finding the right prop

[junior11]

My hull is a 1972. It was rebuilt and is pretty heavy. I had about 100 gallons of fuel on board. I think that newer hull is probably a lot lighter than this. Those optis are supposed to be pretty good on fuel. Also I have a t top and an eisenglass front window which I think catches a lot of drag.


Another thing is that I am pretty sure I am getting some cavitation from my transducer. It's a transom mount mounted too low and in the middle since their used to be twins. Time will tell.
