When your boat’s electrical system starts to struggle — dim lights, slow starts, or weak battery charging — it’s usually your alternator telling you it’s time for a change. The Mercury Marine 805884T Quicksilver 65-Amp Alternator gives your classic GM V8 marine engine (350, 454, or 502 EFI) the strong, steady power it was built for. Designed for 1993–1996 engines with a V-belt pulley, this alternator keeps your battery charged and your onboard systems running smoothly, whether you’re cruising at idle or throttling up across open water.

Performance & Real-World Benefits

The 805884T Quicksilver alternator gives your electrical system a clean bill of health. When the old one starts to fade, your voltage drops, batteries weaken, and onboard electronics start to act up. This OEM replacement brings your system back to life, ensuring dependable starts and steady voltage across the board.

Because it’s marine-specific, this alternator is sealed and built to handle the heat, moisture, and vibration that come with boating. It provides consistent power at low idle speeds and high RPMs alike, so your lights, instruments, and bilge pumps work exactly when you need them.

Why Choose Mercury OEM

The Quicksilver 805884T isn’t just another replacement alternator — it’s the same one Mercury installs on its factory-built engines. Aftermarket versions often can’t handle the unique challenges of marine use — high humidity, salt exposure, and constant load cycling.

Mercury’s OEM units are designed and tested for those exact conditions. Every alternator is precision-built, corrosion-protected, and thoroughly bench-tested to deliver reliable output for years of use. It’s the kind of dependability that keeps you on the water instead of at the dock.
