I have a 175 Mariner EFI Magnum and a Yamaha T8 4-stroke Kicker motor. These motors are linked to one fuel tank, i simply turn a 3-way valve to run each motor. The question is, i am running Mercury quickleen in my tank (1 oz per 10 gals) will running quickleen through my Yamaha T8 4-sroke be harmful?
Thanks
Mike
