48-823661 48-823662 MerCruiser Bravo Three Classic 20P Stainless Steel Propeller Set – 3+3 Blade | Genuine Used Part

🔧 Product Description

Genuine MerCruiser Bravo Three Classic 20-Pitch Stainless Steel Propeller Set - Part Number: 48-823661 / 48-823662

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 20-pitch set uses front propeller 48-823661 and rear propeller 48-823662. The suffix and cup condition must be checked because the matte A60 pair and cupped L pair convert to different current-generation pitches. Old 3+3 propellers should not be mixed with the later 4+3 generation.

🔌 Function

The two propellers rotate in opposite directions to recover swirl energy and generate straight thrust. The matched 20-pitch set provides strong acceleration, low-speed control and manoeuvrability for heavier or lower-speed Bravo Three applications.

• Front and rear propellers are mismatched by pitch, cup or generation
• Propeller splines or thrust faces are worn
