I've been noticing my tunnel leans to the left when running on plane and the faster I go the worse it gets. Thought it was due to my battery being on my port side but my partner rode in it for the first time yesterday and said it was from prop torque. I didn't think so until I tested a new prop yesterday, it was leaning worse at top end than with the other prop. The new prop was stainless and had more bite and better lift.
Is this just related to tunnel hulls or aluminum boats in general. I'm going to switch my battery to the starboard side to see if it helps any.
