I changed the water pump on my 2004 Suzuki DF70 4stk. She wouldnt pee. I then tried a plastic water filled bucket to cover intake. Wouldnt pee. I slowly shifted to forward, & prop kicked. Now she still doesnt pee, AND I can shift to neutral, forwd but not reverse. Prop moves freely in neutral, but turns w hesitation in forward. Doesnt turn in reverse. Did i mess up the shifter somehow?The engine runs smooth otherwise.
