Re: Prop Shaft Offset
"As I understand it, the offset is an attempt to address prop walk by changing the angle at which thrust occurs."
Jimgo, you make good points,..but as for the offset, FYI the principal reason for it on the P323 is not for the propwalk, but the fact that that the rudder is mounted on a skeg. Most boats with skeg-mounted designs have the propshaft offset, otherwise you could not remove the shaft! Reducing propwalk is a side-benefit, not the objective.
I am guessing he will have a talk with the yard which did the repower. I don't know what can be done - and how running an engine mainly in reverse effects the warranty!
This is a weird one.
