Engine alignment... Best way to do it??
I just reinstalled both engines in my Sonic. The motor mounts were never moved, but the transom assemblies were removed, resealed & reinstalled.... now the alignment is off. What is the best way to determine how to adjust the engines (which way to go)?? This is the third set of engines in the boat but the 1st time the alignment was off.
Adjusting this when there is no one to assist makes it difficult a best.
Ideas????

Probably the first time the transom assemblies where removed. Do you have offshore mounts?
It dosen't take much to throw it off. I have a tool I use first that goes into the coupler to see if its high or low going thru the gimble bearing. It drove me crazy trying to use an alignment tool because you can not see. As soon as I eye it, then I use the alignment tool.

The engine may not need to be moved, alot of times, the ball in the center of the gimbal bearing is just slightly off. That will prevent you from getting proper alignment. Even gets worse if you have extension boxes.

I use a 1" dowel. Went to Home Depot with calipers to ensure it is exactly 1". Insert dowel in coupler and adjust eng. until dowel is centered in gimbel bearing, almost like a gun sight. When this is accomplished use the align. tool to finish. Found this method to be the easiest.

Good idea on the dowel... I can use that. But what is this about the "ball" in the gimbal bearing being off slightly??? How to check that??? & fix??

The check is using the alignment tool. If it doesnt go in all the way, try to mess around with the ball a bit. What I have done in the past, is pull the alignmemt tool out of the coupler, leave it in the gimbal bearing ball, then knock the outer end of the tool with my hand up , down or side ways until the tool slides all the way in, smoothly.
