Q1: How do I ensure this propeller fits my outboard motor perfectly?
* A: To guarantee a precise match, please verify the following 4 details:
1. Brand, Horsepower (HP), and Year: Confirm your engine brand (e.g., Yamaha, Mercury, Suzuki, Tohatsu), exact horsepower, and production year.
2. Spline Count (Tooth Count): The number of teeth on your propeller shaft must match exactly (e.g., 13-tooth or 15-tooth are common for mid-range motors).
3. Dimensions / OEM Part Number: Check the hub or blades of your current prop for stamped numbers like 11 1/8 x 13 (Diameter x Pitch) or the factory OEM part number.
* uD83DuDCA1 Quick Help: If you are unsure, simply take a photo of your engine's serial number plate or the stamped markings on your old propeller, and send it to our customer service. We will match it for you for free!
Q2: Aluminum vs. Stainless Steel Propellers: Which one should I choose?
* A: Both materials offer unique benefits depending on your boating environment:
* Aluminum Propellers: Best Value & Engine Protection. They are highly cost-effective and lightweight. If you accidentally hit a rock or underwater obstacle, the aluminum blade will sacrifice itself (bend or break) to protect your expensive lower unit gears from severe damage. Ideal for casual recreation and shallow-water boating.
* Stainless Steel Propellers: Peak Performance & High Durability. They are extremely rigid. The blades can be made thinner without flexing under heavy loads, providing superior thrust, faster hole shots, and higher top speeds. They also offer top-tier corrosion resistance, making them perfect for high-speed performance, heavy loads, or long-term saltwater use.
Q3: How does changing the propeller "Pitch" affect my boat's performance?
* A: Think of pitch like the gears in a car:
* Increasing Pitch (Higher Gear): Best for light loads. It will maximize your top-speed, but it reduces your initial
acceleration (hole shot) and lowers the engine's Maximum RPM.
* Decreasing Pitch (Lower Gear): Best for heavy loads (e.g., water skiing, towing, multi-passenger fishing). It provides
stronger low-end thrust and a faster hole shot, but your top speed will be limited.
* The Golden Rule: The right pitch should allow your engine to run safely within its recommended Wide Open Throttle (WOT) RPM range.
Q4: Are your propellers treated for anti-corrosion?
* A:
* Absolutely. Our aluminum propellers are cast from high-strength Marine-Grade aluminum alloy. The surface undergoes shot blasting, a chemical conversion base coat, and a multi-layer electrostatic powder coating process. This heavy-duty finish has passed rigorous salt spray tests, effectively resisting saltwater corrosion and electrochemical degradation in harsh marine environments.
Q5: What is the handling time and shipping schedule?
* A:
* Handling Time: In-stock products are typically shipped within 2-5 business days. For custom orders, OEM branding, or bulk wholesale purchases, please contact our team to confirm the production timeline.
* Estimated Shipping Time:
* Express (DHL / FedEx / UPS): 5-9 days. Best for urgent replacements.
* Air Freight: 10-15 days. A great balance of speed and cost.
* Sea / Rail Freight: 25-45 days depending on the destination. Highly recommended for bulk orders to minimize your shipping costs.
Q6: Can I return or exchange the propeller if it does not fit?
* A:
* Order Protection: We fully support Alibaba Trade Assurance (or platform-specific buyer protections) to ensure your payment and order security.
* Return Policy:
* Our Mistake: If the propeller cannot be installed due to an incorrect recommendation by our team or a quality issue, we
provide a full refund or free replacement, and we cover all return shipping costs.
* Buyer Selection Error: If you accidentally purchased the wrong model, we accept returns/exchanges within 14 days,
provided the item is in resalable condition. In this case, the buyer is responsible for round-trip shipping fees.
* ⚠️ Crucial Note: Upon arrival, please visually check the spline count and hub shape against your shaft before attempting installation. Do not force it onto the shaft or apply grease. Products with scratches, paint chips, or installation marks on the splines cannot be accepted for a full refund or exchange.
