engine alignment

[legmaker]

Any one know haw to align a motor?

I helped a friend with a bent drive shaft and then after finally getting the collar off the engine end, we talked with SECC and they said the engine would need to be aligned, so off to the boat yard it went.

Also any ideas on an easy way to get the collar off and the new drive shaft in?

Just curious for future knowlege.

If you don't change out the strut, you shouldn't have to change the engine alignment.

To remove shaft:
First off you need to remove all the two or three set screws on the coupler. You'll also have to loosen the stainless collar that is just below the coupler, it'll get left behind when you pull the shaft so, you'll have to remember to slide it back on when you put the shaft back on. It's a safety collar which prevents the shaft from sliding down and hitting the rudder if it were to fall out of the coupler.
Then you'll have to loosen the shaft strut so, that you'll have room to get the shaft out past the rudder. Now for the speciality tool. You'll have to get a slide hammer threaded onto the end of the shaft and basically drive the shaft out.

Reinstallation:
Basically the same in reverse order. Remember the safety collar and sikaflex the bottom of the shaft strut.

Alignment:
put the shaft into the coupler and cinch down. Push the coupler into the output coupler of the tranny but, don't put any of the bolts through. Then with a feeler guage measure the gap around the coupler to ensure that there isn't anywhere around the coupler where the guage catches. If so, you'll have to loosen the engine mounts and lift or lower the opposite side where the feeler guage catches. There shouldn't be more than about .002 difference around the coupler.
Once set, tighen the engine mount bolts and you should be set to go.

Final check is to spin the prop shaft within the strut to make sure it's smooth around a full revolution.

V-Drives are a whole different story. Haven't done one and don't want to.

WOW!!!!!!

I guess if I ever need to do this it is off to the boat yard.
