I have two 2014 Sea Doo GTX 260is limited. One of the two had milky oil (water in the oil) from a bad intercooler when I purchased. I don't know how long the water was in the oil prior to my purchase, but I cleaned it out as soon as I bought it. Multiple oil changes later, and with a new intercooler, the oil was pristine. I cranked her up and rode for about two hours. The next morning I rode again and after about 5 minutes the engine shut down and would not restart. I got a tow in and took her back home. Long story short, I lifted the valve cover off to find the timing chain broken. I have since learned the timing chain is the weak link in this engine after water ingestion. The water in the oil caused pitting and corrosion on the chain which weakened it and finally caused it to fail. The carnage was widespread: broken intake side rocker arm, 8 of 12 valves bent, bent piston rod, and a scratched up piston. My point is a broken timing chain may be in your future. If for some reason you need to go into the engine, replace the timing chain. Even if you don't need to go into the engine, replace the timing chain over the off season. The new chain will save the carnage, the headache, and the expense of rebuilding the engine. PS: One week after I rebuilt the engine, the throttle body went out. Replaced that and now she back to running good as new.
@@SwampBoysGarage I'm no pro either. I learned the why regarding the above watching Ernesto on the Calas World channel. Awesome seeing father and son work together on a project. Many good times and best of luck to both of you.
This advice is maybe too late, but you are figuring out that Seadoos use coolant for engine cooling, but river water for exhaust cooling. The water in the exhaust is normally blown out when you flush the ski with the engine running. So just make sure you get water out of the intake - the water in the exhaust will naturally blow out when you start the engine. I am a little concerned the exhaust muffler or box could have split from the freeze, but you wont really know until you start it with a hose connected and see if water leaks into the hull. Whatever you do, dont turn your hose on until the engine is running, and turn the hose off before you stop the engine. You will fill your intake with hose water if you dont do it right. Watch some you tube videos of how to flush a seadoo before you start it. When my seadoo sunk, i idled for 2 hours around the lake with the oil cap off to boil all the water out and get oil clear, and then changed the oil one last time. I had to change my fuel injectors due to water exposure, ran poor, but i had salt water in my engine. Been running great since though, and that was 3 years ago. You might also need injectors too. But your electronics all seem good, which would be my biggest concern with a salvaged ski.
Another secret for your next flooded ski - you typically don't need to take off the intake to get the water out. Just remove all the plugs, and put a wet/dry shop vacuum on each cylinder hole while you crank over the engine. Crank for 20 seconds or so sucking water out of each cylinder. Repeat process for each cylinder 2 or 3 times until all water is out. It will suck your intake dry - works great! A master jet ski tech gave me that advice when my ski sunk.
Add a bit of oil or Marvel Mystery Oil to each cylinder. It will assist in the lubrication of the ring of the cylinder. Cycle it over a the compression should come back to normal.
You have a new subscriber guys.I am going to buy a Sea-Doo from Co-part this year so this video is very informative.Thanks for your time
Awesome

Appreciate that info. We are not pros and learning as we go.

Can’t wait to see the next one! Will it run?

Appreciate all that great info. That helps us a lot.

Not far enough in the process of drying it out to be doing a compression test.
Good video. I enjoy the content you guys are putting out.
Thank you. We try to make good content
This is totally interesting to watch.
Knowing 0 about jet skis, this is Class101 on brining a Submarine back to life!
101 for us too but we love learning new things.
I thought the fiber glass repair would be done by now. Did I miss a video
It should have been done. Been very busy with school and track and dad has been working. Will be done by this weekend hopefully.
That water is probably from it sitting outside all that time. You did great with the compression. Just make sure next you wear safety glasses
I always forget some kind of safety gear. lol
@@SwampBoysGarage I just didn't want that hot oil getting in your eyes
Whoever is watching this video, I hope this day will be a great day.
Wow, your Walmart is actually stocked. Ours looks like it's going out of business lol. What year is this jet ski?
It’s a 2018
Thanks!
Love the new intro.
Thank you

I been shooting kroil in the cylinders.
Pretty exciting! I'm hoping it's as simple as it's looking so far!
Always hidden damage.
Short video but good one👍👋
Thank you.
Hopefully you guys can get your Sea Do running and take her to the lake for a test run.🤠👍🏻🍻
I hope so too. May have to just part it out on eBay. Not sure yet.
@@SwampBoysGarageNooo🥺 don't part it out and do some research for a good used engine on line😊
