Installation Notes

  1. The Type J series propellers are designed as a direct replacement for both Type A and Type B series propellers.
  2. When replacing a Type A propeller, the series numbering corresponds approximately (e.g., A5 ≈ J5).
  3. When replacing a Type B propeller, select one size larger in the J-Series (e.g., B5 ≈ J6).
  4. Never mix propeller types (A, B, or J) on a single drive assembly. Always install as a matching set.
  5. For vessels with twin drive installations, always use propellers of the same type and size on both drives to ensure proper boat handling and performance.
  6. For engines exceeding 240 HP or capable of speeds above 38 knots (45 mph), you must use Type C stainless steel propellers for safety and durability.

Troubleshooting & FAQ

How do I know if this J-10 propeller set is the right replacement?

This J-10 set replaces the Volvo Penta OEM part 21924270 and older Type A10 sets (854773). It is designed for 280, 290, and DP series drives on gasoline engines up to 240 HP. Confirm your drive type and engine output before purchasing.

What are the benefits of Type J propellers over the older Type A and B?

Type J propellers feature patented blade geometry and a larger diameter, which provides better efficiency, acceleration, and handling. They also tend to operate more quietly and smoothly than the previous A and B series designs.

When should I replace my DuoProp propellers?

Replace your propellers if you notice significant performance loss, increased vibration, or visible damage such as bent blades, large dings, or signs of severe corrosion. Even minor damage can affect performance and fuel economy.

What are the signs of a damaged or failing propeller?

Common signs include new or excessive vibration, a drop in top speed or RPM, poor acceleration ("cavitation burn"), and reduced fuel efficiency. Visually inspect for bent, chipped, or cracked blades, especially after a suspected impact.

Can I use this aluminum propeller set on a high-performance engine?

No. This aluminum propeller set is rated for gasoline engines up to a maximum of 240 HP and speeds up to 38 knots (45 mph). For higher horsepower applications, you must use the recommended Type C stainless steel propellers to prevent blade failure.

How do I choose between a J9, J10, or other size?

Your choice depends on your previous propeller type. If you had an A-series prop, the number generally matches (A10 ≈ J10). If you had a B-series, you typically go one size larger in the J-series (e.g., B9 ≈ J10). Consult your manual or a marine technician if unsure.
