Brand new cutlass bearing and shaft. When I put the dial indicator on the shaft
it was moving about .015 out of true, Upon screwing around with the motor
mounts I got that reduced to .005 approx. Now this was with the coupler tight
to the tranny flange. So, I then disconnected the coupler and adjusted a little
more but I had no feeler guage with me... I asked the yard mechanic to have a
look at it. With all the mount adjusting bolts free and easy to move and the
lags on the feel loose I was hoping someone with more experience with this sort
of thing could do it quickly... However, there is the chance they won't get to
it... They didn't seem all that thrilled about doing it. He did say if I was
to break all the bolts free it would save me a lot of money...

Dumb questions:
1. Is the cutlass bearing good?2. If the motor is out of alignment can you see
the shaft wobbling while in gear? Joel

Put another fixed prop on and see what you get.
It may be the prop doing it.

Well,
I have a brand new shaft and had the machine shop check the prop hub on the
lathe. �they said "you can't get any better than that"
�
I can hear and feel the blades opening and closing as I rotate the shaft by
hand so nothing is stuck.
�
I guess it is just a pain in the butt, time consuming, task...
�
I'll have to get the feeler�gauges�out and keep messing with it...

Danny. The engine has to be adjusted on its mounts so that the coupling faces
are as parallel and in line as you can get them. To start, remove the
connecting bolts completely from the coupling flanges. Check that the flanges
are tight on the shafts and the lock bolts are wired properly. Check that the
shaft is in its best centered resting position and that the engine is as close
as possible to being in line. Then put the bolts back in loose and, using
feeler gauges inserted between the coupling faces, adjust the motor position so
the faces meet exactly with the same clearance measured around the face of the
couplings. Then tighten the engine mount nuts and re-measure the flange face
clearances. Once you are satisfied that you have the engine in the correct
position, tighten the flange connecting bolts.

If you still have problems after completing the alignment, check that you do
not have a propeller problem.

Hello all,
�
Well i got out for a sea trial on Sunday. �The engine runs nicely but,
it vibrated like crazy underway. �It appears I did not align the engine.
�I've gotten it better aligned now but, are there any tips or techniques
to adjusting this thing to get dead nuts aligned?
�
It seems a very tedious�endeavor... �When I put a dial indicator
on the shaft, just aft of the coupler, I can't seem to get it better than .005
of an inch. �It started�out�at about .015 when i first put
it on and i thought that the .005 may have been acceptable but, it still
vibrated.
�
I've asked the yard mechanic to have a look and align it for me.
�However, if he doesn't get to it this week I'd like to get it done
myself before the weekend so that I can FINALLY go sailing!
�
Thanks,
Danny
