44 Swift trawler prop specs

Hi All I have owned my boat for about 6 months and now I would like to dial in my boats performance by adjusting my prop specs. I am reaching 3490 -3500 on my port motor and 3530 on my starboard motor. Full fuel and full water plus all the stuff my wife has loaded the boat with. LOL. With a light fuel and water load I am seeing full RPM 3540 and 3560. Can anyone provide what propeller specs that you have and performance data you are seeing.Thanks

I get 3650 light load and 3550-3590 under heavier loads. Sea conditions can impact too (strong winds/currents).

Best to use a place that will computer scan the props before AND after any work is done and give you both printouts.

Let us know if you find the specific specs. If you cant find them I can try to dig out my last computer scan. You always want to have both props done at the same time and matched to one another.

There are all sorts of pros and cons to adjusting propellers in certain directions. Really depends on your application, intended use, etc. Some may opt to have props adjusted for better slow cruising/fuel efficiency while others may want higher cruising speeds.

Mystery .Thanks my main goal is to reduce engine load and add longevity and less wear on the motors. I purchased a brand new set of props from the previous owner. Before I install them on the boat I was hoping to see what other owners have installed on their boats with real world rpm numbers. You appear to have your props specked out properly. It would be Greatly appreciated if you can share your prop scan data that I can apply to my new set of props.Thank you for all your advice. Steve
