The Lewmar 589750 counters this with robust engineering that outperforms worn generics. Skip the guesswork of mismatched aftermarket parts; this OEM-quality replacement guarantees authentic fit and function, boosting your confidence on the water. Many skippers report noticeable improvements in handling after installation, especially in crosswinds or crowded anchorages.

Simple Installation Steps

Replacing your propeller is a straightforward DIY task for most boaters. Begin by powering down and disconnecting the thruster. Remove the old propeller by loosening the nut and sliding it off the shaft—use a propeller puller if it's seized. Clean the shaft thoroughly, then align the new 589750 keyway, slide it on, and torque to manufacturer specs. A dab of marine grease on the shaft prevents future corrosion. Test in neutral water before heading out to verify smooth operation.

1. Disconnect power and access the thruster tunnel
2. Remove cotter pin, nut, and washer from the shaft
3. Inspect and clean the shaft and keyway
4. Install new propeller, washer, nut, and secure with cotter pin
5. Reconnect power and perform a dry run test

Maintenance Tips for Longevity

To maximize the lifespan of your Lewmar 589750 propeller, inspect it annually or after grounding incidents. Rinse with fresh water post-use to remove salt buildup, and check for dings or pitting. Anode maintenance on the thruster complements this, protecting against galvanic corrosion. With proper care, this propeller can outlast multiple seasons, keeping your 300TT thruster ready for adventure.
