23 seacraft cuddy with 135 opti's

[seaherby1]

I have a 23 cuddy with a bracket and twin 135 optimax
on it.
I wondered if anyone can tell me the prop size I need and the expected gph and cruise speed. Thanks, I can't wait to get it finished and on the water

I BOUGHT A PAIR OF USED 135 OPTIS TO PUT ON A 23 SCEPTRE WITH A BRACKET. I HAVNT INSTALLED THEM YET. THEY CAME WITH 21" 3 BLADES I DONT REMEMBER WITCH MODEL. THEY WERE ON A 23 CAPE HORN. I WOULD BE VERY INTERESTED IN ANY INFO YOU LEARN SINCE IM GOING TO BE RUNNING THE SAME SET UP.

Just a guess but 19's or 17's, consider the loads will be NORMALLY carrying. Both sizes should be easy to try even in alum. which will get you close.
