You could have a custom prop made or you could have the pitch altered on the one you already have.
I have a 3 blade Yamaha prop. Like I said the boat really likes the Larger prop 161/2 with 19 pitch
I like the low end and mid range of the prop the puts out but when I have a clean bottom
the boat wants to over rev to about 6200 rpm wide open throttle and 54 mph. I would love to lower the rpm down 5900 or 6000 at full throttle and pick up a few more mph of top speed.
Who are the best prop guys to build a custom prop for the f350 ? Is it unreasonable to be able to get 57 or 58 mph out of this set up ? Thanks for your help
