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.

Subject: Stus-List A4 Engine alignment

 

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
