2. Laser II Performance Enhancement

  • Optimized blade design for increased speed, fuel efficiency, and acceleration.
  • Reduced drag for better overall performance.

3. 3-Blade Configuration for Speed & Efficiency

  • Ensures high top-end speed and smooth handling.
  • Reduces cavitation and prop slip for better power transfer.

4. Wide Compatibility

  • Suitable for 150HP to 300HP Mercury outboards & sterndrive engines.
  • Works with Bravo One Drive, Alpha One Drive (Gen 1 & Gen 2), and MerCruiser sterndrives.
  • Available with 15-tooth spline for secure fitment.

5. Multiple Diameter & Pitch Options

  • Diameters ranging from 13 3/4" to 16", and pitches from 17" to 25".
  • Allows customization based on load, speed, and water conditions.

6. Right-Hand (RH) & Left-Hand (LH) Rotation Options

  • Suitable for single-engine and twin-engine setups.
  • LH props help reduce torque steer in twin-prop applications.

Installation Instructions

  • Prepare the Boat & Tools:
    • Ensure the engine is turned off and the boat is out of the water.
    • Gather a wrench, marine grease, and safety gloves.
  • Remove the Old Propeller:
    • Use a wrench to loosen and remove the propeller nut.
    • Carefully slide the old propeller off the shaft.
  • Inspect & Lubricate the Shaft:
    • Check for damage, corrosion, or debris.
    • Apply marine grease to prevent future corrosion.
  • Install the New Propeller:
    • Align the spline teeth with the shaft and slide the propeller on.
    • Ensure proper seating before securing.
  • Secure the Propeller:
    • Install the washer and propeller nut, tightening to manufacturer specifications.
    • If applicable, insert the cotter pin for added security.
  • Final Check & Testing:
    • Manually rotate the propeller to ensure smooth movement.
    • Start the engine in water and check for abnormal vibrations.

Precautions

  • Choose the Correct Size: Ensure the diameter, pitch, and spline match your engine’s specifications.
  • Regular Maintenance: Inspect for damage, corrosion, and wear after each use.
  • Avoid Impact Damage: Be cautious in shallow waters and rocky areas.
  • Proper Torqueing: Secure the propeller nut to the correct torque setting to prevent loosening.
  • Monitor Performance: If experiencing excessive vibration, poor acceleration, or decreased top speed, check for improper fitment or propeller damage.

Frequently Asked Questions (FAQs)

1. How do I choose the right Mercury Stainless Steel Propeller?

You need to consider:
  • Engine power (150-300HP)
  • Gearcase compatibility (Bravo One, Alpha One, or MerCruiser sterndrive)
  • Desired performance (higher speed vs. better acceleration)
  • Right-hand (RH) or left-hand (LH) rotation

2. What is Laser II technology, and how does it improve performance?

Laser II propellers feature a special blade design that reduces drag, enhances fuel efficiency, and provides higher top-end speeds compared to standard stainless steel propellers.

3. What are the advantages of a 3-blade vs. 4-blade propeller?

  • 3-blade props (like Laser II): Best for high speed, top-end performance, and fuel efficiency.
  • 4-blade props: Better for low-speed handling, towing, and increased thrust.

4. How often should I replace my stainless steel propeller?

With proper care, a stainless steel propeller can last for years. Replace if you notice cracks, bends, excessive wear, or poor performance.

5. Can I install the propeller myself?

Yes! The installation process is straightforward. However, if you are unsure, consult a marine mechanic.
