A failing fuel pump can create frustrating outboard problems, but replacing one is not simply a matter of matching horsepower.
The JLM Marine fuel pump reviewed here is an aftermarket mechanical fuel pump assembly intended for specific Yamaha 75, 80, 90, 100 and 115 HP four-stroke outboards.
It cross-references several Yamaha part numbers, including 68V-24410-00-00, 6D8-24410-00-00 and 6D8-24410-10-00.
At the time of this review, JLM Marine lists this particular version at $50.90 and includes the pump, O-ring and hose-clamping components.
That makes it an interesting replacement option for an older compatible Yamaha outboard—but exact fitment, diagnosis and installation matter much more than the relatively low purchase price.
Let's take a closer look.
Review note: Blog60s has not conducted hands-on fuel-pressure, fuel-flow, material, leak, corrosion or long-term durability testing of this pump. This review is based on current manufacturer specifications, compatibility information and the supplied product images. Manufacturer performance and quality statements should not be interpreted as independent Blog60s test results.
JLM Marine Yamaha Fuel Pump Overview
The product is supplied as a complete fuel pump assembly rather than a rebuild kit for the original pump.
The images show a compact assembly combining black polymer sections, metal components and two brass-colored hose fittings.
JLM identifies it as a mechanical fuel pump designed as a direct replacement for specified original applications.
The package also includes an O-ring and hose-clamping components required for installation.
For owners of an older compatible Yamaha four-stroke, the attraction is straightforward: instead of rebuilding an aging pump, the complete assembly can be replaced.
However, that only makes sense after confirming both the fault and the correct part number.
Key Specifications
Here is a quick overview of the product based on JLM Marine's current listing:
| Specification | Details |

The specifications above describe the JLM Marine aftermarket product and should not be interpreted as independent performance measurements.
What's Included?
In addition to the fuel pump itself, the supplied images show an O-ring and two black cable-tie-style hose clamps.
JLM's current product information identifies the package contents as:
- 1 fuel pump assembly
- 1 O-ring
- Hose-clamping components
JLM specifically references 93210-29198-00 for the O-ring and 90465-10098-00 among the related clamp hardware on its current listing.
Including a fresh seal is useful because reusing an aged sealing component can introduce another potential leak point during installation.
As always, verify the exact contents of the package received before beginning the repair.
Fuel Pump Construction
The side view gives us a better look at the construction of the pump.
The assembly combines a black molded section with a metal body and brass-colored hose fittings.
JLM describes the housing construction as plastic with metal components.
The pump is designed for use with gasoline and operates mechanically rather than being marketed as a standalone electric fuel pump.
That distinction is important when diagnosing the fuel system.
This product should not be treated as a universal external electric pump or installed simply because an engine appears to have a fuel-delivery problem.
It is intended to replace a specific pump used in compatible engine applications.
Mounting Points and Pump Design
This view clearly shows the mounting points around the pump body.
It also provides a good look at the central metal section and the two fuel fittings positioned on opposite sides.
Because the assembly is intended as a direct replacement, the mounting arrangement and connections need to correspond to the original application.
This is another reason why visual similarity alone is not enough to confirm fitment.
Two fuel pumps can look nearly identical while using different specifications or applications.
Use the engine model and OEM part number rather than appearance as your primary compatibility check.
Fuel Line Connections
The opposite side provides a clear view of the metal housing and two brass-colored barbed hose connections.
These fittings are intended for fuel-line connections secured appropriately during installation.
Fuel-system work requires more caution than many routine maintenance tasks.
A connection that appears secure but leaks under operating conditions can create a serious fire hazard.
Any fuel lines removed during replacement should therefore be inspected for deterioration, cracking or other damage rather than automatically being reused.
Connections should also be checked carefully for leaks after installation.
Yamaha Part Number Cross-Reference
The main Yamaha OEM number associated with this JLM Marine pump is:
68V-24410-00-00
JLM also lists:
6D8-24410-00-00
and:
6D8-24410-10-00
as compatible replacement references for relevant applications.
JLM has multiple related listings for pumps in this family, and some listings also cross-reference compatible Mercury/Mariner applications.
For this review, however, our focus is the Yamaha application.
The important takeaway is simple:
Do not buy the pump based only on "75–115 HP."
Match the exact engine application and OEM part number first.
Which Yamaha Engines Does It Fit?
JLM's current listing covers a range of Yamaha four-stroke engines, including applications from the F75, F80, F90, F100, F115 and LF115 families.
Examples listed by JLM include:
| Family | Horsepower | Example Years Listed |
|---|---|---|
| F75 | 75 HP | 2003–2004 |
| F80 | 80 HP | 2002–2007 |
| F90 | 90 HP | 2003–2006 |
| F100 | 100 HP | Various applications in the 2000s |
| F115 | 115 HP | Applications through 2011 |
| LF115 | 115 HP | Various 2000s applications |
These are examples rather than a universal fitment rule. JLM's detailed compatibility table contains individual model codes and years.
