Description

Mercury MerCruiser Quicksilver 832834A45 is a genuine Black Max aluminum propeller in a 14″ diameter x 23″ pitch, right-hand rotation, 3-blade configuration. Current Mercury family references place Black Max in Mercury’s versatile aluminum prop line, built from patented Mercalloy and designed for strong all-around performance, durability, and easy repair. Current part-specific distributor references identify 832834A45 as the 14 x 23 RH version and show it paired with the Flo-Torq II hub system.

Key Features

• Genuine Mercury Black Max propeller, part number 832834A45.
• 14″ diameter x 23″ pitch, right-hand rotation.
• 3-blade aluminum construction using Mercury’s patented Mercalloy alloy.

• Mercury describes Black Max as a strong general-purpose choice for boats up to 250 HP and speeds under 50 MPH.

Engine Compatibility

Current Mercury-family and distributor references associate this prop with higher-horsepower Mercury and MerCruiser applications that use the Flo-Torq hub system. Current part-specific references commonly list fitment for Mercury / Mariner 90–115 HP Command Thrust, 135–300 HP outboards, and MerCruiser Alpha One and Bravo One sterndrives. Because prop fit depends on hub hardware, gearcase, shaft spline, and performance target, the safest match is by exact engine or drive application rather than pitch alone.

Serial Number Fitment Notice

Verify fitment by engine serial number, drive model, prop shaft, hub kit, and current propeller setup before ordering. With 832834A45, matching diameter, pitch, rotation, and Flo-Torq hub compatibility is the important check, especially when several Mercury props can share similar dimensions but use different hardware or target different RPM ranges.

When This Part Needs Replacement

Replace the propeller when the blades are bent, chipped, cracked, heavily worn, or when performance problems point to incorrect pitch or damaged hub components. Because Black Max props are aluminum and designed for dependable everyday use, they are also a common replacement choice when a damaged prop needs a practical OEM-style solution with good all-around performance. This service guidance is a practical inference supported by Mercury’s positioning of the Black Max family as a durable, repairable, value-oriented prop line.

Installation Notes

Confirm the correct Flo-Torq hub system and installation hardware before mounting. Current Mercury references show Black Max props using Flo-Torq hub options, while current part-specific listings for 832834A45 show Flo-Torq II. After installation, prop selection should still be validated against the engine’s recommended WOT RPM range and the boat’s real-world load and use.

Alternate/Superseded Part Numbers

Current seller references identify 832834A45 as the active OEM number. One current Mercury dealer listing also shows earlier or superseded related numbers including 67874A4, 58426A4, 79578A4, 36008A1, 36010A4, 65480A1, 73512A4, 75160A4, 78124A40, 78124A4, and 78124A45.

Parts Desk Insight

The easy mistake with a prop like this is ordering by diameter and pitch only. For 832834A45, the better match is 14 x 23 RH + Black Max family + correct Flo-Torq hub setup + target engine RPM, because that combination matters more than the printed size alone when you want the boat to run the way it should.
