How do you produce more torque and thrust at lower propeller RPMs with larger diameter propellers?
You can achieve this by using a 2.3 to 1 ratio belted reduction drive unit from Century Drive Systems, Inc. There are other ratios available for you to choose from. For best results use a high performance engine with a roller cam and lifters designed to operate at 5000 RPM’s. A marine or automotive engine with a belt reduction drive in combination with a composite wide blade propeller is an industry standard. Almost any mechanic can repair an automotive engine with a belted reduction drive unit.
