If your boat runs in Brackish or Salt Water. East Coast Powder & Ceramic Coatings has the fix for corrosion. We completely stripped this 1 piece adapter plate and prepped all surfaces. Applied a nice coat of 2000 deg ceramic to the Exhaust ports and all water cavities'. Then Tapped everything off and applied a fresh coat of Mirror Black Powder. All our ceramics and powders are specially formulated to withstand Marine salt Environments. They are tested to ASTME standards and subjected to 2000 hr's of Continuous Salt spray before being approved.
