2001 Blue Run-Dry Impeller | Globe 01-12-1811

Globe 2001 Blue Run-Dry Impeller | 01-12-1811 | Brandonite | Single Flat | MerCruiser Mercury Quicksilver

The Globe #01-12-1811 is the 2001 Blue run-dry impeller manufactured from Globe's Brandonite compound — a high-strength, self-lubricating elastomeric material guaranteed to run dry for 15 minutes without damage. The 2001 Blue is the Brandonite replacement for MerCruiser, Mercury Marine, and Quicksilver raw water pump impellers, using a single flat (D-bore) drive hub with a 3/4" shaft. Includes matching gaskets and/or O-rings. Delivers up to 3x the service life of standard rubber, nitrile, or neoprene impellers. Also replaces Sierra 18-3087 and CEF 500214. Water applications only.

Additional Information

MerCruiser Raw Water Pump Application:

MerCruiser Alpha and Bravo sterndrive raw water pumps use a single flat (D-bore) shaft drive. The raw water pump is located at the front of the engine and circulates seawater through the heat exchanger to cool the closed cooling circuit. The 47-59362 series impeller (and its lettered suffixes) is the standard Mercury/MerCruiser impeller for this pump. Globe's 2001 Blue Brandonite replacement matches the Mercury OEM impeller dimensions exactly while adding the 15-minute run-dry guarantee that standard Mercury/Quicksilver rubber impellers do not offer.

Mercury Part Number Suffixes — Which One Do I Have?

Mercury and MerCruiser use letter suffixes on impeller part numbers to designate successive revisions (A1, B1, T1) of the same base part. The Globe 01-12-1811 replaces all current suffix variants of the 47-59362 series. If your parts reference shows 47-59362, 47-59362A1, 47-59362B1, or 47-59362T1, the 2001 Blue is the correct replacement regardless of the suffix letter.

Brandonite Run-Dry Technology — Why It Matters for MerCruiser Applications:

MerCruiser raw water impellers are a known weak point in the sterndrive cooling system — dry-run events occur when:

• The engine starts with air in the raw water inlet line after a period of lay-up
• The raw water pickup screen becomes clogged with debris or vegetation, momentarily interrupting raw water supply
• The boat is operated in very shallow water with the inlet near the surface

A standard Mercury rubber impeller fails rapidly in any of these conditions, sending vane debris downstream into the heat exchanger and triggering the engine's high-temperature alarm. Globe Brandonite's 15-minute run-dry rating provides a meaningful safety window in all three scenarios:

• 15-minute guaranteed run-dry rating — standard impellers fail in under 30 seconds dry
• Up to 3x service life vs. standard Mercury/Quicksilver rubber impellers under normal wet operation
• Post-dry-run serviceability — inspect after a dry-run event; if undamaged, can return to service; standard impellers must always be replaced after any dry run

Frequently Asked Questions

1. Does this impeller fit MerCruiser Alpha and Bravo raw water pumps?
The Globe 01-12-1811 replaces MerCruiser 47-59362 and its lettered variants, which are used in both Alpha and Bravo sterndrive raw water pump applications. Confirm your pump's OEM impeller part number is in the 47-59362 series before ordering. If your pump uses a different MerCruiser impeller part number, contact us at MacombMarineParts.com with your engine and outdrive model for fitment confirmation.

2. Does this impeller replace the Sierra 18-3087?
Yes — the Globe 01-12-1811 is a direct Brandonite replacement for Sierra Marine 18-3087. Both serve the same MerCruiser/Mercury raw water pump application; the Globe 2001 Blue adds run-dry capability over the standard Sierra impeller.

3. Does this impeller include gaskets and O-rings?
Yes — the Globe 01-12-1811 includes matching gaskets and/or O-rings for the pump cover. Replace all included sealing components at each service — do not reuse old gaskets or O-rings when reinstalling the pump cover.

4. What is the recommended service interval for the MerCruiser raw water impeller?
Mercury/MerCruiser recommends annual raw water impeller inspection and replacement as part of the sterndrive's annual service. Replace immediately on any sign of vane cracking, deformation, or missing vanes — or after any confirmed dry-run event. If vanes are missing on removal, flush the downstream cooling circuit (heat exchanger, thermostat, exhaust manifold water passages) before installing the replacement impeller.
