Installation Notes
This kit is a direct bolt-on fit for compatible drives. For safety and performance, do not mix these J-series propellers with older A or B series props on the same drive. If you have a twin-engine application, ensure both drives are fitted with the same propeller type. Note that this propeller set is not recommended for engines exceeding 240 horsepower or boats capable of speeds above 38 knots (45 mph).
Troubleshooting & FAQ
What drives does this propeller kit fit?
This DuoProp J7 kit is engineered for Volvo Penta 280 DP and 290 DP drives running on gasoline engines.
Can I use this J7 prop set with my old A or B series propellers?
No. While this kit replaces A and B series props, you should not mix different propeller types on the same drive. Always replace props as a complete set.
Is this propeller suitable for high-speed applications?
This kit is not recommended for engines that exceed 240 hp or for boats that can travel faster than 38 knots (45 mph).
What is the difference between the front and rear props?
The front propeller (21924227) has a left-hand rotation and a 27-tooth spline. The rear propeller (21924247) has a right-hand rotation and a 19-tooth spline. This DuoProp design provides counter-rotating thrust for improved handling and efficiency.
How do I know when to replace my props?
Inspect your propellers regularly for visible damage such as significant nicks, dings, bent blades, or advanced corrosion. Performance issues like increased vibration, loss of speed, or poor fuel economy are also key indicators that a replacement is needed.
What’s the difference between OEM and aftermarket parts?
This listing is for an aftermarket replacement, not an original equipment manufacturer (OEM) part. It is built to meet or exceed OEM specifications using comparable materials in an ISO 9002 certified facility and is batch-inspected to ensure quality and performance.
How much is shipping and how long does it take?
We offer fast worldwide shipping, with typical transit times between 5 and 15 days. Standard shipping is free for most orders. If available for your location, expedited shipping options will be presented at checkout.
