Corrosion on adaptor plate Mercury EFI 50. Which models are affected?

[larsen2000]

I am looking for a used Mercury EFI 50/60hp but I understand there is a common problem with corrosion on the adaptor plate. Any who knows which year models that are not affected? As far as I know so far I should not buy year model 2001, 2002 and 2003.

I have tried contacting Mercury in three countries, but they do not answer phone or e-mail...

From 99 to about 2003 they had issues. You can always get the serial number off the engine and run it through Merc-net.

What is Merc-net? I need to know if I can buy year model 2004
