You've got to call AB Marine to find out what blades will work with the Yanmar. The change in engine torque and gearing will require something slightly different that you don't have on on the current Westerbeke based blades.

Catalina 400 Autoprop
I am repowering my Catalina 400 Mark I (Westerbeke) with a Yanmar 4JH4A (the engine presently being installed in the 400 Mark II). My present Autoprop will need new blades to match the higher Hp and torque of the Yanmar. Any suggestions/experience on which ones to use with this engine? Thanks!
