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

<![endif]--><![endif]-->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
