Yamaha Oil Injection Pump Assembly - 6R4-13200-02-00 Yamaha Marine 4-Stroke Outboard Thermostats 25" x 17 Pitch -Yamaha Oil Injection Pump Assembly Lubrication System Component 6R4 13200 02 00 Overview With two stroke motors, the oil pump isnt something you gamble with. Ive seen engines look fine on the outside but suffer internally because oil delivery wasnt right. When this pump is working properly, everything stays protected and the motor runs the way it should without extra smoke or wear. Its one of those parts you replace before it becomes a bigger problem.
