I have a 1972 Grew 195XL with 165hp chevy inline six. I finaly got it on the water this week and the steering is having problems. The steering works fine at idle but as soon as I give it some power it becomes very hard to steer to port. I have lubricated the entire system and it seems a little better. If I adjust the rudder that the exaust goes through, on the lower gearcase, will that help? I have read that it could also be an issue with torque from the prop.
