Quicksilver Nemesis 4-Blade Aluminum Propeller - Aggressive

In this review the Quicksilver Nemesis 4-Blade Aluminum Propeller is assessed as a focused aftermarket option for Mercury and MerCruiser powered pontoons and small runabouts. The bottom line: this prop delivers faster plane speed and confident hole-shot for boats that match the engine range, and it is worth considering when top-end speed and quick acceleration matter. Reviewers repeatedly note strong performance in staying on plane at low speeds and reaching high cruise speeds without sacrificing build quality.

Key Features

• 13.8 in diameter, 11 in pitch: The combination is tuned to balance strong acceleration with a high plane speed for light to medium displacement boats.
• Aggressive 4-blade design: Four blades with high rake angles and added cup produce tenacious holding and quicker hole-shot from a standstill.
• Right-hand rotation: Designed for common Mercury installations, it spins right-hand to match compatible lower units without modification.
• Aluminum with black finish: Lightweight aluminum construction offers corrosion-resistant performance with an attractive black coating.
• Engine compatibility: Built for use with 40-60hp Command Thrust and 75-125hp Mercury pontoon engines so buyers can match prop selection to their motor range.
• Manufacturer part number: Supplied as part number 8M8027498 to help ensure correct ordering and hub selection.

Who It's For

The Nemesis propeller is best for owners of small to mid-size pontoons and runabouts powered by Mercury or MerCruiser engines in the specified horsepower bands who want quicker planing, stronger hole-shot and improved midrange throttle response. It is especially useful for boats around 20 ft where customers reported staying on plane at slower speeds and reaching higher cruise speed at moderate rpm.

Those who need the absolute maximum fuel efficiency or who run heavy displacement loads year-round should compare other pitch and blade-count options or consult the hub selection grid for exact fitment. Also, buyers with non-Mercury lower units should confirm compatibility before purchasing.

Pros & Cons

Pros

Frequently Asked Questions

Will this prop fit my Mercury engine?
It fits specified 40-60hp Command Thrust and 75-125hp Mercury pontoon engines but you must consult the hub selection grid for the correct hub and lower unit match.

Is the aluminum blade durable enough?
Aluminum with a black finish provides good corrosion resistance and performance, though stainless steel can offer greater impact resistance if you frequently encounter debris.

What performance changes should I expect?
Expect quicker hole-shot, better midrange response and higher plane speed at comparable rpm based on customer experiences with similar boats.
