Seems pretty serious.

HMBJack said:I read this and was concerned so I called Yamaha and discussed it with them. They said simply "Flush your engine after every use in salt water". If you don't flush and have a 2003 F225 or earlier - you're asking for trouble.
Note there are thousands of F225's out there and they all aren't failing due to corroded exhaust manifolds. Agreeably, 2003 F225's and earlier ones are more exposed to salt water corrosion (the 2004 and above models have better paint and coatings). However, with regular flushing, you should be okay. No need to fret about it. Use the thing and if you experience overheat conditions NOT related to poppit valves(aka PCV) , thermostats or water pumps - then you (and I ) will cross that bridge when we come to it... Good luck!

Thats crazy. Sorry to hear this. I hope Yamaha makes this up to you, 6k? wow. How many hours do you have on the engines? 2004 engines?Fintango said:I have a 33 Express with twin F225s and recently had dry exhaust corrosion on both engines These are 2004 engines and flushing would not have prevented the problem as it began on the dry exhaust side and rotted over into the wet cooling side. The first hint was a low speed over heat alarm and while I haven't gotten the bill yet it appears to be in the 6k range. Yamaha will do nothing to help. The new parts have a different coating on them so I suspect and hope the problem has been fixed. Fingers are crossed. I am very disappointed in Yamaha's response. It was clear that they were aware of the problem but were doing nothing to help their customers.
