I have 1988 Mercury 25 HP s/n# 0B267454<br />Steer with tiller.<br /><br />Where do I tighten the pivot shaft? It is very loose and the motor wants to torque to one side at full throttle. If I could tighten the shaft, it would put less strain on my arm. I have adjusted the trim tab, helps a little.<br /><br />thanks in advance.
