Complete Water Pump Repair Kit for Mercury 20 HP Model 200 Outboards (1967-1980) | Replaces OEM 46-48744A3, 48744A3, Sierra 18-3448 | Includes Impeller, Housings, Gaskets & Base

Built to Outlast the Elements Restore your outboard's cooling system with the FASWORX Complete Water Pump Kit, engineered as a premium, built-to-last upgrade over standard OEM components. Designed specifically for Mercury Marine Model 200 (20 HP) outboards (1967–1980), this kit ensures your engine maintains optimal operating temperatures even in the most demanding saltwater and freshwater environments. Advanced Material Science We don't just replace parts; we upgrade them. Our kits utilize high-impact, temperature-resistant polymers for the upper and lower housings to eliminate warping under thermal stress. Combined with a marine-grade EPDM rubber impeller and 316 stainless steel wear plates, this complete assembly resists corrosion, dry-rot, and degradation better than standard factory replacements. Confirmed Fitment Make: Mercury Marine Model: Model 200 Engine Size: 20 HP Outboards Compatible Years: 1967, 1968, 1969, 1970, 1971, 1972, 1973, 1974, 1975, 1976, 1977, 1978, 1979, 1980 Cross Reference: Replaces Mercury 46-48744A3, 48744A3, and Sierra 18-3448.
