No complete 45 HP outboard motor is listed among these products. For owners of a 45 HP engine, the Mercury-compatible impeller kit and 25–70 HP propeller may be relevant, subject to confirming the motor’s model and specifications. The remaining products are lower-power alternatives: the 18 HP HangKai is best for buyers seeking more output than the 9 HP options, while the two 9 HP motors suit smaller boats and different maintenance preferences.
| Product | Best suited for | Important detail |
|---|---|---|
| OULEME Aluminum Propeller | Checking propeller replacement options | Listed for Mercury 25–70 HP; 10 7/8 x 11 inches |
| QUICKMARINER Impeller Kit | Water-pump repair on listed engines | Compatibility includes Mercury 30–60 HP |
| HangKai 18 HP Outboard | Buyers considering a lower-power motor | 2-stroke, 18 HP |
| YYHGTRD 9 HP Outboard | Buyers prioritizing 4-stroke operation | 224cc, air-cooled |
| FXEIPOL 9 HP Outboard | Buyers wanting tilt and rotation features | 224cc, 4-stroke |
OULEME Aluminum Propeller
This three-blade, right-hand-rotation aluminum propeller is listed as a replacement for Mercury 25–70 HP outboards with a 3 1/4-inch gearcase. Its stated dimensions are 10 7/8 inches in diameter and 11 inches in pitch, with a 13-tooth spline.
Best for: A 45 HP Mercury owner checking a potential replacement propeller. The listed horsepower range includes 45 HP, but that alone does not establish fit. Confirm the engine model, gearcase, spline, rotation, and required pitch before choosing it.
Limitation: The listing’s range does not guarantee compatibility with every 45 HP motor. Do not select a propeller by horsepower alone.
QUICKMARINER Water Pump Impeller Kit
This repair kit is listed for Mercury and Mariner 2- and 4-stroke motors in several horsepower sizes, including 45 HP. It also names Force models. The package includes a rubber impeller, gaskets, a driveshaft key, and washers.
Best for: Owners seeking parts for a water-pump repair on an engine that matches the listed application. It is relevant to a 45 HP search because the stated compatibility range includes 45 HP.
Limitation: Verify the engine’s exact model and original part number against the listing before ordering. The supplied information does not confirm fit for every 45 HP brand or year.
DUIBAII HangKai 18 HP Outboard
This 2-stroke outboard is rated at 18 HP, with a stated maximum output of 13.2 kW and maximum speed of 5,500 rpm. Listed features include an aluminum-alloy construction, a three-blade propeller, and a 6.34-gallon external fuel tank. The product description reports fuel consumption of 1.18 gallons per hour.
Best for: Buyers comparing lower-power gas outboards who want more listed horsepower than the 9 HP choices below. It is not a substitute for a 45 HP motor when a boat requires that output.
Limitation: This is an 18 HP, 2-stroke engine, not a 45 HP model. Confirm the boat’s transom and engine requirements before purchase.
YYHGTRD 9 HP Four-Stroke Outboard
This 224cc, air-cooled engine is listed at 9 HP and 3,600 rpm. Features include manual pull starting, tiller control, 360-degree steering, manual tilt, and reverse by rotating the motor head 180 degrees. Its description specifies pure 92-octane-or-higher gasoline without oil mixing.
Best for: Buyers considering a small-boat outboard who prefer a four-stroke setup and the described steering arrangement. The product listing mentions fishing boats, inflatables, canoes, and other small craft.
Limitation: At 9 HP, it is far below 45 HP. The listing’s stated top speed is not a guarantee for every boat or load.
FXEIPOL 9 HP Four-Stroke Outboard
This 224cc outboard is rated at 9 HP. Listed features include an aluminum construction, air cooling, CDI ignition, tilt functionality, 360-degree rotation, and reverse engaged by turning the front end 180 degrees. The description states a maximum speed of 11.81 mph.
Best for: Buyers comparing a compact 9 HP engine with tilt and rotation features. It is an alternative to the YYHGTRD model when those listed controls are a priority.
Limitation: This is not a 45 HP motor. The supplied product information does not establish that it is appropriate for a particular boat; check the boat manufacturer’s power recommendations.
Buying Guide: Choosing A 45 HP Motor Or Part
Are you looking for a complete 45 HP outboard?
None of the listed complete engines is rated at 45 HP. The outboards shown are 18 HP or 9 HP, and should not be represented as direct replacements for a 45 HP motor. Confirm the required horsepower on the boat’s capacity plate or in its manufacturer documentation before shopping.
How do you check whether a propeller fits?
Compare the motor’s make and model, gearcase size, spline count, rotation direction, diameter, and pitch with the propeller specifications. The OULEME listing names Mercury engines from 25 to 70 HP, but a horsepower match alone is insufficient to confirm fit.
What should you verify before buying an impeller kit?
Match the engine model and year, the existing part number, and the kit’s included components. The QUICKMARINER listing includes 45 HP in its stated Mercury and Mariner range, but buyers should confirm the exact application rather than relying on horsepower alone.
How do 2-stroke and 4-stroke options differ here?
The 18 HP HangKai is a 2-stroke model. The two 9 HP options are described as 4-stroke engines. The YYHGTRD listing says it uses gasoline without oil mixing. Review each engine’s operating and maintenance instructions before choosing.
Frequently Asked Questions
Is any listed motor a 45 HP outboard?
No. The complete outboards listed are rated at 18 HP, 9 HP, and 5 HP. The 45 HP search is better served here by checking the compatible-part listings.
Can the listed propeller fit a 45 HP Mercury?
It may be relevant: the listing specifies Mercury 25–70 HP engines. Confirm the exact gearcase, spline, and propeller requirements for the motor.
Does the impeller kit list 45 HP compatibility?
Yes. The listing includes Mercury and Mariner 30–60 HP models, a range that includes 45 HP. Verify the specific engine and part number before ordering.
Which listed motor has the highest horsepower?
The DUIBAII HangKai is the highest-powered complete outboard in this selection at 18 HP. It is still below 45 HP.
Are the two 9 HP outboards interchangeable?
Not necessarily. They have similar stated displacement and horsepower, but buyers should compare their specifications and confirm suitability for the boat rather than assuming interchangeability.
