new motor mounts Yanmar ysb 8

so i have new mounts installed, not a bad job. lined the shaft up with tranny plate. don't know if i was just lucky but after 30 minutes of small adjustments to new mounts just slipped into place. 5" disc, so 1/1000 per " to gap the 2 plates and it just seems to fit. Now here's the question, all seems to work well, fits good, I can now turn the prop shaft by hand behind the tranny, outside just 2 fingers to turn the prop. Could not do this before, does this sound right to someone who knows what they are doing? also, when i installed the new mounts, i measured the bolts length to the old ones and the motor ended up 1/2 inch higher, i am assuming because the rubber doesn't crush like the old ones (prob 30 years old). so question is, have i forgotten anything or is there something else i should be checking?

Re: new motor mounts Yanmar ysb 8

Well I just did mine yesterday and my install sure sounds like it went just like yours.
Mine was sagged out and while I did not check alignment before I changed them, I set the nuts to the same height of the old just as you did and when I went checked alignment, I didn't have to do anything, it was inline.
Spinning freely is I believe a good thing.
