Mercury – 100 Hour Maintenance Kit | MerCruiser 4.5L V6 & 6.2L V8 | Complete Service Components | 8M0147052

Overview

There’s a certain ease you feel when you know your engine is taken care of — the kind that settles in when you turn the key and your MerCruiser lights off with that smooth, confident rumble. That peace of mind doesn’t come by accident. It comes from staying on top of routine care, especially the 100-hour service that keeps everything running tight, clean, and ready for the next stretch of water. The Mercury 8M0147052 100 Hour Maintenance Kit puts all the essentials for that service in one place, making the job simple and worry-free.

Instead of piecing together filters and seals or hoping the parts you grabbed actually match your engine, this kit delivers every component built exactly to Mercury’s own specifications. It’s clean, reliable, and built for boaters who’d rather spend weekends cruising, fishing, or pulling kids on tubes — not hunting down mismatched parts.

Performance & Practical Benefits

Using this kit is really about giving your engine the best chance to perform at its peak season after season. The included oil filter maintains a steady, clean flow even during high-load operation, while the fuel filter helps your engine breathe freely and respond smoothly when you ask for power. The gearcase drain seals add extra security to one of your engine’s most vulnerable systems, helping to keep water where it belongs — outside the case.

After performing your maintenance with this kit, you’ll likely notice a smoother idle, cleaner acceleration, and a sense of confidence that your engine is protected from the inside out. Every part fits perfectly, threads cleanly, and performs exactly as intended because each one is engineered by the same people who built your engine.

Why Buy OEM

When it comes to engine maintenance, shortcuts tend to show up later — usually at the worst possible time. Mercury OEM parts are designed specifically for your MerCruiser engine, offering dependable filtration, superior corrosion resistance, and precise fitment that aftermarket parts rarely match.

You’re not just buying components — you’re buying longevity, efficiency, and the reassurance that your engine is protected by the same standards Mercury uses on the production line. It’s practical, it’s cost-effective, and it keeps your engine ready for whatever the season brings.
