At the advice of my Yamaha mechanic, I am using the Yamaha 10 micron water separator filter instead of the Racor with the sight bowl. He gave me an explanation why the Yamaha was better but I do not remember what he said. All my buddies are using the Racor with the bowl but that filter looks so small compared to the Yamaha.<br /><br />What is the advantage of using the Yamaha filter? If you see water in the bowl of the Racor is it too late? I have also heard that when the filter gets full, water will pass through to the engine, correct?<br /><br />Thanks,<br />HH
