If the pump body, inlet\/outlet fittings, or impeller are severely corroded or damaged, those components may also need service for full restoration.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eRestores motor-driven performance when matched correctly\u003c\/li\u003e\n  \u003cli\u003eBest results when impeller and housing are in good condition\u003c\/li\u003e\n  \u003cli\u003eReplacing seals and gaskets reduces risk of leaks\u003c\/li\u003e\n  \u003cli\u003eFollow manufacturer torque and assembly guidance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: boat owners, dockside technicians, and marine service shops seeking an OEM-style replacement motor cartridge for Johnson Pump 750 GPH cartridge pumps.
