This heavy duty marine propeller replaces worn units on thin shaft outboard motors. It gives steady thrust and smooth handling for fishing runners, bass boats, and offshore work where power transfer matters most. You get a single stainless unit ready to bolt onto your current shaft.

✅ eight blade layout catches more water for instant plane lift
✅ corrosion proof aluminum bronze face plate blocks rust damage
✅ precision balanced run reduces cabin vibration at cruise speed
✅ standard bolt pattern installs back on the factory hub kit

💡 How does an 8 blade propeller improve thrust for light load marine applications?
Switching to an eight blade setup is a highly handy fix when your vessel sits heavy or struggles to plane early in the morning. The broader blade area grabs wet water faster while locking your rpm into the ideal power band.
- extra vanes cut slip rate during hard throttle pulls
- lower pitch ratio keeps engine under load at cruise
- forged stainless material handles dock scrapes without denting
- balanced mass prevents drivetrain vibration at full load
