Whitecap Universal Motor Flusher w/Rectangular Cups

The Whitecap Universal Motor Flusher with Rectangular Cups (Model P-2401) is a marine maintenance tool designed to protect and preserve outboard and inboard motor engines. This universal motor flusher connects directly to a water source and allows operators to flush saltwater, sediment, and debris from cooling systems without requiring a full docking procedure.

The included rectangular cups create a watertight seal around the motor's water intakes, directing freshwater through the cooling passages to remove corrosive salt deposits and particulates that accumulate during offshore operation. The universal design accommodates a wide range of engine sizes and intake configurations, making this flusher compatible with most outboard and inboard motors. Weighing just 0.85 lbs and measuring 5 x 4 x 17 inches, it stores easily on any vessel and deploys quickly between trips.

Saltwater corrosion is one of the primary causes of marine engine failure. Regular motor flushing extends engine life, improves cooling efficiency, and reduces maintenance costs. This Whitecap flusher is essential for commercial fishing operations, charter boat services, recreational anglers, and any operator running engines in brackish or saltwater environments. Fresh-water boaters benefit from seasonal flushing to remove sediment and algae buildup in cooling systems.

Whitecap has long been recognized in marine hardware for practical, user-focused engine maintenance products. The rectangular cup design provides better contact with varied intake geometries than round alternatives, ensuring consistent water flow and coverage across different engine brands and horsepower ratings.
