Installation Guide

  1. Preparation: Disconnect the battery and relieve fuel system pressure before beginning installation. Ensure the work area is well-ventilated and free from ignition sources.
  2. Access: Remove engine cowling and locate the existing fuel pump assembly on your outboard motor. Take photos of hose connections for reference.
  3. Disconnect Fuel Lines: Carefully disconnect fuel inlet and outlet hoses from the old pump. Have a container ready to catch any residual fuel.
  4. Remove Electrical Connections: Unplug the electrical connector from the old fuel pump. Label wires if necessary for correct reinstallation.
  5. Remove Old Pump: Unbolt the mounting hardware securing the fuel pump to the engine block. Remove the old pump assembly.
  6. Install New Pump: Position the new fuel pump assembly in place and secure with original or new mounting bolts. Tighten to manufacturer specifications.
  7. Connect Fuel Lines: Attach fuel inlet and outlet hoses to the new pump, ensuring correct orientation. Use the provided cable ties to secure connections firmly.
  8. Reconnect Electrical: Plug the electrical connector into the new fuel pump, ensuring a secure and proper fit.
  9. Inspection: Double-check all connections, hose clamps, and mounting bolts for tightness. Verify hose routing matches original configuration.
  10. Prime System: Reconnect the battery and turn the ignition key to prime the fuel system without starting the engine. Check for fuel leaks at all connections.
  11. Test Run: Start the engine and allow it to idle for several minutes. Monitor for smooth operation and verify no fuel leaks are present.
  12. Final Check: Reinstall engine cowling and perform a brief on-water test to confirm proper fuel delivery and engine performance.

Troubleshooting & FAQ

Q: How do I confirm this fuel pump fits my specific Mercury engine?
A: Cross-reference your engine's model, horsepower, and cylinder count with the compatibility table above. Verify your original pump's part number matches one of the listed OEM numbers (8M0118177, 899106T01, 892874T01, etc.). Also confirm the hose connector configuration matches your current pump.

Q: What are the signs that my fuel pump needs replacement?
A: Common symptoms include difficulty starting the engine, loss of power at high RPM, engine surging or stalling, rough idling, or hearing unusual whining/buzzing noises from the pump. If you notice fuel leaks or the pump fails to prime, immediate replacement is recommended.

Q: How often should I replace the fuel pump on my outboard?
A: Fuel pumps typically last 3–5 years or 300–500 hours of operation, depending on fuel quality and usage conditions. Inspect the pump annually and replace if you notice performance issues or visible wear.

Q: Will this aftermarket pump perform the same as the original Mercury part?
A: Yes, this replacement is manufactured to meet OEM specifications for fit, pressure output, and flow rate. It uses comparable materials and is designed to deliver reliable performance equivalent to the original part.

Q: Do I need any special tools to install this fuel pump?
A: Basic hand tools are sufficient—socket set, screwdrivers, and pliers. You may need a fuel line disconnect tool depending on your engine's hose fittings. Always have a fuel-safe container and rags on hand.

Stylish looks, good lenses, warped frame?
Color: Dark Tort/Green, Polarization Type: Non-Polarized, Lens Width: 50 Millimeters
These sunglasses have nice build quality and good lenses on them. The green tint is not too strong and the style is excellent. My frames sit crooked on my face out of the box and they do not lay evenly on the counter when laying them down on the top surface. you can tap on one of the arms and the frames wobble. Looking at the main piece where the lenses are, the whole thing appears to be slightly twisted., which would explain the crooked fit on my face. Granted, our faces and ears aren't usually perfectly symmetrical, but this seems to be a fault of the sunglasses. I have tried lightly bending and twisting the frames to straighten them out, but I have not been entirely successful in doing so in fear of breaking them. They are comfortable to wear and look pretty stylish, but some information on adjusting the frames would be nice.

