Mercury – Fuel Boost Pump Kit | DFI / DTS 3.0L Series | Marine-Grade Fuel Delivery | 888733T02

Overview

There’s a certain comfort in hearing your outboard settle into a strong, steady idle — that low, confident hum that tells you everything beneath the cowling is working the way it should. When you’re running a high-output two-stroke, especially one that’s spent its fair share of mornings chasing bait lines or powering through open chop, you depend on clean, consistent fuel delivery. The Mercury Marine part number 888733T02 Fuel Boost Pump Kit is one of those quiet heroes in the system. You may never see it once it’s installed, but you’ll absolutely feel the difference in how quickly your engine comes to life and how smoothly it responds when you lean into the throttle.

Performance & Practical Benefits

When a fuel boost pump starts to weaken, your engine tells you — hesitation under acceleration, inconsistent idle, or that frustrating feeling of power slipping in and out when you’re trying to make clean runs. Installing the 888733T02 brings everything back into balance. Fuel pressure stabilizes. Throttle response tightens. The whole engine feels more willing, more awake.

You’ll notice smoother cold starts, cleaner transitions between idle and mid-range power, and a steadier tone under load. That’s because the pump is doing exactly what it’s engineered to do: keep fuel moving at the pressure your outboard was built around. Whether you’re trimming up and running across the flats or throttling down to slide into a marina slip, the difference is clear.

This kit is built to survive the harshest parts of boating life — the constant vibration, the summer heat, the sudden bursts of throttle, and the long days idling through no-wake zones. Every component is made to resist corrosion, fatigue, and pressure loss over time. Installation is straightforward, and once it’s in, it’s designed to deliver consistent performance season after season.

Why Buy OEM

Fuel systems are not the place for guesswork. A genuine Mercury Marine part ensures the pump meets the exact flow and pressure specs your two-stroke needs. Aftermarket versions may look similar, but small deviations in pressure output or internal construction can lead to hard starts, detonation issues, or long-term engine wear. With OEM, everything fits right, works right, and lasts longer. It’s the advice any experienced boater would give their buddy at the dock — stick with the real thing, and you’ll avoid countless headaches later.
