If you are looking for parts for a 15 hp jet outboard, the products listed here are replacement electrical or fuel-system components—not complete outboard motors. The closest matches include stators listed for Mercury 15 hp engines and an injector listing that includes 15 hp EFI jet applications. Check your engine’s model and serial numbers and the part number before ordering.
| Product | Best For | Listed Fitment |
|---|---|---|
| JETUNIT 174-5721 Stator | Mercury 15 hp two-stroke owners checking an exact part match | Mercury 6–25 hp applications |
| KUNOANZ 174-6617A17 Stator | Mercury 15–25 hp two-stroke owners | Mercury 15–25 hp |
| KUNOANZ 855721T8 Stator | Mercury 15 hp owners who can verify the part number | Mercury 6–25 hp two-stroke |
| KUNOANZ 174-6617K1 Stator | Owners whose engine data confirms this stator | Mercury 6–40 hp two-stroke |
| LINGYUE Fuel Injectors | Mercury or Mariner 15 hp EFI jet applications | 15, 25, and 30 hp EFI jet engines |
JETUNIT 174-5721 Stator
This JETUNIT stator is listed for Mercury and Mariner 6, 8, 9.9, 10, 15, 20, and 25 hp two-stroke outboards. The listing gives part numbers 174-5721, 855721T8, and 855721A4, and describes applications including certain jet and two-cylinder models.
Best for: Mercury or Mariner 15 hp owners whose existing part number and engine details match the listing. It is selected because 15 hp is specifically included in the stated range. The listing advises checking recommended part numbers; horsepower alone is not enough to establish fit.
KUNOANZ 174-6617A17 Stator
This stator is listed for Mercury 15–25 hp two-stroke outboards. KUNOANZ emphasizes checking the engine horsepower, model number, and serial number against the engine nameplate because year alone may not identify the correct replacement.
Best for: Owners of a Mercury 15 hp two-stroke who can confirm the engine data and required part number. Its stated range begins at 15 hp, making it a direct horsepower match. Avoid choosing it based only on the phrase “15 hp”; the product information does not establish universal compatibility with every 15 hp jet setup.
KUNOANZ 855721T8 Stator
The KUNOANZ 855721T8 is described as a replacement stator for Mercury 6–25 hp two-stroke outboards. Its listing recommends using the engine’s nameplate information—especially model and serial number—to find the right part.
Best for: Mercury 15 hp two-stroke owners who need a stator and have verified 855721T8 against their original component or parts information. This is a broader horsepower-range option than the 15–25 hp listing above. A broad range does not guarantee fit across engine variations, so confirm the exact application before purchase.
KUNOANZ 174-6617K1 Stator
This KUNOANZ stator is listed for Mercury 6–40 hp two-stroke engines. The product information advises checking the nameplate and detailed part information rather than relying on the engine’s year.
Best for: Buyers whose Mercury 15 hp engine’s model and serial data identify 174-6617K1 as the correct stator. It is included as a possible 15 hp match within its stated range, not as a guaranteed fit for all 15 hp jet outboards. Its listing does not specifically identify a 15 hp jet model, so verify carefully.
LINGYUE EFI Fuel Injectors
This listing is for a three-piece set of six-hole fuel injectors. It names Mercury and Mariner 15, 25, and 30 hp EFI jet four-stroke outboards and lists part numbers 8M0091784, 898101T74, and 898101T75. The product description says the injectors are intended to replace worn units and support fuel delivery.
Best for: Owners of a 15 hp EFI four-stroke jet outboard whose original injector number matches one of those listed. This is the only selected product described specifically for EFI jet applications. It is not presented as a fit for two-stroke engines; confirm the part number and engine configuration first.
Buying Guide: Choosing A 15 HP Jet Outboard Part
Is this a complete 15 hp jet outboard?
No. These listings are replacement parts: four stators and one fuel-injector set. If you need a complete motor, none of the products here fulfills that request. A jet-drive outboard’s configuration and engine details matter when selecting parts.
How do I verify stator fit?
Start with the model and serial number on the engine nameplate. Compare the original stator’s part number with the listing, then check the manufacturer’s recommended application information. The products cover overlapping horsepower ranges, but that overlap does not prove interchangeability.
Which listing is the closest match for a 15 hp engine?
The JETUNIT and KUNOANZ 174-6617A17 listings explicitly include 15 hp in their stated ranges. The 855721T8 and 174-6617K1 listings also cover horsepower ranges that include 15 hp. Choose by verified part number and engine details, not range alone.
Does the engine’s fuel type or stroke matter?
Yes. The stator listings are described for two-stroke engines, while the injector listing specifies EFI four-stroke jet applications. Match the product to the engine type and original component; do not assume a part for one configuration suits another.
What should I check before ordering?
Confirm the exact part number, engine model, serial number, horsepower, and two-stroke or four-stroke configuration. For jet applications, verify the listing’s stated jet fitment where applicable. Contact the seller or consult manufacturer parts information if any identifier differs.
Frequently Asked Questions
Are any of these products complete outboard motors?
No. They are replacement stators or EFI fuel injectors, not complete engines.
Can I choose a stator using horsepower alone?
No. The listings recommend checking the engine’s model and serial number and confirming the part number.
Which product is listed for 15 hp EFI jet engines?
The LINGYUE injector set is listed for Mercury and Mariner 15 hp EFI jet four-stroke applications, among others. Verify the injector number before ordering.
Are the stators suitable for every 15 hp jet outboard?
No universal fit is established. The stator listings describe specific Mercury or Mariner applications, and compatibility should be confirmed using engine and part identifiers.
