Metric Units:
- Meters (m): Length (1 m ≈ 39.37 in)
- Kilometers per hour (km/h): Speed (1 km/h ≈ 0.621 mph)
- Kilograms (kg): Weight (1 kg ≈ 2.205 lb)
- Inches (in): Length (1 in ≈ 0.0254 m)
- Miles per hour (mph): Speed (1 mph ≈ 1.609 km/h)
- Pounds (lb): Weight (1 lb ≈ 0.454 kg)
Understanding Your Results
- Propeller Diameter: Width of the propeller’s blade circle. Larger diameters suit heavier boats or low-speed performance.
- Propeller Pitch: Distance the boat moves forward per revolution. Lower pitch improves hole shot; higher pitch increases speed.
- Blade Count: Number of blades (3 or 4). 4-blade props offer better thrust for hole shot; 3-blade for top speed.
- Material: Aluminum (cost-effective, lighter) or stainless steel (durable, high-performance).
- Propeller Series: Yamaha series (e.g., Reliance, Talon) for your boat and goal.
- Rotation: Direction of prop spin (RH = right-hand). Dual-engine boats may need LH.
- Propeller Slip: Difference between theoretical and actual travel (5–20% typical for outboards).
- WOT RPM: Engine RPM at full throttle. Should be within Yamaha’s recommended range (e.g., 5000–6000 for F150).
- Top Speed: Estimated maximum speed with the recommended propeller.
