I know that this is not a new topic and it has been discussed before. I Just pulled he lower units on my F225s mounted on a 2003 Marlin with 700 hrs. on them for the biennial water pump replacement. I'm trying to decide if I have the corrosion plague that has been discussed frequently on this board. Attached are the pictures I was able to get with my cell phone. I think the corrosion is not too bad, but I am seeking opinions from the Yamaha experts out there. I boat in cold water New England, and was told that corrosion in the dry exhaust is mainly a warm water problem and is also due to poorly running engines. Of course the material problem is always there
