Engineered Marine Products 46-46501 Water Pump Kit, Replaces Mercury/MerCruiser 817275A3/817275A4, Fits Alpha Gen II Outboards

The Engineered Marine Products 46-46501 Water Pump Kit is a replacement cooling system pump kit for Mercury/MerCruiser outboards and Alpha Gen II sterndrives. The kit is built around a stainless steel housing paired with a rubber coated wear plate, giving the wear surfaces corrosion resistance while the wear plate absorbs impeller contact during operation. It is engineered as a drop-in replacement for the Mercury/MerCruiser 817275A3 and 817275A4 water pump kits, and cross-references to GLM 12416 and Sierra 18-3570, so it can be ordered under whichever number is on hand.

Fitment covers Mercury/Mariner 3-cylinder outboards from 30 to 105 HP, 4-cylinder outboards from 75 to 120 HP, and V6 outboards from 200 to 250 HP, as well as MerCruiser Alpha Gen II water pumps. Engineered Marine Products manufactures replacement parts for a wide range of engine brands and supplies both OEM production and aftermarket service parts, and this kit carries a 2-year limited warranty. It weighs 1.301 pounds as packaged.
