......... I never could get it to work right when it was pinned straight. There was a little play even when pinned. If there was anything that gave resistance on 1 side or the other, the PA would track to that side and sometimes it would only go straight if I turned all the way to the opposite side. I tried for weeks with that and didn't like it. Found it had to be perfectly straight and perfectly inline with the rudder.
Also, it would be slow in turning unless you were up to speed and wide turns only under power. As Oldtimer said, you had to slow the motor or stop it to turn.
Also as Oldimer said, it will turn on a dime when not pegged and using the rudder and the engine to turn even at slow speed .......... but you have to be careful at high speed so it doesn't throw you a little. It's that good !!!!! ......... it also makes it adjustable if you are weight challenged like me and shift your weight or have some drag somewhere. Also makes it easier to hold on a piling when fishing in a moving tide.
That's just my take ........... but again ....... it's personal preference .... I like it working w/the rudder and Oldtime likes it pegged ........ thing is that it can be changed by just pulling 1 pin.
