Hey boat owners! If your Jabsco pump is acting up, this major repair kit has everything you need to get it running smoothly again. It's specifically designed for Jabsco pumps 1673-1001 and 1673-7001, and it'll also work with the 1673-1051 model - though fair warning, it'll convert that one to a full cam pump and boost your water flow. The kit includes all the essential replacement parts: impeller (1210-0001), O-ring, end cover, six cover screws, lip seal, slinger, cam, cam screw, two bearings, key, and two retaining rings. The impeller measures 1-1/4 inches wide with a 2-1/4 inch diameter and features 12 neoprene blades that handle water flow like a champ. The 5/8 inch shaft with 12-spline drive ensures everything fits and functions perfectly. These are aftermarket parts, but they're built to match OEM specifications, so you're getting quality without the dealership price tag. Whether you're dealing with reduced water pressure, leaking seals, or worn bearings, this comprehensive kit will have your pump performing like new. Installation is straightforward if you're handy with tools, and you'll save a bundle compared to buying a whole new pump. Perfect for marine mechanics and DIY boat owners who want to keep their cooling systems in top shape without breaking the bank.
