250ex Twin Engine Prop Size needed

[250ex]

Hi all,

Need to replace the props on my 250 ex w/ twin 115hp Yammies. The current prop size says 19m and I am looking to get a SS propeller. Any suggestions?

I like the stainless steel 4 blade props. They keep you on plane at a lower speed and that results in better fuel economy.
My twin 150hp's came with a 19 pitch which was way too high for the boat weight of my 250ex and could barely reach 5000 rpm on rare occasions. A 17 pitch 4-blade was a big improvement, but the 15" is dialed in for my purposes.
I wouldn't go any smaller than 15 if you use a 4 blade.
