@@Platypus_Warrior oh definitely! But the fact everything is still that great of shape and so little corrosion is amazing no matter how good the service was. And rental units of anything get the piss beat out of them.
Amazing that that thing had almost 900 rental hours on it. Clearly the company that owned it must have followed a pretty rigorous maintenance schedule. I’ve now increased my expectations for my machines! Thanks for documenting and sharing your work!
Thank you. I've never torn into a seadoo before and got a great offer for a 2017 with almost 900 hours on it and now I have a general idea of the mother layout. Should be a fun winter project.
my spark 2018 blew the piston out the bottom side, 52 hours was good and first 15 minutes of riding it in lake water the second time it blew.. I only rode it once before and made sure to clear the hull of any water afterwards. Tearing it apart now to see if some of it is salvageable.
I thought I already responded to this comment, but can't see it. It makes me wonder how suitable it really is in an engine. Doesn't sound like a good long-term strategy, but the engine internals sure looked good.
I guess not bad considering a well taken care of outboard can go for over 3,000 hrs with no problem. It seems that this engine had a long way to go if it was washed down externally a little better and even hit with TFE protectant. I love jet propulsion engines so it's cool to see. Yamaha is next for me.
Wonder what kind of oil it was...I'd like to run it in my 2018 RXT-X 300 because that engine was really really clean for so many hours on it. Kind of wondering if was rebuilt sometime recently.
We think they used the recommended Sea-Doo semi-synthetic oil. The red colour is probably due to staining over time from the marked (dyed reddish), marine gasoline.
As someone who works on these everyday for the past 12 years, the reason why this looked so good is because its the a 130, and it’s probably have a Rental tune that reduces even more power to save fuel. Tear apart a SuperCharged one at 180 hours and there’s a hell of a lot more wear and tear. The 215’s had so much blow bu problems around 150 hours many wouldn’t stay running.
Hey, thanks very much for the feedback. Any idea what that reddish oil is? The best explanation we’ve heard so far is that it is stained red from the marked fuel.
Those oil pumps always look like that. Really good for 800 hours compared to others I’ve seen. They’ll look like that if u put a brand new one together and spin it a few times it’ll still have those marks after. As long as you can’t feel them.
Excellent video. My purchased new, 2008 RXP is sitting at 226 hours. I’m impressed that so many hours went into that ski in such a short amount of time.
Great video! Maybe someday tear down a salt water high hours Yamaha 1800. I flush mine religiously and rinse engine bay after every ride but always curious how the salt water could be affecting it. But 2 years & 220hrs later still runs like new. Anyway your videos are great for learning the disassembly and assembly process. Question: any idea how often I’m supposed to replace the anode on the engine block?
I use Mobile 1 full syn. in all my bikes ,cars, and Seadoo. My GM pickup is nearing 600k, and the motor sounds great. I got turned on to it , when we used to use it in the jet aircraft engines at work. I worked as a mechanic for Eastern Airlines back in 80's. In the jet engine, it goes in the gearbox, an gets pumped up to the turbine bearings, and thru out the whole engine. I change it every 100hrs. on the Seadoo like my manual states to do. Your engine is wearing down every hour it runs, might as well use the best oils to slow it down a bit.
Vcs Sao fera os vídeos que vcs fazem Sao de muita ajuda pra nós aqui do Brasil poderia me enformar com quantos quilograma força é apertado esse cabeçote des de já obrigado

this makes me feel so much better about buying my ski. it was an ex rental with 365hours on it. been serviced well and it honestly still runs so damn well. they did tell me they have others with near 1000hrs and still going well. great video mate
Wow this is incredible! You guys seem to really know what you are doing and I can’t believe how good everything looks. Do you think the supercharged skis (RXTX/RXPX) would last to 800 hours too? I am not sure if I want a seadoo or a Yamaha. Do you have any recommendations? Also how much did it cost you for all the parts to rebuild this machine?
Yes. If they're properly maintained, they should last 800 hours. The supercharger needs to be rebuilt on all models (except the 300 HP machines), or they may fail and cause catastrophic engine damage. Also, the intercooler on those machines need to be monitored, as they can leak and also cause engine damage. If those two systems are regularly maintained and repaired, the engine should last. Thanks for your comment.
@@3ftDeepChannel Excellent work! What year had the intercooler issues? My 2004 RXP has the intercooler in the Intake manifold. Was it that type or the external that would leak? Thanks! ** I’m also about the tackle the exhaust valves too…any tips?
