The Mercury Black Max is Mercury's proven aluminum propeller line, offering solid all-around performance for recreational boating at an accessible price. The 832828A45 in 15 × 17 delivers dependable efficiency for cruising, general use, and everyday outboard and sterndrive applications. Includes the Flo-Torq II Hub Kit 835257K1 for compatible engines.

Compatible Applications

• Mercury 90–115 HP Command Thrust outboards (requires Command Thrust gearcase)
• Mercury 135–400 HP outboards – selected prop-shaft and hub configurations
• MerCruiser Alpha One sterndrives – selected configurations
• MerCruiser Bravo One sterndrives – selected configurations

Fitment Notice: Confirm engine or drive model, horsepower, gearcase size, prop-shaft diameter, spline count, and current propeller pitch before ordering. Note: 90–115 HP applications require the Command Thrust gearcase — the standard 90–115 HP gearcase uses a different propeller size. Some newer FourStroke and high-horsepower applications require a different Flo-Torq hub kit than the 835257K1 included with this propeller.

Propeller Specifications

• Diameter: 15 in. — suited to mid-size outboard and sterndrive gearcases
• Pitch: 17 in. — the lowest pitch in this Black Max 15-inch family, best for heavier loads or maximizing acceleration
• Blades: 3 — standard configuration for smooth cruising performance
• Rotation: Right-hand (standard for most single-engine applications)
• Aluminum construction offers excellent impact resistance and value for recreational use

When to Replace

• Blades are bent, cracked, or heavily nicked from striking an object
• Noticeable vibration at cruising speed that wasn’t present before
• Reduced top speed or fuel efficiency without another obvious cause
• Changing pitch to bring engine RPM into the manufacturer’s recommended WOT range

Installation Notes

• Inspect the propeller shaft, thrust washer, hub components, and shaft splines before installation
• Apply a light coat of marine grease to the propeller shaft
• Install the correct Flo-Torq hub components for your specific engine or drive — see the included Flo-Torq II Hub Kit 835257K1
• Torque the propeller nut to the specification in your engine service manual
• Check for blade clearance and inspect fasteners before each outing

Parts Desk Insights

The defining specs for 832828A45 are 15 in. diameter × 17 in. pitch, right-hand, 3-blade aluminum. The 17-inch pitch is the lowest in the 15-inch Black Max family — a good starting point for heavier boats or applications where better hole shot matters more than top speed. The most common customer issue is not verifying the gearcase type before ordering, particularly on 90–115 HP engines where Command Thrust and standard gearcases require different prop sizes. Also confirm whether your engine needs a different Flo-Torq hub kit, as the included 835257K1 does not fit all applications.