Sleek and stylish
Color: Dark Tort/Green, Polarization Type: Non-Polarized, Lens Width: 50 Millimeters, Color: Dark Tort/Green, Polarization Type: Non-Polarized, Lens Width: 50 Millimeters
Sleek and stylish sunglasses in a dark tortoise pattern. Simple classic design. Unisex design and fit. I especially like the wired sides that are easy and safe to customized to your head, ear, nose fit and comfort. Seems like a good value for quality, design, comfort and fit. Comes with a slim case. Nice sunglasses overall!

Sturdy & well made & they stay in place!
Color: Dark Tort/Green, Polarization Type: Non-Polarized, Lens Width: 50 Millimeters, Color: Dark Tort/Green, Polarization Type: Non-Polarized, Lens Width: 50 Millimeters
Wow, these are really nice & well made sunglasses!! I love them better than my prescription sunglasses that I paid a ton for that I really don't need when I am out in the sun. They have some weight to them and don't feel like cheap sunglasses you get off the rack in a drugstore and they fit comfortably on my face and nose. The build-in nose pads hold them in place so they don't slip down my nose!! They come packaged with care in a nice carrying case and there's a lens-cloth included in the package. The price on these won't break the bank and I'm really glad to have found them as I do spend a lot of time in the sun or bright light.

Soft case, not universal, not worth the price
Color: Dark Tort/Green, Polarization Type: Non-Polarized, Lens Width: 50 Millimeters, Color: Dark Tort/Green, Polarization Type: Non-Polarized, Lens Width: 50 Millimeters
I didn't pay for these, but priced at more than $70, I wanted to try them. The description is confusing if not misleading, stating "Quay merges music and fashion to create trend-forward designer eyewear for any moment or mood." Given the exorbitant price for a brand I never heard of (e.g., Raybans may be overpriced, but they come with a 24 month warranty and it's a brand that's been around a long time), I thought that these shades played music. How else are ordinary $10 sunglasses priced at nearly $100? How do they "merge music"??? Answer: they don't. They're sunglasses. They're also not "Designed for a universal fit," because they're way too big for me, and I have a normal-sized head, and I have bought many pairs of sunglasses and nearly all of them fit just fine. In fact, this is only the second time I ever tried on a pair and they were too large, but the other time, those sunglasses, which were a lot more stylish than these, cost around $20. The case is soft, which is ok, I guess. Some people prefer it but to me, if a case will not provide any protection from being crushed, e.g., sat upon, or had something heavy put on top, then it's not a very good case. They also included a nice lens cloth.

Impressive lenses quality for polarizing that works
Color: Matte Black/Black Polarizedarized, Polarization Type: Polarized, Lens Width: 50 Millimeters, Color: Matte Black/Black Polarizedarized, Polarization Type: Polarized, Lens Width: 50 Millimeters
As much quality of polarized glasses that you can get for the value here with actively polarizing glasses that not only block bright sunlight but dramatically reduces glare and bright rays on light surfaces even compared to some "better" sunglasses that aren't polarized. You really have to test them yourself to see, and if you like the lenses, you'll like this! The lenses are dark grey, so they keep the true color of grass, trees, sky, everything, just with dimming effects which I prefer, it's not a massive change changing colors, it's more natural to me. The quality & style is high with the whole glasses feeling sturdy and smooth as you open them and put them on. It's made with some basic plastic frames, they have a nice softer texture that's almost silicone feeling, so they feel great & soft but also it helps support sitting on the nose and ears. Perfect fit (I'm a man, average head I would say lol) I haven't noticed any sliding around at all with these! Lenses are made from PC with polarizing. They feel thick, sturdy, and stay clean. I have only noticed one fingerprint so far after wearing them for 2 weeks. It definitely is a weekender look and case build. The edges sit a little further away from the skin so depending on the angle there can be a little glare and reflections of your eyes cheeks in the lenses. If I had to choose a part I don't like the most that would be it. Pretty glarey on the inside. On the outside, it's reflective to any light so lots of sunlight will reflect off and hide your eyes which I like. Aesthetics, usability, quality for the value, all make this stand out to me and I would definitely be packing this when I'll be in a lot of light, even for driving with the anti-reflection polarized lenses. Very impressed with this pair. I would like the sides to be closer but I guess I would have to get a different style, these are weekender, so all in all I'm a big fan!
