A friend's boat steers had to starboard and easy to port. I am suggesting a small trim tab on the rudder port side trailing edge. Sound right? top or bottom with a RH prop?
Thanks
When I had cable steering that's what I was going to do.
However a quicker easier solution MAY be to attach a spring or rubber band to the rudder horn until the boat goes straight. Haven't actually tried that though.
Brooksie I did answer your post on the fuel manifold.
