I have a 2009 F250BTXR Yamaha and need to replace the engine anodes. I found the 2 on each of the cylinder heads where the spark plugs go and they were pretty bad. Engine has 350 hours on it and don't think they were ever replaced. Where are the remaining 7 anodes located? The drawings show them but kind of difficult to know what I have to remove to get to them??
