I would say a 14.25x19 Stainless.

I have several props from my old 150 evinrude. Both stainless, 15x17 & 14.5x19.
I am currently running a 14.5x19 with my new 150 johnson. I'm getting 4,600+/- at WOT.

George, if your only getting 4,600 rpms with a 14.25 x 19 prop, you are "WAAAAAAY" over proped.
That engine wants 5,600 rpms.
Your going to kill that engine much faster then it would die, if it had less prop.
What size boat is the engine on ?

George....you sure the tach is correct. That thing should be doing about 1000 more rpm's. My bud runs a 19" on his 17(49mph) outrage so I assume that would be perfect on an 18.
