Performance & Practical Benefits

A fuel pump may be tucked out of sight, but you feel its importance every time you advance the throttle. With the 8M0058164, the fuel delivery feels smooth and steady — no hesitation, no surging, just clean and consistent flow. That translates directly to confident hole shots, predictable acceleration, and a comfortable cruising rhythm.

The pump’s design mirrors the original equipment exactly, eliminating guesswork and offering a tight, proper fit. You’ll appreciate how secure everything feels once bolted into place, especially when you’re navigating chop or running long stretches. Corrosion-resistant materials and a sealed bowl orientation help protect against wear, moisture, and debris — all the things that tend to creep into a marine engine bay over time. Maintenance stays simple: clear access, clean lines, and a part built with longevity at its core.

Why Buy OEM

When it comes to fuel delivery on a V8 marine engine, there’s no room for experiments. Aftermarket pumps might look similar, but small differences in pressure, valve timing, or internal materials can lead to hard starts, vapor lock, or premature failure. A genuine Mercury Marine part is engineered specifically for your MerCruiser system and calibrated to operate exactly as the engine expects.

Choosing part number 8M0058164 means you’re installing reliability, protecting engine life, and avoiding repeat repairs — the kind of practical choice any seasoned boater would recommend.
