Doing some reading up on Yam maintenance including the maligned VST. Making sure I am understanding what I see in my parts diagrams. Is the VST the housing for the fuel pump? Or is my 09 got a different set up? Also, would it be good to go ahead and clean the tank and replace the filter as preventive maintenance? I have owned the motor for two years, it runs very well. Another thing, I have been looking at getting the Yamaha mini Fuel/Water separator unit. Is this a good unit, or is there a better 10 micron filter the gurus of iboats would recommend? Thanks for your time. This boat and motor was a big investment and I want both to last a long time.
