Great post Eric.
The pictures show the shaft seal and saftey collar close to the two flanges that bolt together. In mine there is a lot more space between them. I would say I have at least a foot of drive shaft from the flange to the safety collar. Is this right?

9 out of ten times you have to raise the engine because it settles over time, in my case I knew I would be a touch high with the engine because of the glass that i added to the tops of the stringers. It pretty much is common sense, Ive spent entire days trying to get some boats to align and then again Ive spent 30 minutes. most of the time i will mess with the rears to get alignment if i find i cant get it to align then I'll start messing with the fronts. v-drive boats are much more critical on the alignments because of the shorter shafts and you can definitly tell when a v-drive transmission was out of alignment because of the wear to the output coupling, it will try to act like a u-joint and will wear the splines and create all types of problems. on inlines if out of alignment it has a tendency to wear the case because now your putting side load on the planetary and worse case it blows all the gears on the planetary and the list price on a Borg Warner planetary is around $1100.00, better off buying a new transmission, also that excessive load will eat horsepower and will also cause the trans to run hotter than normal.

Eric, do left-to-right adjustments always involve the rear mounts or when do the front mounts come into play (besides the whole engine being off left or right and the faces not even meeting parallel, obviously). What about up and down adjustments? It seems like you could either lower the front, or raise the rear? How do you make the call?
Edit: the more I think about this, it probably comes down to common sense, but I'm just curious as to your strategy or starting point when it comes to working the 4 mounts when you tackle an alignment issue. This write up is great, by the way.

Eric, all that boat needs now is a set of polished Hi-Teks to complete the resto.
Good how to on the subject,I know and you know but thanks for sharing your vast knowledge of this critical procedure.
Is that a PCM tranny, and the same as you are building for me?..........boat dr

This is the finished product, the coupling spins as easy as if it was not connected to the prop shaft, this means you are not creating any loads in the driveline which with mis alignment you create hevy loads and major damage.
One thing to mention is with the bolts out of the 2 couplings and with the gap i had, if you spin the shaft and the gap stays in the same spot then you have mis-alignment, if the gap turns with the shaft, then you have a bent shaft

this mount has the adjustment for up and down, the front and back mounts have this adjustment to adjust accordingly, I had to drop my back adjustments a touch to close the .004 gap at the top, remember i added glass to the top of the stringers raising the engine a touch.

This is a pinch or clamp tight bolt which controls your side to side engine movement, i loosened both sides and kicked the engine to the left to close my gap on the right, I adjusted until i had .000

If you look very close you can see a slight gap on the right side and this would be your first location to stick the feeler gauge, you can start side to side or up and down, I started side to side and measured .010 at the gap. my up and down was .004 a the top
