FAQ Propellers
How do you change a boat propeller?
- Secure the motor: raise it and wedge it in place
- Remove the pin and propeller mounting nut
- Remove the propeller by pulling it forward
- Clean the propeller shaft and check the condition of the seals
- Install the new propeller with grease
- Refit the nut and tighten to the recommended torque, and don't forget the safety pin
Important: Always wear gloves and make sure the engine is turned off. Keep spare pins on board.
How to choose a boat propeller?
Essential criteria:
- Diameter and pitch: depending on engine power and use
- Number of blades: 3 blades (speed) or 4 blades (torque)
- Material: aluminum (economical, recommended up to 150 hp) or stainless steel (performance, recommended from 115 hp)
Basic rule: The propeller must allow the engine to reach its maximum speed. Too high a pitch overloads the engine, too low a pitch limits speed.
Our advice: Consider your intended use (cruising, water sports, fishing) and consult our technical team for personalized advice.
How to repair a boat propeller?
Possible repairs:
- Slightly damaged blades: sanding and polishing
- Small cracks: welding by a professional
- Minor deformation: straightening by a specialist
Repair limitations:
- Avoid repairs on significant damage
- An unbalanced propeller can damage the engine
- Makeshift repairs are not recommended
Our recommendation: For your safety and that of your engine, replace a severely damaged propeller. Discover our range of replacement propellers suitable for all engines.
FAQ Hydrofoils
How does the hydrofoil work?
The hydrofoil generates hydrodynamic lift by channeling the flow of water under your boat. Placed in the propeller's flow, it creates a vacuum on its upper surface that literally "sucks" your boat upward.
The result: your boat requires less power to reach cruising speed and maintains optimal trim even at low speeds. The effect is particularly noticeable on heavy hulls or boats with a rear center of gravity.
How to install a hydrofoil?
Simple installation without modifying the engine:
- Position the hydrofoil on the anti-cavitation device, perfectly centered
- Mark the drilling points with the template provided
- Drill the holes to the specified dimensions
- Secure with the stainless steelbolts provided (torque 25-30 Nm)
Time required: 20-30 minutes with standard tools. No irreversible modifications to the engine.
Important: Check compatibility with your engine and follow the manufacturer's instructions. Installation does not require any permanent modifications to the engine.
How to choose a hydrofoil for your outboard motor?
Selection according to your engine:
- Up to 50 hp: Compact model to avoid overload
- 50-150 hp: Standard size, maximum efficiency
- Over 150 hp: Large surface area for high stress
According to your boat:
- Lightweight/sporting hull: Priority given to responsiveness
- Heavy/family hull: Maximum lift for planing assistance
- Fishing boat: Stability preferred for holding position
Our advice: The power of your engine and the weight of your boat are the determining factors. Contact us with your specifications for personalized advice.
FAQ Outboard Parts
What oil should I use for 2-stroke and 4-stroke outboard engines?
For a 2-stroke outboard engine, use only a specific 2-stroke marine oil that meets TC-W3 or NMMA standards. This oil is formulated to withstand the marine environment and ensure optimal lubrication.
Recommended oil types:
- 2-stroke engine oil: mixed with gasoline (usually 2% or 1% depending on the model)
- 4-stroke engine oil
- Sump oil: specific lubrication for the sump and gears (SAW 90 or equivalent)
Always consult your engine manual for exact specifications. Our experts can advise you on the right oil for your engine brand (Mercury, Yamaha, Suzuki, etc.).
How can you maintain the power of an outboard motor?
There are several ways to optimize the performance of your outboard motor:
Maintenance:
- Replace spark plugs regularly for optimal ignition
- Replace oil and fuel filters regularly
- Check and inspect the carburetor or injectors
- Use high-quality gasoline and oils
- Check the condition of the anodes to prevent corrosion
Propeller optimization:
- Choose a propeller with the right pitch and diameter for the size of your boat
- A propeller in poor condition significantly reduces performance
Important: Always comply with the manufacturer's limits and applicable regulations.
How to choose an outboard propeller?
The choice of propeller is crucial to the performance of your engine. Here are the essential criteria:
Parameters to consider:
- Diameter: determines the propulsion surface area
- Pitch: theoretical distance traveled in one revolution (affects speed vs. torque)
- Number of blades: 3 blades (speed) or 4 blades (torque and stability)
- Material: aluminum (economical) or stainless steel (performance and durability)
Basic rules:
- Lower pitch = better torque, improved acceleration
- Higher pitch = higher top speed
- The propeller must allow the engine to reach its maximum recommended speed
Our advice: Consider your intended use (water skiing, cruising, fishing) and the characteristics of your boat (weight, hull shape). Our technical team can help you select the perfect propeller for your configuration.
