I have not proceeded yet. Perhaps tomorrow evening I will give it a try. I am glad you added about lining up the holes. Trying to get the best alignment with the rule at the start will be a good idea. Thanks much.
The gear is now installed on the propeller shaft. I was able to make some adjustment as the gear was nearing the hole alignment. The pin is in, and all seems good. The water pump is assembled and needs installed back on the lower unit. Thank-you for all the help.
