Repowering 23DVCC with Twin 150AT Suzuki need prop size help

[Black Sheep]

Any ideas on good prop size for 2000 23DVCC? Repowering with 2 x 150 Suzuki engines. Boat has twin 150 yamaha 2 strokes now with 3 blade props. Thanks in advance for the help.

Interesting. I don’t see many 23’s with twins on them. Cool boat.

I'm really not sure on This one. The DF150's are Inline 4 cylinder engines. The Suzzy's are ALL geared lower than all other manufactures. I would "Think" ?

3 X 15 X 20's

You'll need the data from the current set up and like Wart mentioned the final drive ratios will be needed to get a starting point.
Seems like a few sea trials will be needed to pinpoint this one.
Those 150's smokers look too purty to let go. (can i have them?)

Interesting setup. I'd think the weight increase with two screws is not ideal considering this boat is so ass heavy. Most of us with these boats work overtime to move weight fwd. Batteries etc... I'm sure you've thought about all of this tho...

Starting point would be 3X 15 X 20..... R&L
