Anyone found a product that will keep the white rubber rub rail insert clean above the transom protecting it against the black exhaust soot?

The white rubber rub rail around the transom gets covered in black exhaust soot. I trailer the boat and clean it at the end of every weekend with black steak remover, magic eraser, and acetone but it still starts to yellow after a season or two. I have another new insert to install and would like to prolong its bright white life.

I don't know which engines you have. But, if you have the 496HO's, there was a flash update in '03 which resolved a large part of the soot issue. I went from having a black transom every time out to just a light film after the update.

Whenever I have a mark on my rub rail that can't be washed off, I use 400 grit sandpaper. Works like a charm.

I use a litle carb cleaner ona rag and it will clean it right off

plum crazy,could you give me soom info on the flash up-date,I have a 2003 ,358 sonic,thanks

Contact Mark at Precision Marine(pmefi.com). He'll want to know your ECU revisions and SN's.

peteandbetsy, could you post when/if you find something out, I too have an '03 358 and would be curious as to what you hear. Thanks in advance.

As I understand it, Mercury had to correct the voltage to the fuel injectors.

I use some laquer thinner about once a season and run over it....seems to clean it up well.
