Troubleshooting & FAQ
What drive is this propeller set for?
This Duoprop set is engineered specifically for Volvo Penta DPS-A drives, which utilize a straight spline for propeller mounting.
Can I use this set for speeds over 35 knots?
No. For boat speeds exceeding 35 knots, it is recommended to use stainless steel propellers, such as the Volvo Penta Type F series, for optimal performance and durability.
What is the difference between Type D and Type I propellers?
Type I is the newer, superseding propeller design from Volvo Penta. This D5 set is a direct aftermarket replacement for the original Type D configuration and offers comparable performance characteristics.
How do I know when it's time to replace my propellers?
Check for visible signs of damage, such as cracks, significant dings, bent blades, or heavy corrosion. A noticeable loss in performance, increased vibration, or reduced fuel efficiency are also strong indicators that a replacement is needed.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). It is built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility and batch-inspected for consistency.
