boat name stained from diesel

[saltshaker28]

I have vinyel lettering on my boat that was put on 2 years ago and it seems to be stained from the diesl smoke from my yammar 315 that does not seem to smoke at all for a diesel did anyone ever have this problem and if so how did you fix it

Diesels make soot. Period. No way to prevent soot in the exhaust.
An extension may get it past the transom.

Is there anything you can put on the name to protect it

Try Rejex. It won't prevent the soot from sticking completely, but it will make it much easier to clean it off. The stuff was originally formulated to help prevent soot buildup from jet engines.
