Note: Manufacturers of outboard motors designed with flush ports engineered some of these models differently.
The important question to ask your manufacturer is whether or not your model was engineered to flush the lower unit to include the impeller and the water pump, or only the upper part of the engine around the heads.
Since Salt-Away removes salt from all parts of the engine, it is very important to include the removal of salt from the impeller and water pump.
If your engine’s flushing path does not include the lower unit, we recommend that you flush your engine the old fashioned way – Salt-Away solution running through the flushing muffs covering the water intakes located on the lower unit, with your engine running. Please see Instructions – Using Flushing Muffs.
Important: Your engine must not be running when flushing your engine through the flush port.
