Always verify your current motor's frame (48Y) and flange type (Square Flange) before purchasing.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eQ: Does this motor come with a replacement pump seal kit?\u003c\/b\u003e \u003cb\u003eA:\u003c\/b\u003e No, this listing is for the replacement motor only. We highly recommend purchasing a new, pump-specific shaft seal kit (e.g., a WhisperFlo seal kit) whenever replacing a pool motor. Installing a new shaft seal prevents leaks and protects your new motor's bearings from water damage.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eQ: Is the Century HSQ165 wired for 115V or 230V?\u003c\/b\u003e \u003cb\u003eA:\u003c\/b\u003e The HSQ165 is a dual-voltage motor, meaning it can be wired for either 115V or 230V depending on your equipment pad's electrical setup.
