48-823663 48-823664 MerCruiser Bravo Three Classic 22P Stainless Steel Propeller Set – 3+3 Blade | Genuine Used Part

🔧 Product Description

Genuine MerCruiser Bravo Three Classic 22-Pitch Stainless Steel Propeller Set - Part Number: 48-823663 / 48-823664

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 set uses a 15 3/4 x 22 front propeller and 14 1/4 x 22 rear propeller. The A60 matte and L cupped suffixes have different Mercury conversion recommendations, so the exact markings on both used propellers must be checked before replacement.

🔌 Function

The matched propellers convert drive torque into straight, efficient thrust. The 22-pitch set is generally used on boats capable of carrying more pitch than the 20P set while remaining within the engine's full-throttle RPM range.

⚠️ Common Signs of Failure

• Front or rear blades are bent, cracked or cavitation-damaged
• Front and rear propellers are mismatched by pitch, cup or generation
• Propeller splines or thrust faces are worn
• Vibration develops after impact damage
• Old 3+3 and new 4+3 propeller generations have been mixed
