3 Blades or 4 Blades? |
We recommend 3-blade propellers for recreational boats with 3, 4, and 6 cylinder outboards and I/O engines. These propellers provide good "hole shot" and top-speed performance. We recommend 4-blade propellers for bass boats and boats with high performance hulls running high horsepower outboard engines. Compared to 3 blades, they provide better "hole shot" performance with less steering torque and less vibration at high speeds. When switching from a 3 blade to a 4 blade, remember to drop 1 inch in pitch to keep the RPM's as close to the same as possible. |
How can I be sure my motor is operating within the recommended rpm range? |
This can only be checked with a tachometer. There are various kinds commercially available. |
