Troubleshooting & FAQ
What are the advantages of the J-Series over older A and B series propellers?
The J-Series propellers offer significantly improved strength, durability, and corrosion resistance due to their squeeze-cast aluminum construction and advanced 4-layer paint finish. They provide the same excellent performance and grip as older series but with a reduced risk of cavitation damage.
Can I use a J-series propeller with an A or B series on the same drive?
No. You must not mix Type A, B, and J propellers on the same drive. Always use propellers of the same type and size. For twin-drive installations, both drives must have matching propeller sets.
What is the power and speed limit for this aluminum prop set?
This propeller set is recommended for boats with engines up to 240 hp or those that operate at speeds below 38 knots (45 mph). For engines exceeding these limits, Volvo Penta recommends using their Type C stainless steel propellers for better durability and performance.
How do I know if the J4 size is equivalent to my old props?
The J-series numbering is approximately equivalent to the old A-series numbering (e.g., A4 is comparable to J4). The B-series is roughly one size smaller, meaning a B4 would be replaced by a J5. Always verify the correct size for your specific engine and boat combination.
What are signs that my Duoprop propellers need replacement?
Signs of worn or damaged propellers include increased vibration, a drop in top speed or acceleration, worsened fuel economy, or visible damage such as bent blades, nicks, or signs of cavitation (pitting). Damaged props can cause further harm to your drive, so inspect them regularly.