Actually, the internal and external intercoolers have had problems in the past. Just keep an eye on the oil (after every ride) and look for any signs of water intrusion. If so, it’s likely the intercooler. As for the exhaust valves, just make sure you seat the new ones properly with lapping compound. Good luck.
and now you know why a GOOD jet ski mechanic (if you can find one) charges what they do. How people learn this is beyond me :) But I can see a nice living once you do learn.
It’s funny this just popped up. There’s a 2016 GTI 130 for sale local to me from a rental company. It has 690 hours, new starter,relay,battery,bumper,grips. It was a fresh water ski used with the rental key so no full throttle. He’s asking 4.5k for it. Was going to ask if you think I should get it and if it would be a good buy for a first ski. Would really appreciate your input! Thanks
You should check it over following the advice we give in a previous video about how to buy a used personal watercraft. I wouldn’t worry too much about the hours on the machine, as we found out, but the resale value will remain very low no matter what you do to it. So keep that in mind. Good luck!
@@3ftDeepChannel thanks for the reply! I will check out the video you recommended. As for the price what are your thoughts on $4.5k. Is that to much or is that pretty fair? I know you don’t want to give the price of this project but if you were offered a 2016 gti with 690 hours for $4.5k would you take it? Thanks
Without giving away the price that we paid for our machine, I would offer a little bit lower than that price. Of course, the market is very different now with such a low supply of machines worldwide. Today, I would be happy with $4,000 Canadian assuming there weren't any obvious issues. Good luck.
5:38 "4 thou, 3 thou, and 35 thou. So that's, the 4 thou is right at the edge of the service limit." If the .004" was the only one close to or at a problem then it wasn't .035", it was 3.5 thousandths as was written on the pistons.
We were never able to get confirmation, but there have been a number of good comments regarding possibilities. There were a few suggestions for the oil, and some regarding red dye in marine fuel which may have stained the oil. I’m not sure about the red dye though, as it should have been flushed out with regular oil changes (assuming they were done).
Excellent video. I already felt pretty good about my 2019 GTI 130 former rental with 300 hrs. It is much better shape than my 2012 50hr GTI. Maintenance is key. Low hours can be bad if not maintained.
That would never happen while we’ve got the workpiece on the bench and easy to work on. It would wait until it’s inside the machine, impossible to get to, and while we’re on vacation far away from our tools ;)
Wow! Your videos are Awesome! My 2005 RXP recently blew up with only 149 hours on it. Pretty disappointing considering the hours on the engine in this video. I haven't pulled the engine yet, so I don't know the extent of the damage yet, but when I was riding I heard a bang (similar to a belt blowing on a snowmachine) and it just coasted to a stop. There is oil on the bottom of the hull and I also found some chunks of metal below the engine. Do you have a website or number I can contact you to ask a few questions about my Seadoo to determine if you think it is repairable?
Hello Brock, Sorry to hear about your ski. It could be the supercharger, if it hadn’t been rebuilt. That’s a common problem in machines of that year. Feel free to send us any pictures or questions, etc. by email at: 3ftDeepSports@gmail.com, but we prefer to have as much discussion in this forum, as others also get the benefit of the chat. Oh, and thanks for the kind words.
@@3ftDeepChannel I don't think it was the Supercharger. I took it out and had it rebuilt immediately when I bought the machine. It has right around 100 hours on it since the change, so ironically I was planning on pulling it this fall (now) and getting it rebuilt again. I have been reading a lot about bad valves in the pre-06 machines as well. Do you think that could have been the problem? I am scared because my wife has the matching machine with about 100 hours more on it, so I don't want to end up with two blown machines.
@@3ftDeepChannel 2004-2005 models had a lot of issues with valves rusting and then dropping while in operation. Like the supercharger rebuild, valve replacement is obligatory when buying one of those if it hasn't already been done. The issue was corrected on newer models.
Yes, we did a valve replacement in an older video for that very reason (preventative maintenance). We always check the valve numbers when we’re in the engine to make sure the good ones are in there. Thanks for your comment.
Thanks for mentioning that. We put the torque units in the how to videos that are more instructional. In these ones we are just troubleshooting, or tearing into interesting projects so we don’t repeat the torques that we have mentioned in other videos that are specific to engine components, etc. Thanks for your comment.
With this machine it didn’t take too long. Probably six or seven hours once it was out of the machine. But more problematic machines can take 10 hours or more.
That's a good question. But if you keep up the maintenance on your machine, and only put on about 14 hours per year, I doubt you'll ever run into any engine issues. Safe riding.
