BS PRO Duo Prop B4 Aluminum Propeller Set for Volvo Penta 280/290DP Stern-drives.
Equivalent to Volvo Penta Duoprop Propeller B4 Set # 854817
BaekSan Duoprops are intended as direct OEM replacements for the Volvo Duoprop Propellers, and as such, use OEM equivalent geometries.
For all engines with speeds in excess of 35 knots, the stainless steel Type C propeller should be used.
Aluminum Duoprop propellers for gasoline powered engines. The two 3-blade propellers have very thin blade profiles, demanding the highest level of precision.
Note! Do not mix Type A, B and J propellers. Always use propellers of the same type and size on the drive (or on both drives in twin installations).
