i've recently acquired a mid 90's yamaha waverunner and would like to start it on the stand. it's my understanding that there needs to be fresh, clean water running thru the system while this is done. where does one hook up water supply for this?
You may need a flush kit. Basically just a hose that will attach to your garden hose on one end and to the port on the engine on the other. What model is your ski. Some have 2 flush ports and some one. Some skis already have the port under the seat and all you need is a special hose to attach it to.