More stress typically equals more wear, but maintenance matters. With things like jet skis, exotic cars, motorcycles, etc. too many people let them sit forever, don't keep up with the maintenance (it sits most of the time, why would it need it) and then expect that they can go and beat on it once in a while and everything will be fine.
Are you from revenue Canada? Just kidding. I can’t tell you what we paid for it, but it was relatively cheap because of the condition it was in. If I recall, we put in about $1800 in parts, including a new seat cover. We made a few hundred bucks on it at the end of the day, but if you count all the hours we put into it…
Awesome.. the more u you use a marine engine the longer it will last. Worst thing for any engine is not using them! My yamaha vx1100 has 1050hrs on it.. brought as ex rental at 750hrs 7 years ago and still running great! Just oil changes and sparkplugs every 40hrs or so..
It got a lot of use... if it wasn’t maintenanced well it wouldn’t had made it to 900 hrs in the salt... so unfortunately I guess I can’t say “rode hard, put away wet”
Honestly, rentals are typically more maintained than regular owners. I know several people who dont service their skis other than oil changes. Then I am close with a ski rental shop and their in house mechanic works on solely servicing the rental units. Those units are sold in better condition than many skis on the market
Oil spray nozzles AKA piston cooling jets. Common on diesels. It was nice of you to take a perfectly good engine apart for us to be amazed at it's good condition!
I was going to purchase a new gtx limited 300hp. I noticed you said the supercharger doesn't need to be rebuilt on those? Did I read that correctly and why if I may ask?
@@ViolatorZ06 The superchargers got steadily better over the years. They were upgraded to metal washers from the ceramic ones, which increased the rebuild time to 200 hours over 100. 2017 and up models just call for an inspection at 200 hours. Caveat is if something is wrong you replace the unit instead of rebuilding it.
Nice video. When I rebuilt my 155 GTX I used my own ball hone with good results. My piston clearance was a little high and I had the skirts coated which gained back 0.001" OD and provided some additional wear resistance.
As the owner of two 300 4tec motors, I loved seeing the shape of this engine after so many hours. Rotax sure loves E Torx bolts. I noticed that you did not replace some of the components that were still within service limits. I'm fine with that, but I expected you to replace the valve stem seals. It would have been more work to break the head down, but with that many hours and new rings....... Love your videos, very well edited. I have the shop manual, but seeing the actual work done really helps the perspective.
Thanks for your comment, Tracy. We didn’t really consider replacing the stem seals, as they also appeared in good shape. You do have a good point, however, as we were already in there elbow deep…
That’s a good question. It doesn’t really improve much by cleaning them up, so it’s really up to you unless they have a lot of carbon buildup. Thanks for your comment.
Did you end up replacing the oil pump parts that were scored? Thank you for making the vid. I’d also probably replace that damned carbon seal while you have everything apart.
Great video, one thing I noticed is the tensioner should go in before the cam bolts are torqued. This sets the cam gear to the correct advance, probably wouldn’t be noticeable on a NA engine but could alter the performance.
Great video, I have a 2019 fishpro with 240hrs, I run offshore 70 80 miles and I maintain and clean my engine really good, my only concern is the starter, how long will it last and do I have to pull the engine to replace. I start/stop quite a bit and if starter goes out there is no way to get home
I haven’t heard of a starter going on any of these machines. We know of people who've replaced them before, only to find out that they weren’t the issue. They are, however, extremely awkward to remove from the engine while that is still in the machine, but it is possible. You will wish you had an extra joint in your forearm, though. If it were my machine, I wouldn’t worry about the starter motor. Good luck.
I just replaced the starter on my 2014 gti was a rental with 748hrs on it. Paid 1500 with trailer because they said the engine was seized. Ended up just being a worn out starter from trying to crank with a rock lodged in the impeller. Mine would start once every 4 hours before I changed it, now it starts everytime. If you have slim arms its quite easy to take out and put in. I removed and replaced mine in 15 minutes.
Thanks for your comment, Brandon. You must have very special arms to replace your starter motor in 15 minutes. Both Chris and I have struggled with ours for at least an hour to get it out!
I used to work at a Kawasaki/Sea Doo shop in the 90’s and back then it was common to see Pierson all watercraft come in that were in terrible shape after just one season. They would have been sunk or they would have been left for weeks full of salt water. The engines would be solid corrosion! I wouldn’t buy a used PWC for anything in the world. These 4 stroke boats must be better built then back in my old days. This one is in surprising shape.
It had a lot of exposure to salt water (it was sitting in it for 2 years), and had lots of corrosion due to the exposure. Whenever we ride in salt water we always thoroughly rinse with fresh water afterward. A little spray lube on the metal components after also helps to minimize corrosion.
