Im finally getting around to fine tuning my 818.

I just checked prop to pad I was at 4 1/8. I boat had a little walk and felt that I had a little speed to gain.
I have a manual jack plate. The bolts were tightened so that I needed a short breaker bar to get them loose. I set prop to pad at 3 1/2 inches.
Im hoping thats in the ball park.

Just wonder were everyone is getting the best performance.
