I know it’s a long shot but if anyone wanting to upgrade or know where a new/used F250 25” shaft is let me know ASAP. Buddy of mine had one go bad due to the corrosion issue.

What's the corrosion issue ?

Internal corrosion in the block and midsection, extreme pitting that can eventually eat through the block or exhaust areas. Somewhat common on certain Yamaha motors from around 2000 to maybe 20010, nit sure on dates. Search on thehulltruth.com for Yamaha corrosion and should be able to find more info and pictures. Had something to do with the aluminum alloy they used.

The big four strokes built in the early to mid 2000’s had internal corrosion from the exhaust. Lot of lawsuits to Yamaha but they were thrown out of court. They did send the replacement parts but had to be fixed at your expense, which wasn’t cheap.
This was an attempt of a patch

I wonder if a "Salt Away" rinse would have prevented the problem? I do that religiously with my two new Yammys and I'm planning (and hoping) to get many years of service from them.
Evidently not.....see below.

"salt or fresh some of them get the yamarot. mine was operated at the end of every season in a fresh water lake in pennsylvania. it was also flushed after every use to no avail. i later found out that the coating in the exhaust stack was sub standard. the area that rots out is dry and you can't flush it. it is the corrosive nature of the exhaust gasses that blows the coating off. yamaha offers the repair kit and no other assistance. the class action was also dismissed so owners are pretty much left to their own solution either fix/replace the motor.
