Engine RPM, shaft speed and propeller diameter
Sailboat propeller shaft speeds are typically between 850 – 1650 shaft RPM (they are not speed boats). Faster shaft speeds […]

If too large the propeller will absorb the hp too early and hold the RPM down, causing the engine to “lug”, […]
Too small a propeller will produce very low torque, poor thrust and low speed at the stated RPM. The engine’s […]
