Cavitation Part 3
Hey everyone so today I pulled my ski apart in preperation to have the pump show replaced. In the process a few things caught my eye... I was pulling everything off the shoe and noticed that yellow gasket with a washer in it. It looks like it restricts water flow... what would happen if you remove the washer or just make the hole bigger? More water is better right?
Another thing I noticed is when I removed my driveshaft oil started dripping out of my motor. Is this normal? I am hoping it is
Another thing I noticed is my carbon ring. It looks great to me. Included are some pics. Anyone see any problems with it? I already ordered a new one but I was just wondering if mine is bad or not. It does not look bad.
And last but not least... when I pulled my intercooler off there was some water in it. I last rode in saltwater and did flush the ski. But as you can see fromt he pics there are salt deposits in my intercooler. Does this mean I have a leaky intercooler? It is new and has about an hour use on it.
Thanks ahead of time for all the help guys, I really appreciate it!

That yellow washer is your restrictor plate. You don't want to remove it as it will over pressure the IC/exhaust system and could cause a hole in the IC.
Some people drill it out one drill bit size bigger when going to an external intercooler. This is fine.
It's normal to have oil leak when you pull the driveshaft out of the engine.
The deposits in your intercooler look like normal salt air deposits. Intercoolers have a pretty good amount of condensation and if you ride in salt air environment this will happen. If you had a leaky intercooler you would know it. It wouldn't rev past 6400 RPM's or so if the leak was bad enough. It would sputter a lot.

The stainless steel floating ring needs some attention. Dress it and the carbon ring with some 300-400 wet-or-dry paper on a flat surface or replace it and replace the carbon ring and o-rings too. When re-assembling use silicone grease inside the pto bearing and the floating ring on the o-rings but do not get any on the carbon ring and floating ring face.

Thanks for the info on the ss ring... I will just replace the part. My goal is to make sure this thing does not cavitate once I get all the work done to it. To much headache taking everything off and putting it back on.
