390237 – Propeller – OMC

The 390237 OMC propeller is a genuine aluminum propeller designed for classic OMC, Johnson, and Evinrude outboard motors. This three-blade prop measures 8½″ in diameter with a 9″ pitch, making it suitable for smaller outboards, typically in the 4 HP to 8 HP range that use pin-drive and non-thru-hub setups. It offers good all-around performance for lightweight boats and dinghies where smooth acceleration and reliable thrust matter.

Propellers are essential for translating engine power into forward or reverse motion through water. When the original prop becomes bent, chipped, or worn, it can reduce top speed, cause vibration, and lower fuel efficiency. Installing the 390237 OMC propeller restores proper thrust and helps your boat perform as intended. To use, simply slide it onto the prop shaft and secure it with the correct nut and washer hardware. This part fits pin-drive gearcases where the hub seals and thrust washer match older vintage outboards.

This propeller’s aluminum construction provides durability while still remaining lightweight. It resists corrosion better than untreated steel and handles regular freshwater and saltwater use when rinsed after every trip.
