Troubleshooting & FAQ
How do I know if this repair kit fits my engine?
Verify that your engine is a Mercury Mariner 2-stroke outboard rated from 80 HP through 125 HP and built between 1988 and 2004. Compare the original fuel-pump configuration and reference number with 1395-811287, 811287, 8M0138942, or 14687A4. Model and serial-number verification is recommended before installation.
What symptoms may indicate a fuel-pump repair is needed?
Possible symptoms include hard starting, hesitation during acceleration, unstable operation, stalling, reduced fuel delivery, or fuel leakage around the pump. These symptoms can have other causes, so inspect the complete fuel system before replacing components.
Is this a complete fuel-pump assembly?
No. This product is a repair kit for the accelerator-pump section of the fuel-pump application. The complete fuel-pump assembly and unrelated fuel-system parts are not included.
Does this product fit 4-stroke engines?
The company fitment information specifies Mercury Mariner 2-stroke outboard engines. Do not use this listing for a 4-stroke engine unless the exact original part number and fuel-pump configuration have been independently confirmed.
Can I install this kit without a service manual?
Use the correct service information for your engine. Fuel-system disassembly requires careful attention to component orientation, hose routing, sealing surfaces, and leak checks. Professional installation is recommended if you are not familiar with marine fuel-system repairs.
What is the difference between this repair kit and an OEM part?
This listing is for a replacement repair kit identified by the stated Mercury reference numbers. It is not described as a complete original-equipment fuel-pump assembly. Compare the supplied components with the original parts before installation.
How fast do you ship and what is the cost?
Shipping options, delivery estimates, and applicable costs are shown at checkout based on the destination and selected service.
What is the warranty and return policy?
Warranty coverage and return eligibility are governed by the current store policy. Contact support with your order details before returning or installing a part if you believe the item is incorrect or damaged.
