Inboard & Stern-Drive System

Inboard and stern-drive marine engines run hotter and harder – as a result accumulate corrosive build up faster.

The patented SuperFlush Systems technology designed for the unique needs of inboard and stern-drive engines, removes corrosive build up from these marine engines and systems.

Easily installs in about 1.5-2 hours.Part # SF-400C

Whether your boat is a pleasure cruiser or a working boat, SuperFlush Systems provides the added protection that keeps your engine clean and your boat sailing to the next destination.

Water from a standard garden hose connects to the easy flush valve and powers up the turbine assembly of the SF 400 unit, causing it to rotate at around 750 rpm. This creates 10000 or higher pressure pulses that blast salt and build up out of your engine. Combined with multi-port injection, this technology does what no other product can.
