I troll Lake Michigan with one motor at a time.I know the Yamaha manual says to raise the other motor,but when I do the steering binds up, and last time out I noticed a little oil running down the helm behind the steering wheel.My question is,do I really need to tilt the motor not in use? is there a chance of a following wave finding it's way up my motor? Putting extra stress on the steering worries me.Any thoughts on this? Thanks, Joe.
