It draws raw water through the engine's cooling circuit to keep operating temperatures in check, and because it is bi-directional it can be installed without regard to engine rotation direction, simplifying the swap for installers working on different GM-based inboard and sterndrive setups. The pump ships with the correct mounting gasket (18-0981) already included, so there is no need to source a separate gasket kit before installation. Its housing has a machined exterior finish for a precise fit against the engine block and consistent sealing surface. At 12 x 6 x 6 inches and 10.727 pounds, it matches the dimensional footprint of the OEM circulating pump it replaces, allowing for a direct swap using existing mounting hardware and coolant lines. This pump is cross-referenced to several OEM and aftermarket circulating pump numbers, making it a straightforward replacement for GM V-6 and small block V-8 engines that use one of those original part numbers. Whether you are restoring an aging cooling system or replacing a pump that has started to leak or seize, this unit is manufactured to provide reliable, consistent water circulation for GM V-6 and small block V-8 marine applications.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Engineered Marine
