Propeller

Can anyone tell me the specifications for a propeller for an R25 (2009) with the Yanmar 4BY2 150 hp engine and KMH40A gear. I believe the prop for a 150hp Cummins is a 17 x 15, 3 blade, .105 cup Acme #1384. Maybe it's the same for the 150hp Yanmar?

Am shopping the internet for a low price on preowned props as a spare and this information would help. Also, curious as to model # for a prop zinc for the Yanmar 150hp.

The prop we currently use on the new boats is a 17X14 with .105 cup. We did use the 17X15 on the earlier model Cummins.

Andrew, is there any advantage to switching my Cummins to the flatter prop? The thought being to have a spare prop by installing the new one and keeping the original for back up...

Ah.... Frank of Ainokea reminded me to look under technical specs where Andrew, or course, has posted prop specs for the boats: viewtopic.php?f=7&t=36 . But, it doesn't include the newer (i.e., ≥125hp) Yanmar engines. Still its handy for the older boats. I would suggest updating this resource.
