I do not have serial number handy. But I have a 2006 model year 225 PRO XS. It only has 215 hours on it. I had the plugs replaced at 120 hours. I was going to have the dealer replace when I have my water pump done. The manual says inspect and replace as necessary after the first 100 hours. Does everyone replace the plugs at every 100 hours? Somewhat pricey to get this done. However just looking for best practices.
Thanks
Richard
