I am currently running a yamaha 70 hp on a 15' striper turning 5800 and 6000 rpm fully and I mean fully trimmed.
The prop I am using is a stock aluminum prop 13.25 x 17.
What can I expect the performance difference to be by canging to a 13 x 19 stainless prop. Speed and rpm change?

Also I am usually carrying 1 other person, 6 gal. of gas, and 2 batteries. The estimated weight is 1275 lbs. This is boat, motor and contents.

The Yamaha 70 on my 15' Super Sport is turning a 13 x 19 inch aluminum Yamaha propeller. When trimmed out I am seeing 6000 rpm on my Teleflex tachometer at WOT running at about 43 mph. This is with one person and one full tank of gas. The boat is bottom painted.