This matters because the model year alone may not be sufficient either.
The safest purchasing sequence is:
Engine model → production information → OEM part number → replacement pump.
If your existing pump or parts catalog specifies one of the cross-referenced Yamaha numbers, you have a much stronger basis for determining compatibility.
What Does a Mechanical Fuel Pump Do?
A fuel pump's basic job is to move fuel through the engine's fuel-delivery system at the required conditions.
Without proper fuel delivery, the engine may not receive the fuel it needs to start and run correctly.
That does not, however, mean that every starting, hesitation or power problem points to a bad fuel pump.
Similar symptoms can originate elsewhere in the fuel system or engine.
Filters, fuel lines, connections, contaminated fuel and other engine systems can all affect operation.
For that reason, diagnosis should come before parts replacement.
Replacing a pump based solely on symptoms can turn a relatively inexpensive repair into unnecessary parts swapping.
Possible Signs of a Fuel-Delivery Problem
Fuel-delivery problems can potentially appear as:
- Difficulty starting
- Engine hesitation
- Poor running under load
- Intermittent fuel starvation
- Loss of performance
- Stalling
These symptoms are not a diagnosis of fuel-pump failure.
They simply indicate that fuel delivery may be one area requiring inspection.
Proper troubleshooting should determine whether the pump is actually responsible before it is replaced.
Installation Considerations
Replacing this pump requires working directly with the gasoline fuel system.
That deserves particular attention to safety.
The engine should be off and cool, and the battery should be disconnected according to the appropriate service procedure.
Work should take place in a properly ventilated area away from flames, sparks and ignition sources.
Residual gasoline may remain in fuel lines even when the engine is not running.
Use appropriate precautions when disconnecting them.
JLM's own installation guidance likewise emphasizes battery disconnection, ventilation, a cool engine and appropriate fire precautions.
Don't Guess Fuel-Line Routing
Before removing the original pump, identify the correct hose routing and connections.
Taking reference photos before disassembly can be useful.
Do not assume that the two visually similar brass fittings can be connected interchangeably.
Follow the service information for the exact engine.
The replacement O-ring must also be installed correctly, and mounting surfaces should be inspected and cleaned as required.
After installation, check the complete area carefully for fuel leakage before returning the engine to normal operation.
If you are uncertain about fuel-system work, a qualified marine technician is the safer choice.
Aftermarket vs Yamaha OEM
This JLM Marine pump is an aftermarket replacement, not a genuine Yamaha OEM fuel pump.
That distinction should be clear before purchasing.
JLM markets the assembly as an OEM-style/direct replacement and states that it is produced to OEM-level quality standards.
Those are manufacturer statements.
Blog60s has not independently verified dimensional tolerances, internal materials, fuel-flow performance or service life against a genuine Yamaha pump.
Owners who specifically require genuine Yamaha components should therefore purchase the appropriate OEM part.
For buyers comfortable with aftermarket marine components, the JLM pump provides another replacement option at a relatively accessible price.
What We Like About the JLM Marine Fuel Pump
The most attractive feature is that this is a complete pump assembly.
There is no need to disassemble the existing pump and attempt an internal rebuild if complete replacement is the preferred repair.
The inclusion of an O-ring and installation hardware is also useful.
Another positive is the extensive part-number and model information JLM provides.
Rather than advertising the pump only as "fits Yamaha 75–115 HP," its current product page lists individual model applications and OEM references.
That makes compatibility research considerably easier.
Potential Drawbacks
The biggest consideration is that it remains an aftermarket component.
Without independent long-term testing, we cannot say whether its durability matches, exceeds or falls short of the genuine Yamaha equivalent.
Compatibility also requires attention.
The broad 75–115 HP description covers multiple engine families and production years, so the headline alone should never be used as the fitment check.
Finally, fuel-system replacement is less forgiving than many cosmetic or non-fuel repairs.
Incorrect hose routing, damaged fuel lines or a leaking connection can create safety risks.
Should You Replace the Pump Based on Symptoms Alone?
No.
This is particularly important for a fuel-system component.
Starting problems, hesitation and poor running can have multiple causes.
A replacement fuel pump should ideally be installed because diagnosis indicates that the existing pump is defective—not simply because the replacement part is inexpensive.
A correct diagnosis also gives you a better chance of fixing the problem on the first attempt.
Is the JLM Marine Yamaha 75–115 HP Fuel Pump Worth Considering?
For an engine that genuinely requires one of the listed Yamaha pump numbers, the product presents a straightforward aftermarket replacement option.
At $50.90 at the time of this review, it includes the pump assembly plus sealing and clamping components.
Its strongest points are the complete assembly, relatively modest purchase price and detailed cross-reference information.
Its main uncertainties concern the areas we cannot establish from a product listing alone: long-term durability, internal tolerances and real-world performance compared with a genuine Yamaha pump.
For that reason, we would view it primarily as an aftermarket replacement option for owners who have already confirmed the original pump is faulty and verified exact compatibility.
