60 degree timing cover

[mkwns]

Guys, I have to change a cracked flywheel cover on my boat that is on the water. I'm worried about not changing the timing. I don't have the boat close to look at but I'm thinking I can remove timing wheel and tab, linkage. And put everything back he same position. Anyone do this before? I changed starter drive gears years ago and had to remove cover. I don't remember any problems and it was at home so less stress if it didn't start. Any help appreciated.

Went down to marina early by 6am. finished with no issues and at gas dock by 7:30. So it can be done.
