So I’m getting ready to do some maintenance on my motor (2006 Yamaha 150 TXR) and noticed that the trim tab above the prop is completely loose. I tried tightening the bolt, but seems like it’s corroded out so that it won’t tighten all the way anymore.
I plan on replacing the trim tab anode when I do my water pump, but whats the best way to set it back to the correct position? I know the general idea is to counteract the sideways thrust of the prop - do I just take the boat out and see if pulls to one side and adjust the angle of the tab based on that? or is there a more accurate way that doesn’t rely on “feel” to make sure the boat is actually tracking straight in the water?
just out of curiosity, what is the relative importance of setting this thing correctly? Does it really make a noticeable difference?
Thanks!
