| Motor adjustment made little difference in hole shot, top speed, steering torque, or tendency to suck air with the SS prop. Still very easy to turn left and difficult to turn right. Adjustment was relatively easy to do with the instructions that you provided so I had little to loose in trying this before spending $$ to tune the prop.
I did consult my manual and found out that I adjusted the trim tab the wrong way when attempting to eliminate the torque issue. You move it to the direction that the boat wants to turn to make corrections. I did the opposite thinking I needed to oppose the direction that I was fighting it. Not sure I understand why it works that way but will give the SS blade another whirl with this trim tab setting and see how it goes at the lower transom setting.
I did try the original aluminum prop at the lower transom setting and it trimmed up fine without torque. Very little difference compared to what I was used to in the middle hole. Speed was about 1 mph slower than SS. Hole shot and top rpm were about the same.
For whatever reason it did seem a little easier to suck air with the aluminum prop so I cleaned up the shaft and propeller splines, and torqued 1 flat tighter than I had done previously. Noticed a little bit of galling / pitting on the tapered portion of the splined shaft and the mating surface on the stopper (which I had not previously removed). Suspect I had a little bit of play here causing this.
