R25 Classic Prop Specs

[Kmiller]

I just recently got a 2008 25 Classic. Of course I have been learning fast with some fuel issues (algae in the tank) and other things. I have caused a minor ripple on my prop. I am looking to see if anyone has the specs for the equivalent prop. I’ve talked to the factory and they don’t have the records that far back so if anyone can give me the specs of theirs or has anyone re-propped it for additional power or speed? I’m looking to buy a backup and have the original refinished. Any recommendations welcome.

17x15 3blade .105 cup

Cummins Engine 130 Hp
Acme part # 1386
17x14 3blade .105 cup

Yanmar 110 hp
Acme part # 1118
17x17 3 blade .125 cup

Yanmar 40 hp
Acme part# 542
13Rx11.5 3 blade .080 cup

Yanmar 30 hp

For the 150 HP Yanmar 4BY-2 the Acme prop is a 3 blade 17X14 with .105 cup. Sorry, don’t have the part number.
