If you need a 125 hp boat motor, none of the listed engines is rated at 125 hp. The closest match is an aluminum propeller listed for Mercury outboards from 60 to 125 hp; confirm fitment with your exact motor before ordering. The other options are lower-power engines or a small-craft trolling motor, so they are alternatives for different boating needs—not substitutes for a 125 hp outboard.
| Product | Listed power or fit | Best suited for |
|---|---|---|
| Qiclear aluminum propeller | Mercury 60–125 hp | Owners checking propeller options for a compatible Mercury motor |
| HangKai outboard | 18 hp, two-stroke | Small boats needing a gas outboard |
| Outboard engine | 6.5 hp, four-stroke | Light-duty small-craft use |
| Newport NV-Series trolling motor | 36 lb thrust | Quiet propulsion for lightweight craft |
| Outboard engine | 9 hp, four-stroke | Small boats where manual tiller steering is useful |
Qiclear 13 1/4 x 17 Aluminum Propeller
Best for: Owners of a Mercury outboard in the listed 60–125 hp range who need a replacement propeller option. This is the only listed product specifically associated with a 125 hp motor, but it is a propeller, not an engine.
The listing specifies a 13 1/4-inch diameter, 17-inch pitch, right-hand rotation, three blades, 15 spline teeth, and aluminum construction. It gives reference number 48-77344A45 and says it is for Mercury outboards rated from 60 to 125 hp.
Limitation: Horsepower range alone does not confirm fit. Verify the motor’s make, model, shaft and hub requirements, and existing propeller specifications before choosing it.
HangKai 18 HP Two-Stroke Outboard
Best for: Buyers seeking a compact gas outboard for a smaller boat, rather than a 125 hp engine. It is selected as a lower-power alternative because its listed 18 hp rating is clearly specified.
The two-stroke engine has CDI ignition, a maximum output of 13.2 kW, and a listed maximum speed of 5,500 rpm. Its aluminum-alloy construction and three-blade, 8-inch propeller are described in the listing. It includes an external 6.34-gallon fuel tank; the stated fuel consumption is 1.18 gallons per hour.
Limitation: At 18 hp, this motor is not appropriate when a boat requires 125 hp. It is a two-stroke engine, so confirm fuel and operating requirements in the product documentation.
6.5 HP Four-Stroke Outboard Motor
Best for: Buyers looking for a low-power engine for an inflatable boat, kayak, canoe, or other small craft. The listing describes a 6.5 hp, 123 cc four-stroke motor with water cooling and CDI ignition.
Features include a three-blade propeller, manually controlled steering and tilt, and a reverse gear. The seller states a load capacity of 661–1,653 pounds and a maximum transom thickness of 1.57 inches for its mounting clip. Plastic and aluminum-alloy components are described as corrosion- and wear-resistant.
Limitation: Its 6.5 hp rating is far below 125 hp. The listing also notes that the motor ships in two packages, so delivery may not arrive as a single package.
Newport NV-Series 36 lb Thrust Trolling Motor
Best for: Small-craft owners who want quiet electric propulsion for a kayak, canoe, inflatable, or lightweight boat. This product is rated by thrust, not horsepower, so it should not be compared directly with a 125 hp outboard.
The listing specifies 36 pounds of thrust and 12V or 24V operation. It features a two-blade propeller designed for efficient movement and corrosion-resistant construction for freshwater and saltwater use. An LED battery indicator is included in the product name.
Limitation: It is intended for lighter setups and depends on a suitable battery. Choose a gas outboard instead if your boat needs substantially more propulsion.
9 HP Four-Stroke Outboard With Tiller Steering
Best for: Small-boat buyers who prefer a four-stroke engine and manual tiller control. The listing gives a 224 cc engine, 9 hp at 3,600 rpm, and air cooling.
Its tiller offers 360-degree steering, and the motor uses a 180-degree turn of the motor head for reverse. The listing also describes manual tilt, a 0.34–0.4-gallon built-in tank, and operation on pure 92-octane-or-higher gasoline without oil mixing. It states a top speed of 11.8 mph.
Limitation: The stated speed is listing information, not a guarantee for every boat or load. This 9 hp engine is not a replacement for a 125 hp motor.
Buying Guide: How To Choose A 125 HP Boat Motor
Do these products include a 125 hp engine?
No. The listed gas engines are 6.5, 9, and 18 hp, and the Newport product is an electric trolling motor rated at 36 pounds of thrust. Only the Qiclear propeller listing mentions a 60–125 hp range. If you need a complete 125 hp outboard, search for an engine explicitly rated at 125 hp.
How should you check propeller fit?
Do not rely on horsepower range alone. Compare the propeller’s diameter, pitch, rotation, spline count, and reference number with your existing propeller and the outboard manufacturer’s specifications. Check the exact make and model, and consult a marine mechanic or dealer if any details are uncertain.
Should you choose an electric or gas motor?
An electric trolling motor is listed for quiet, controlled movement on lightweight craft and requires a compatible battery. Gas outboards offer a different power source and are described by horsepower. These categories are not directly interchangeable: choose based on your boat’s requirements, intended use, and manufacturer guidance.
What else should you verify before buying?
Confirm the boat’s recommended horsepower range, transom dimensions, engine weight and mounting needs, steering arrangement, and fuel or battery requirements. For gas engines, check the product instructions for fuel, cooling, and operation. Never select a lower-power engine as a substitute if the boat requires 125 hp.
Frequently Asked Questions
Which listed product is for a 125 hp boat motor?
The Qiclear 13 1/4 x 17 aluminum propeller is listed for Mercury outboards from 60 to 125 hp. It is a propeller, not a 125 hp engine.
Can an 18 hp outboard replace a 125 hp motor?
No. An 18 hp engine has much less rated power. Use only an engine within the boat manufacturer’s recommended horsepower range.
Is 36 pounds of trolling thrust the same as 36 horsepower?
No. Pounds of thrust and horsepower are different measures. The Newport motor is specified by thrust and should not be treated as a 125 hp outboard.
Will the Qiclear propeller fit every 125 hp Mercury outboard?
The listing gives a Mercury 60–125 hp range, but that does not guarantee fit on every model. Confirm the propeller dimensions and hub specifications against your exact motor.
What information should I have before buying a replacement propeller?
Record the outboard’s make and model and the current propeller’s diameter, pitch, rotation, spline count, and part or reference number. Match those details to the manufacturer’s specifications.
