Re: "David.... In addition to Jon&
To be clear, my trim setting is untouched since I bought the boat 2 months ago & I guess it is not at its full limit, rather its 2 notches away, nearly full to port.
Heres the pic:
"...to compensate for the pulling action, move the trim tab in the direction of the pulling a little at a time...
Joereeves, what you say does seem counter intuitive, though I guess I hadn't really considered all of the forces at play... & now I think I understand why you're right.
I have some experience in aviation & what you say would counter traditional "trim" wisdom on an airplane. Lets say a jet or a twin engine airplane is out of trim and yawing to the left, you move the rudder trim surface the right to counteract that yaw. Single engines airplanes do suffer from torque steer too, though I hadn't considered my problem from that perspective before now.
So, I guess we need to move the trim tab in same the direction as the torque steer because that creates a larger surface area for the propwash to act against to correct the torque steer, thereby pushing the motor in the opposite direction. Interesting...
Again, I haven't touched my trim tab, because I had assumed correcting a turn to starboard required trim adjust to port & my tab is already -mostly- to port. Just like joereeves said.
Someone needs to do a 3d fluid flow simulation & post to youtube so people can better understand this phenomenon. There isn't much info out there on how this really works. Just lots of info saying "here's your trim tab, adjust it to correct torque steer", offering no further guidance.
Before I throw down on a hydraulic or NFB kit, I will start by adjusting my trim tab about half the distance to full starboard from its current position & will report back next time I splash the boat.
Thanks for the help in getting my head wrapped around this issue!
