Yamaha - Internal Crankcase Anode Kit - F350 XCA, UCA, AET1X, AET1U Corrosion Protection

Overview

On the F350 lineup, especially these larger offshore models, internal corrosion protection is something you don’t want to overlook. These anodes are built to take the corrosion hit before it reaches critical engine components. Over time, they wear down doing their job, and once they’re gone, the engine becomes the next target. Replacing them along with the grommets is simple maintenance that helps keep your motor protected and performing the way it should.
