Boat is CD25, twin BF90A hondas. Seem to run well.
WOT is 5100-5200 or so.
Top speed is just under 30mph or so.
It seems that there is some range in RPM to move up in max speed.
For anyone with twin 90s, what props are you using?
My preferred cruising RPM is around 4000-4200 with about 18-20mph.
Currently have:
13.25 inch diameter by 17 |

Call Ken from Prop Gods. He's knows his stuff and will tell you quickly what you need based on a variety of factors. He helped me with repropping my 25 after I bought it.

I had twin Honda 90s (circa 2013). OK, not on a 25' CD - a 26' Venture.
I got about 39 mph w/13 x 15 inch aluminum props WOT @ 4800 rpm.
I cruised about 3200 rpm, 20 mph or so.
Hole shot was like a jack rabbit.
It made me smile.
Aye.
