Ok Guys,

Since I need to change out the props with new I am making sure they are correct ones for the boat.

I am trying to figure out what prop size I should have? I currently have A2's but with the information I can find it doesn't seem correct. Other posts show A4's maybe even A5's.

23 Fishmachine
AQD40A 135hp
280DP 1.95 gear ratio verified by removing the top cover of the out drive and rotating the prop one full turn while counting the upper shaft rotations.

The boat seems to run fine but I don't know for sure if the previous owner Moo Fish didn't change anything.
