Moeller Universal Rectangular Cup Motor Flusher 099077-00 for Side Water Inlet Lower Units

The Moeller Universal Rectangular Cup Motor Flusher (part number 099077-00) is a rectangular-cup motor flusher designed for flushing lower units that have side water inlets, including Volvo SX lower units. Its rectangular cup design improves water flow to the inlet compared to a round cup, and the dual water feed helps the cup seal tightly against the lower unit housing, virtually eliminating water leakage even during higher-pressure flushing. This makes it especially effective in low-pressure conditions often found in marinas, where a poor seal can otherwise starve the engine of flushing water.

The flusher is built in black plastic and mounts over the lower unit's side water inlets to run fresh water through the engine's cooling system while the boat is out of the water, helping to clear salt, sand, and debris that would otherwise accumulate in the cooling passages. It is a straightforward attach-and-run accessory that does not require tools to install.
