Poor Skippy!!! It sounds like your amateur attempt at alignment is doomed
to failure.

Why?

Because there is a lot more to alignment that just centering the shaft in
the log. A perfectly centered shaft can fail to be perfectly aligned with
the transmission output shaft/flange.

IOW, if the two flanges that bolt together are not perfectly parallel both
top to bottom and side to side and everywhere else, when the propeller
shaft is centered in the log there will be a terrible vibration set up as
the two flanges will bind and loosen as they rotate. The only way to get
them perfect is by using two dial gauges, one for each flange and as you
rotate them with perhaps an 18th inch of space between them (in neutral)
by hand both gauges must not move more than a blonde hair.

Sounds to me you are doing the job only halfway, Skippy.

Heh. Reading deficit, eh?

We got the shaft centered. That took care of the alignment with the
cutlass. The shaft turns readily, by hand, from the skinny end outside, the
middle, next to the log, and the transmission, where I've got the coupling
mated with the bolts, but not yet tightened, as we've not yet aligned the
engine.

That's what I'm talking about. When you snug up the two flanges (propeller
shaft flange and engine/transmission flange - assuming engine and transmission
are integreal) unless their two flange faces are perfectly alligned snugging
them down together will result is binding and releasing (vibration). Prior to
snugging them down face-to-face you must assure yourself that they are
perfectly parallel both horizontally and vertically. And, keep in mind,
depending upon the flexibility of your old hull, that the relationship may
well change when the boat is back in the water (not that that's EVER going to
happen, LOL!)

It can be rather tricky. Some of the Irwin 43's I helped build working as an
MEP (mechanical, electrical, plumbing) experienced this problem as the hulls
were rather 'flexible' and the alignment was done on the production line. Some
needed to be re-done once splashed.

Hey STUPID! Read the message before you set out to amaze us with your
knowledge (or lack thereof). The O.P. stated, "... but not yet
tightened, as we've not yet aligned the engine."

Read it again, "WE'VE NOT YET ALIGNED THE ENGINE".

Got it yet? HE HASN'T YET ALIGNED THE ENGINE, you ignorant fool.

Question. Does sweeping the floor and emptying the trash can
constitute "help build"?

Duh, aligning the engine is a necessary part of the process. Because Skippy
has yet to do so does not mean that in order to align engine with propeller
shaft that he will never be doing so. He has even described how difficult the
engine bed alignment bolts were to reach and how he didn't have a wrench that
fits well. That means Skippy is 'in the process' of aligning the engine in
order to align the two shafts.

Got it yet? HE HASN'T YET ALIGNED THE ENGINE, you ignorant fool.

So you must be thinking that Skippy intends to never align the engine with the
propeller shaft so both shafts will be on the same centerline when looked at
both horizontally and vertically? How droll!

Question. Does sweeping the floor and emptying the trash can
constitute "help build"?

Yes, it does. Irwin hired several women whose job it was to clean up the
interior and exterior of the yachts while they were being built. The
carpenters, for example, would never DREAM of cleaning up their sawdust.

But, I was not a janitor. Now it is my turn to ask you, "CAN YOU READ?" as I
plainly stated I worked as an MEP. This means I installed systems that
included Mechanical (such as Yanmar engines) and air conditioners, sinks etc.,
Electrical, such as wiring, lighting, electric pumps, generators, distribution
panels, etc.) and Plumbing such as pressure water systems, waste systems, fuel
systems, etc.

Of course these things you never do sitting for 25 years at the Bangkok dock.
LOL!

Janitor? No one argues that you ever attained this lofty position.
Goodness, being a janitor involves washing things and Dirty Willie has
never bragged about that (and it is sure that if he ever had, be would
have bragged about it).

NO, according to other posters Dirty Willie's highest skill attainment
consisted of reading a water meter.
