So I hooked up my 200 hp yamaha ox66 and my T8 yamaha to the same fule tank. I ran the fule line into a water sep fule filtter then into individual primer balls then to the motors. I took it out for a small run the other day, ran the kicker for a bit then ran in. All was well then today I went fishing and ran the kicker for 6hrs ran great. Fired the main it ran well up on plane then started to sputter I backed it off and the ball was soft but it was runing smooth. So back to speed and the same thing started to sputter.... Any ideas what's up any help would be great.
