Guys, I've got a cmb 90 gold head in a 42 inch cat that I bought recently. I'm looking for props to try. It came with a 646 octura and a 270 Prather. Are these good to start with? Any suggestions will be appreciated...
 
I pitted for John harter way back same cat but had a Simpson 90 and he ran a Prather 270 I run a Prather 265 on my F,s subsurface .
 
Thanks Brian , I've got a 270 think I'll try it first and go from there and I just put a new pipe on it from stumpfab. Also welcome to I/W. APPRECIATE THE HELP.....

cheesh,,some of these props are small.
ur saying a .90 right? a .67 spins a p265 or oct 465 easy.
in any case to make it "work" a 1667 or a 467 with some cup if the 1667 is too much lift/trouble. might have to bring the strut/prop hub just a fraction of an inch out the water
