The pictures don't really show it too well but is the sequence reduction gear/intermediate shaft with bearing/shaft coupling?

If so then how is the alignment between the intermediate shaft and the prop shaft? Is all the misalignment in the intermediate to gearbox? Is the misalignment duplicated in the gearbox to intermediate shaft?

You really have to start at the prop shaft coupling and work forward, but If there was an issue with the strut mounting previously, you should loosen the strut and see if it is the source of the misalignment. I had a boat recently (40m glass production boat) that was delivered with a misalignment in the struts that required cutting them and removing 1.5 inches and rewelding to obtain correct alignment so anything is possible at that end.

If this is a wood boat on the hard is it blocked properly?
