ScaleAway BioMarine Descaling Engine Flush is used at a 5:1 solution as the recommended solution strength for descaling aluminium outboard boat motors.
       Example: 10 Litres of ScaleAway BioMarine to 50 Litres of water.

Description
ScaleAway BioMarine Descaling Engine Flush is designed to safely and quickly remove scale, calcium deposits, corrosion and bio-fouling from your engine’s cooling system. These deposits can make your engine run hot by restricting water flow through the cooling jackets. Calcium build-up may also damage your engine’s water pump. Descaling Engine Flush will NOT damage seals, gaskets or rubber impellers.

ScaleAway BioMarine is fortified with a biocide to aid in the removal of barnacles and zebra mussels from the cooling system of marine vessels.

The chlorhexadine biocide used in ScaleAway BioMarine is extensively used in the dairy industry and has proven to be gentle yet effective in controlling microorganisms which contribute to bio-fouling.

Metal Safe Descaler
ScaleAway BioMarine is designed to bind with calcium molecules found in limescale. Scale build-up is the number one reason water cooled system malfunction. By binding only with calcium, remaining minerals and deposits held by the calcium are released to rinse free without harm to equipment. ScaleAway BioMarine does not oxidize, corrode or attack metals found in water systems, When used as directed, ScaleAway BioMarine Descaling Engine Flush may be used on all types of vessels including workboats, cruise ships, mega yachts, freighters, ferries and recreational boats. ScaleAway BioMarine is ideal for heat exchangers, condensers, cooling systems, and all water circulation systems exposed to water scale and bio-fouling.

Descaling Instructions for Outboard Motors
1. Remove boat from water. Ensure propeller does not hit inside of container. For safety, remove propeller befor starting the motor. Place the motor in an appropriate container so that the engine intake is well below the lip of the container.
Mix one part of concentrated ScaleAway BioMarine with 5 parts fresh water. Fill container until engine intake is completely submerged in the diluted ScaleAway BioMarine Descaling Engine Flush mixture.

2. With the engine intakes completely submerged, run engine until engine reaches normal operating temperature and thermostat opens so that the descaling mixture comes out of the exhaust/water outlet of your engine. Alternatively you can remove the thermostat form the motor to ensure descaling chemicals circulate immediately.

3. Dispose of flush mixture in compliance with local laws. Fill container with fresh water and completely submerge engine intakes in water. Start engine once more and run for 5 minutes while fresh water runs throughout the engine system.

Remember to replace your thermostat If you removed it prior to descaling.

CAUTION: Wear goggles, respirator mask and gloves when handling this acid based product. Take precautions against spills near any grass and plants.
Keep away from children and pets. Do not mix with other chemicals.
