I am new to PWC, I have always owned boats but this is our first PWC. So take it easy on me. Where/how do I install a flush kit for my FX140? I am ordering a manual, but its not here yet. I saw a flush kit online.....I believe the kit was around 40ish does that sound right? Also once this is installed does this mean I just hook a hose up to it....then start it up and let it flush or run for a while? Any help would be appreciated.
