Thanks for the help

The gravity 3 just means 3 bags. Doesn't tell me whether they are reversible, but it a good chance if you have a 2011. Do you have the sprinkler valves above your v-drive that has a single aerator pump connected to that? Then you would also have 3 separate emptying aerator pumps if you have the older aerator setup.

Otherwise you will have 3 reversible pumps all mounted together on the transom.

As for the prop I couldn't find details on an OJ 511. The differences between the 1433 and the 1617 I indicated before in the parenthesies. The 1617 is a 1.5" lower pitch prop, so you lose some top in but it will pull like a tractor.
Lower the pitch = more pulling power. Like the lower gears in your car or truck.
