THE RIGHT PROPELLER = PEAK PERFORMANCE
Your propeller is a key factor in your boat’s performance, and your satisfaction. Maintain it for peak power, performance, and efficiency. Let’s review the products to use and steps to take to keep your propellers in great shape.
CHOOSE YAMALUBE®
A high-quality, non-building, synthetic, aerosol lubricant with PTFE. Highly resistant to heat and friction, it’s ideal for lubricating control cables.
Shop Yamalube products at your nearest authorized Yamaha Marine dealer.

Your propeller is in almost constant contact with the water. It’s important to use products that are formulated to withstand extremely punishing marine conditions.
Yamalube greases are engineered to prevent corrosion and rust, resist wash off, heat, pressure, and harsh marine conditions. They provide maximum, long-lasting, water-resistant lubrication.

DO IT YOURSELF
Something missing? If you’ve noticed a decrease in your boat’s performance, but your outboard checks out fine, inspect your prop. Grit, sand, and silt in the water slowly eat away at your propeller’s edges. Your prop may look perfect, but the worn edges can degrade performance.
Beware corrosion. It’s easy to clean and protect most props. Try these simple tips:
- Rough Cast Mag Wheel Cleaner. Spray on (don’t let dry or sit for more than 30 seconds) and agitate with dish sponge. Rinse thoroughly, dry, apply paste wax.
- Toilet Bowl Cleaner, Hydrogen Peroxide, or Calcium Lime & Rust Remover. For spot cleaning, spray on or put on a rag and wipe over stained area (don’t let dry). Rinse thoroughly, dry, and follow up with paste wax.
- Mild Rubbing Compound or Metal Polishing Paste. For difficult stains: apply to pad and rub in a circular motion until stain is diminished. Buff with a clean cloth, apply paste wax.
NOTICE: When using any of these methods, be sure to read the product label and follow all precautions provided.
Periodically remove your propeller(s) to check for fishing line wrapped around the prop shaft. Then grease the prop shaft with a high-quality, high-pressure marine-formula grease like Yamalube Marine Grease or Yamalube Molybdenum Disulfide Grease. This should make it easier to get the prop off next time, especially in saltwater. When reinstalling, make sure to torque the prop nut to the manufacturer’s specification, and always use a new cotter pin rather than reusing the old one.
Remember, you can use your prop to dial in the performance of your rig to match your boating style and environment. So, if you boat on a variety of waterways, or use your boat for different applications, it’s nice to have props to match those uses.
Also, keeping a spare propeller is handy for emergencies, for example, if you chip a blade on a rock.
