Hello all. I have removed and reinstalled my 3.0 mercruiser due to broken starter bolts. I was under the assumption that as long as it was out and in, nothing would change and would not have to align motor. I have looked into assembly and spines look perfect. Equal amounts showing all the way round. I would like to put the outdrive on today, to be able to use it for the fourth, just want to ask you fine folks basically how much would the alignment have to be off to cause problems. like I said, visually it is perfect and it was out and in. I changed nothing. But still, would like to be sure. Thank you for any help.