Definitely not afraid to purchase a high hour machine now. One question, why were you guys using a torque wrench on basically every bolt and then 3 of the most important places to use a torque wrench, one of them the head bolts, you go and use just a breaker bar? Your going to have uneven pressure on the headgasket and potential for it to leak... what up with that. Also the tightening of bolts in a sequential order all the way around instead of in the proper pattern got nerves going haha
We always use the proper torques on all engine components, except some of them require a torque and an angle. For the angle, we estimate it while using a long breaker bar to get enough to work. Thanks for your comment.
Everything uses torque angle now. So for example you will torque a bolt to 30lbft plus 90 degrees instead of just torquing to 80lbs like back in the day. It’s easiest to gauge angle with a breaker bar since it’s solid. They do this because as torque increases so does friction, and that 80lbft is measuring the force it takes to turn the bolt, not necessary the clamping load the bolt is applying. So by torquing to a low number, then a specific degree of rotation you get a more accurate and consistent torque
Well, like we've been responding to other similar questions, we dug into this to see what the condition of the engine was, not to rebuild it. So, we only changed components that needed changing. Thanks for your comment.
I have a 2013 Seadoo GTS130 rental with 1060 hours and I recently took it to my local Seadoo dealer. They were amazed how good it runs and amazed that still has strong compression. Also the jet pump was in great condition. They told me they were surprised it had 1060 hours by looking at the ecu data. I thought it had 360 hours as the cluster was replaced sometime before i bought it. I am amazed at how good these engines are if you look after them with regular servicing. And yes! it is all original! Seadoo confirmed that.
That’s great to hear, Daniel. I have heard that they can go two thousand hours without having issues. I’m starting to believe it. Thanks for your comment.
@@3ftDeepChannel Wow that is incredible. I also know this jetski has lived its entire life in salt water. I use almost every weekend traveling between islands and it goes very well, has never let me down.
guess that "crazy red oil" worked pretty darn well! bearings still good after 893 hours! Where was that SEa-Doo used? The Northwest? I'd love to see one with 893 hours from Florida... my 2016 has 100 hours on it in FL heat...
Exactly. That machine was a rental unit used exclusively in salt water in the Pacific Northwest for 2 years. In fact, it never came out of the ocean in 2 years! Given your location you need to rinse the inside (including intercooler and exhaust flush) with fresh water thoroughly after each ride and wash the outside as well. Good luck!
Red oil. Marvel Mystery oil perhaps? Looks like it. I put a bunch of it in my old 1999 Yamaha and let it sit over the winter. Just removed the plugs and put some in. Then took it out for a run in the spring. I could not believe how much better it ran. The pick-up and power was so much better. Now just add it to the oil reservoir. @@3ftDeepChannel
Hi is Tim I have a 2010 rxt 260 Seadoo rebuilt engine rebuilt supercharger replaced Beaufort harnesses complete overhaul new computer only running 45 miles an hour is the any tips to test any think of what's going wrong
great video nice to see the ski had good maintenance was surprised you didn't change the bearings and oil pump gears just for the sake of it being apart even though they were in good shape
Good point. We were on a tight budget, so trying to keep the parts cost to a minimum. As they didn't need replacing at this point, we opted not to do so. Thanks for your comment.
I’m not sure what scene you’re referring to, but some of the screws in the engine require a specific torque followed by a further torque of a specific angle (i.e. not force).
@3ftDeepChannel interesting. Never heard of that before. But I'll take your word for it as I haven't wrenched on these types of motors before. Looks like it ran great after all your work. 👍🏻
@@3ftDeepChannel I truly don't understand why the 2 strokes are less reliable, they are so simple. I have a 717, 951, and 2 Yamaha 700s. The Yamaha seems to be bulletproof. But even still I had to pick up a new 4 stroke. Was tired of Constantly fixing them.
We haven’t had much experience with two-stroke Yamaha’s, but the two stroke Sea-Doos were requiring lots of maintenance and we’re becoming very, very unreliable. And when you’re in the ocean…
Well, it’s hard to quantify but the resistance should be considerable. There should be no binding, though. The resistance will be even higher if the spark plugs are in.
Really, you should apply it as if it were a gasket all the way around the surface for best seal, but as long as there is a barrier all the way around unbroken, that is the main thing. Thanks for your comment.
Yes, you can see the results in part 3 of the series. Around the 4:55 mark we compare the two results. It is a bit confusing the way we organized the video. Thanks for your comment.
