To calculate the airboat prop speed:
\[ PS = \frac{RPM}{GR} \]
Where:
Prop speed is defined as the total rotations per minute an airboat propeller is spinning at given an engine RPM and a gear reduction.
Let's assume the following values:
Step 1: Divide the engine RPM by the gear reduction:
\[ PS = \frac{3000}{2} = 1500 \text{ RPM} \]
