2010 Kawasaki JetSki STX-15F Overhaul - First Ski

[mdmay62]

It's been a while and not a ton has been accomplished. I've been working on building up some funds to keep building. This week I was able to get a new impeller in and finish the pump rebuild.


I am still also working on getting the broken spark plug threads out of the head. I may end up pulling the engine and doing a rebuild soon just to get the spark plug free. If anyone has any suggestions to get the threads of a spark plug out of the head hit me. The threads are all that is left the electrode came out along with the first 1 or 2 threads it broken off just below the nut.

Well a short winter break and some home improvements and I'm back to working. Since the pump rebuild I've been working on the engine and a few other things. First off, I finally decided to drill out the spark plug so I pulled the top end of the engine out of the ski and cleaned up the head. Next I pulled the cylinders, cleaned them up and sent them out today for re-plating, hoping to have them back in 6 weeks. Today I also got the drive shaft out in preparation to replace the driveshaft seal and bearing. I've been working on waxing/polishing up the hull as well trying to get that looking better. I'm almost ready to put the stabilizers back on. Finally I got some rivets to reattach the right rear corner bumper and a new nose bumper to install as well as a new kawasaki deck decal.

I put that blue marble HydroTurf in my blue Yamaha Exciter boat. It looks awesome!

I do love the way it looks on the ski, not what I was planning on at first but happy I wen that route!

Still waiting on the cylinder to come back so I've been slow moving on some other stuff. Last week I ordered a new intake grate since I broke mine trying to free it up and yesterday with a little convincing and heat I was able to get the broken piece off.


I tried to use the same method used to restore the stabilizers on the reverse hood however it was not a success so, I decided to throw some paint on that as well to make it look new again.



I was also able to get the hood painted to the new scheme, I'm not super happy with the way it came out but it will do for now until I know I can get it running, I'll recoat in the offseason to get it looking perfect.



I started cleaning up the hull inside since I have the engine out and I was able to rebuild the driveshaft bearing/seals. On order I have new piston rings and a gasket kit so when the cylinder returns I can jump right into the rebuild.

I'm also trying to find the best way to get the white out of the black bottom, if anyone has a good trick to this, I'm open for suggestions!

I was just poking around on here recently and found a thread that almost sounds like my situation to a T, hopefully it is piston rings like this. It was a little worse for me though because the Nikasil was coming off the cylinders so they needed to be replated.

Post number 22 gives similar compression as to what I was getting when I did the compression test.
