Bob, Any slop in the steering system can set up all kinds of noise and shakes and can sound and feel like some else and some place else. In other words, slop is bad. prop hub to strut should be i to 1/2 tines the shaft dia. In other words the clearance along the shaft between strut and prop hub should be 1.5 to 2.25". There again the less clearance is better, less wip.

Cuped wheels. I may be wrong on this, but here goes. Cuped wheels are usely used on higer speed boats. They seem to give better out of the hole speed as the engine can come up to rpm faster and as boat speed/engine rpm get up the cup gives the effect of appox. 2" of pitch.
