Lewmar 589751 Replacement Propeller F/300TT Left Hand Product Description
Enhance Your Boat's Maneuverability with the Lewmar 589751 Left-Hand Propeller
Navigating tight marinas or docking in windy conditions becomes effortless when your bow thruster operates at peak performance. The Lewmar 589751 serves as a precision-engineered replacement propeller designed specifically for the 300TT series bow thrusters. Crafted to match the original specifications, this left-hand propeller restores powerful thrust and responsive control, ensuring your vessel handles like new.
Boat owners often overlook propeller wear until it impacts handling, but swapping in this genuine part prevents downtime and costly repairs. Its durable construction withstands the harsh marine environment, from saltwater corrosion to debris impacts, keeping your thruster reliable season after season.
Key Features and Performance Advantages
- Exact OEM Fit: Mirrors the factory propeller for seamless integration with Lewmar 300TT bow thrusters, eliminating vibration or imbalance issues.
- Left-Hand Rotation: Optimized for counter-rotating setups, providing balanced thrust that enhances directional stability during low-speed maneuvers.
- High-Strength Materials: Built from robust alloys resistant to cavitation, erosion, and galvanic corrosion, extending service life in demanding conditions.
- Precision Balancing: Reduces noise and wear on gears and seals, promoting smoother operation and lower energy draw from your batteries.
- Easy Identification: Clear markings ensure quick verification during maintenance, saving time on the water or in the yard.
Unlike generic aftermarket options, this propeller maintains the engineered pitch and blade profile of the 300TT series, delivering up to 20% more efficient thrust compared to worn or mismatched parts. Boaters report crisper response when reversing or holding position against crosswinds, making it a smart upgrade for sailboats, power yachts, and workboats alike.
Perfect Compatibility and Straightforward Installation
This propeller fits all Lewmar 300TT bow thruster models, including vertical and V-series variants commonly found on boats from 30 to 45 feet. Confirm your thruster's side—left-hand for starboard installations in twin setups—to ensure optimal performance.
Step-by-Step Installation Guide
- Power down the thruster and secure the boat to avoid movement.
- Remove the anode and inspect the shaft for straightness or scoring.
- Slide off the old propeller, noting the keyway orientation.
- Align the new 589751 with the shaft flat and secure using the nut, washer, and cotter pin—torque to manufacturer specs for safety.
- Test in neutral water: Run short bursts to check for smooth rotation and no unusual noise.
Most DIY-savvy owners complete this in under 30 minutes with basic tools like a socket wrench and puller. For novices, it's a great confidence-builder that avoids haul-out fees.
Pro Tips for Long-Lasting Performance
To maximize the lifespan of your Lewmar 589751 propeller:
- Inspect quarterly for nicks, bends, or fouling—clean with a soft brush and marine polish.
- Replace the sacrificial anode annually or when 50% eroded to protect against electrolysis.
- Monitor zinc levels in saltwater; low zinc accelerates propeller pitting.
- Avoid running in shallow water with silt or weeds to prevent premature wear.
- Pair with fresh gearbox oil changes for holistic thruster health.
Early detection of issues like reduced thrust or grinding sounds can save your propulsion system. Many skippers keep a spare onboard for peace of mind during extended cruises.
Troubleshooting Common Bow Thruster Propeller Problems
If your 300TT thruster feels sluggish:
- Debris缠绕: Line or kelp—stop immediately, clear manually.
- Imbalance: Worn blades cause vibration; replace promptly.
- Seized Shaft: Apply penetrating oil and gently tap free.
- Overheating: Shorten burst times; check electrical connections.
Switching to the 589751 resolves 90% of performance dips, often outperforming universals due to its tailored hydrodynamics.
Frequently Asked Questions
What boats is the Lewmar 589751 propeller compatible with?
It fits all Lewmar 300TT series bow thrusters, ideal for vessels 30-45 feet, including sailboats and motor yachts with vertical or V-thruster installations.
How do I know if I need a left-hand propeller like the 589751?
Left-hand rotation is typically for starboard-side thrusters in counter-rotating pairs. Check your original propeller's spin direction when viewed from the front.
Can I install the Lewmar 589751 myself?
Yes, it's a straightforward swap requiring basic tools. Disconnect power, remove the old prop, align the new one on the shaft, and secure with nut and pin. Test afterward.
What material is the 589751 propeller made from?
It's constructed from high-grade marine bronze alloy, offering excellent corrosion resistance and strength against impacts and cavitation.
How often should I replace my bow thruster propeller?
Inspect annually; replace every 2-5 years depending on usage, water conditions, and maintenance. Signs include vibration, noise, or reduced thrust.
Does the 589751 improve thruster efficiency?
Absolutely—its precision design restores full thrust efficiency, reduces power consumption, and minimizes gear strain compared to worn or mismatched props.
What if my propeller is damaged by fishing line?
Clear debris immediately to avoid shaft damage. The 589751's smooth blades shed line easily, but routine checks prevent escalation.
