Yamaha - Oil Tank Assembly - Oil Storage & Delivery System - 6E5-6775A-00-00

Overview

On oil-injected Yamahas, the tank is something you don’t want to overlook. I’ve seen cracked or contaminated tanks cause air leaks or oil delivery issues that lead to bigger engine problems fast. This assembly is what keeps a steady supply of oil feeding into the system, so it has to stay clean and sealed. When it’s in good shape, you get consistent lubrication and one less thing to worry about on the water.

Key Features
