48-823665 48-823666 MerCruiser Bravo Three Classic 24P Stainless Steel Propeller Set – 3+3 Blade | Genuine Used Part

🔧 Product Description

Genuine MerCruiser Bravo Three Classic 24-Pitch Stainless Steel Propeller Set - Part Number: 48-823665 / 48-823666

A genuine used matched MerCruiser Bravo Three pre-2008 stainless-steel propeller set with a three-blade left-hand front propeller and three-blade right-hand rear propeller.

The original matte 24-pitch set uses a 15 1/2 x 24 front propeller and 14 1/4 x 24 rear propeller. Cupped L-suffix versions convert to a different current pitch, so both propeller markings must be verified before replacing only one member of the pair.

• Front and rear propellers are mismatched by pitch, cup or generation
