19M2 ¾ 13 Propeller
Product description
The 13 ¾ × 19-M2 Propeller — with a three-blade design, high pitch, and ultra-durable stainless steel material — delivers high cruising speeds, strong acceleration, and exceptional durability for your 200 HP boat. A dependable choice for high-speed commercial operations or high-performance recreation in corrosive marine environments.
Product Summary
1. The 13 ¾ × 19-M2 propeller is designed for Yamaha 200 HP engines and delivers peak performance on high-speed commercial and high-performance recreational boats.
2. Its 13 ¾-inch diameter and 19-M2 pitch enable higher top-end speeds (up to 45 mph) while maintaining mid-range thrust — ideal for long routes and heavy-duty operations.
3. This model is available in stainless steel, with a dual-layer epoxy coating highly resistant to saltwater corrosion.
4. Stable operating range is 2500–3000 rpm and it runs up to 5500 rpm without cavitation, keeping the engine in its power sweet spot.
5. At speeds of 35–45 mph, the stainless steel version showed up to 7% lower fuel consumption compared to a same-diameter 17-pitch aluminum propeller.

Torque
● Three-blade design with reinforced root, despite the high 19-M2 pitch, produces up to 210 N·m of effective torque at low RPM (200 HP engine); sufficient to pull a heavy boat out of the water (Hole-Shot) without cavitation.
● 12° rake combined with adaptive camber creates a smooth spiral flow path and reduces energy loss by up to 6% compared to propellers without rake (or rake less than 12°).
● 12° rake combined with adaptive camber creates a smooth spiral flow path and reduces energy loss by up to 6% compared to propellers without rake (or rake less than 12°).
Horsepower Utilization
● The 19-M2 pitch keeps the engine in the 5450–5000 rpm range (power peak), ensuring higher top speeds and optimized cruising fuel consumption.
● Steady 40 mph test with a 200 HP engine recorded 13.2 L/h fuel consumption for the steel version and 14.4 L/h for the aluminum version.
● In calm seas, no vibration or cavitation was observed up to the maximum rated RPM.
● Steady 40 mph test with a 200 HP engine recorded 13.2 L/h fuel consumption for the steel version and 14.4 L/h for the aluminum version.
● In calm seas, no vibration or cavitation was observed up to the maximum rated RPM.
Flexibility
● Stainless steel: 790 MPa yield strength and 14% elongation; resists bending or cracking under moderate impacts.
● Hybrid-resin hub with rubber bushing absorbs up to 60% of torsional shock, protecting the gearbox.
● Hybrid-resin hub with rubber bushing absorbs up to 60% of torsional shock, protecting the gearbox.
Durability
● Dual-layer epoxy coating (on both versions) guarantees up to 800 hours of ASTM B117 salt spray resistance.
● 150-hour continuous test at 5000 rpm showed no measurable pitch change or cracking.
● 150-hour continuous test at 5000 rpm showed no measurable pitch change or cracking.
