Water Pump Kit for Johnson Evinrude OMC 20 25 30 35 HP Outboard Boat Motor Parts
When your outboard's cooling system starts pushing weak telltale water, the water pump impeller is usually the first suspect. The decision for many boaters is whether to replace just the impeller or buy a full rebuild kit with all the gaskets and seals in one box. For Johnson, Evinrude, OMC, and BRP two-stroke engines in the 20-35 HP range, this Candy Marine kit packages the main water pump components at a listed price of $19.99.
Quick verdict: This kit gives you the impeller, housing, wear plate, seals, gaskets, and mounting hardware in a single package. It's a complete-looking service set rather than a bare impeller, which can simplify the repair process.
Who it suits: The kit is intended for 20-35 HP two-cycle cross-flow engines with thru-prop exhaust and one-piece gear cases. The compatibility list includes 20 HP from 1985 and up, 25 HP from 1985 and up (plus 25 HP Commercial models from 1980-1982), 30 HP two-cycle from 1983 and up, and 35 HP models from 1980-1982 or 1983 and up for two-cycle versions. If your engine falls into one of those categories, this kit is built for it.
What stands out: The kit includes a Candy Marine neoprene impeller, an impeller key, gasket, wear plate, pump cup, pump housing, grommets, O-rings, seal, and installation bolts with washers. That means less hunting for individual parts when you're mid-repair. It also lists several OEM reference numbers-393630, 0393630, 395289, 393632, and 328755-plus the Sierra cross-reference 18-3382. Those extra part numbers can be useful when confirming fit against your engine's service parts.
Meaningful trade-offs: This kit is not a universal fit. It targets cross-flow engines with thru-prop exhaust and one-piece gear cases, and the year-by-year breakdown matters. A 20 HP built before 1985 or a 35 HP model with a different gearcase configuration would fall outside the listed applications. Another trade-off: because the kit is packed with several gaskets and O-rings, you'll still want to check that the included sealing parts match the exact gasket layout for your engine block.
Bottom line: For a Johnson/Evinrude/OMC 20-35 HP outboard, this Candy Marine water pump kit bundles the core components and hardware you'd need for a water pump service at a clearly listed $19.99 price. It's a practical option when you want to rebuild the pump rather than just swap an impeller.
