What you called salt deposits was likely aluminum oxide or corrosion. Salt will dissolve immediately when in contact with water. Sounds like you might want to flush with fresh water after every use.

The aluminum plug to replace the steel one can be bought from g o l d plug.com . Send them an e-mail and tell them you want the aluminum plug for the DF 140 Suzuki. They will ship it to you. Eliminate the spaces in the web site address. This forum will not allow the word g o l d. What is that all about?
