Sierra 18-3377 Johnson/Evinrude Water Pump Kit

The impeller service kit for small Johnson and Evinrude outboards, minus the housing. Impellers are a wear item, and the vanes take a set when the motor sits, so a kit that includes the plate, key and grommet gets you a proper job instead of a new impeller spinning against a grooved old plate.

• Kit contents: 18-3002 impeller, 18-3103 impeller plate, 18-3326 impeller key, 18-3329 grommet
• Fits Johnson and Evinrude 10 (1949 to 1957), 15/18 (1953 to 1965), 20 (1966 to 1973) and 25 (1969 to 1978)
• Does not include the pump housing
• Interchanges with Johnson/Evinrude 0379773 and 0382468
• Built to meet or exceed OEM requirements

Check the housing bore for grooving while you are in there. A worn housing will chew a new impeller inside a season no matter how good the kit is.
