours did it take you to tear it down and then reassemble the motor. I have a 1999 and a 2000 both needing top ends redone. Thx
I took it really slow to do everything right so probably 3-5 hours down and 3 hours to rebuild
can you show where to hook the water hose 😬 gonna rebuilt my first complete 787 engine and i will like to test with water
I actually already sold these jet skis so I am not able to show you how to hook up the water connect
ok no problem thanks 😃👍

I'm a little late to the party, how did you know to buy the 82.25 mm kit? I just got my first and also have never done a top end before. TIA

It had 30psi compression

Your obviously ignorant when you do a compression test and it's weak that's exactly why it won't start!
Hello,can you tell what was the cause of the wear on the cylinder?
I’m not sure what caused the cylinders to wear because I bought it broken, however I saw sand in the cooling ports and it looks like the pump sucked up some sand. Both skis also had pretty high hours so it may have just been old age
@@LIFEBUILDZchannel ok,tks.The my broken the cylinder number one and I'm not say what caused i think
In Brazil the piexea are Very expensive,the shirt, pistons and rings cost Us 500
@@richardmanfredini2337 shoot that’s a lot for those pieces, I got my kit for half that price

What was your torque specs?
I don’t remember, I believe you can Google a factory service manual and that’s how I found it originally
@LIFEBUILDZchannel I'm getting 60 psi on one cylinder on 90 psi on the other and now it won't start at all hoping this is what it needs.
@@jl456 yes I would guess that it needs a top end rebuild
@LIFEBUILDZchannel I'm working on mine now, how did you get the bottom exhaust manifold bolts off did you remove the throttle body?
@@jl456 I believe i removed the throttle body to get access to those bolts. As for the machine shop I paid a bit over $200 to bet it machined
what was to total cost with the machining and parts
It was around $500

Hahaha thanks 🙏
JUST WONDERING IF YOU HAVE LOW 12V ISSUES? ALSO, MINE GOES THROUGH SPARK PLUGS LIKE EVERY 5 HOURS, LET ME KNOW, I ABSOLUTELY LOVE THEM
