I understand that the purpose of the trim tab anode found on most sterndrives and outboards is, along with combatting corrosion, to offset torque generated by the turning prop. This was very evident on my fathers boat when he first bought it; the tab on the Yamaha 140 was set straight and the manual steering was dog- heavy in one direction and fingertip light in the other to the point where if you let the wheel go the steering would creep around on its own!
My boat, on the other hand has power steering on the Mercruiser so there is no feedback felt through the steering. When I bought the boat the tab was set full over to the right, which I can only assume the previous owner did as a guesstimate to unload assumed force acting against the hydraulics steering system?
What is the best way of determining where to set this tab? Is tab angle going to have any effect on how the boat handles or rides? Is the any issue with setting the tab straight to minimize drag and keeping the steering loaded?
Cheers
