Which way do I turn it I need a starting point.You can adjust the trim tab just above the prop. It may help some. If the boats pulls right turn it to compensate to the right. A little at a time to test how much to adjust.
Think of it like a rudder. With the motor down and your head above the prop turn the tab so the face of it turns right. From the to it would be clockwise.
Turn it in the direction the boat is turning. The force of the water rushing past it will want to turn the engine in the opposite direction. What size engine and type of steering do you have?
