Newbie question here - I searched for a while but couldn't find an answer so please don't yell at me! I bought an '04 SJ and it has a hose in the engine compartment with an attachment for a garden hose. What is the proper procedure for flushing my ski using this hose? Is it engine on -water on - water off - engine off? Do I rev it up while the engine is running? Also, when I'm done riding (fresh water) and load the ski on the trailer should I be starting the ski and running it until water stops coming out of the exhaust? Thanks!
