The Volvo Penta Duoprop 21924264 J4 SET - its performance, durability, and comfort have all been prioritized during the design process. The J series is comprised of a high-strength aluminum alloy with four layers of corrosion protective paint. Innovative blade design and huge active propeller diameter ensure ideal performance and fuel efficiency, as well as smooth running, great grip, and maneuverability. The front propeller has three blades, and the back propeller has four blades.

Key Features:

• Blade geometry is patented, and the active propeller diameter is huge.

• Aluminum alloy with high strength and durability.

• Anti-corrosion properties are outstanding.

• The front propeller has three blades, and the back propeller has four blades.

• Ideal replacement for type A and type B propellers.

Note: In engines with more than 240 horsepower or capable of speeds more than 38 knots, always utilize type C stainless steel propellers (45 mph).

• A Series numbering is almost equivalent to J-Series numbering, i.e. A5 = J5.

• B Series numbering (approximately) correlates to one size larger J-Series numbering, e.g. B5 = J6.

• The same propeller cone, propeller nuts, and washers are used as in the A and B series.

Note: On the same drive, do not mix J-Series with the A or B series. Only utilize the same propeller type on both drives for twin applications.
