I have always wanted to add a flush kit to my jet ski. After all, I always flushed my boats after I ran them, but stock skis never came with a way to flush them out. The solution, of course, is to buy an aftermarket flush kit!
If you use your jet ski, you need a flush kit! Flushing your ski is a must if you run in salt water, but did you know that running your ski in fresh water (like your local lake or river) can cause premature corrosion of your internal engine components? Lets put it this way, would you drink lake water? So flush that shit out of your cooling passages, this is one piece of preventive maintenance that everyone should do!
The Polaris flush kit will run you about $30 at your local dealer. It consists of four parts, and are they ever a snap to install!
