I replaced some on mine a few years back. I do not recall a plus and minus and assumed that it did not matter as it is a breaker on the positive side and only running current through it.

I have an LS2000 2001. I have replaced oil lines and filter, removed one engine and performed top end rebuild, change drive bearing and seal, replaced drive shaft, replaced impellers, and rebuilt the pump bearings so far. So if you have questions, I may have answers. Happy to help.

I removed the oil pumps on each motor, replaced the lines and filter, opened the bleeder at the top of the pump and allowed it to flow until all bubbles were gone and then closed the bleeder. You are correct that you can turn the motor over with either the fuse or the safety lanyard removed to get oil thru the remainder of the lines. Or you can run the motor but dribble oil into the carbs with the oil pump cable opened to full for max oil flow. I also mixed oil between 100:1 and 50:1 in the tank to make sure that I could run the motor until all bubbles are out of the lines.
