Can I install this propeller myself, or do I need a technician?

Yes, most users with basic mechanical skills can install the Pro L4 themselves. You’ll need a wrench, marine grease, and your engine manual. However, if you are unsure or installing for the first time, it’s always wise to consult or hire a marine technician to ensure optimal performance and safety.

What are the advantages of using a stainless-steel propeller over aluminum?

Stainless steel propellers, like the Pro L4, are stronger, more durable, and offer better thrust at higher speeds. They resist flexing, meaning more energy is transferred to propulsion. Aluminum is cost-effective but wears faster and may reduce long-term engine efficiency.

What should I do if my Pro L4 gets damaged?

First, stop using the propeller immediately to prevent engine or gearbox damage. Inspect the damage: small nicks may be repairable at a prop shop. For severe damage (e.g., bent blades or cracks), replacement is recommended. Regular inspections can help catch early signs of wear before performance drops.
