Remove Salt from Outboard & Inboard Motors

Fresh water flushing is ineffective in removing salt calcification and corrosion. Salt deposits inside your motor's cooling system cause damage in three ways:

1. Salt calcification builds up on the surfaces of the cooling corridors. This salt build-up creates an insulating layer which reduces the efficiency of the cooling system. The result is the temperature rises and eventually your motor starts overheating.
2. Salt eats into the alloy or steel, burrowing into the engine block to eventually eat throgh into the cylinders, crankcase or the outside. This corrosion is out of sight and costly!
3. The salt deposits build up and block narrow cooling corridors. This causes 'hot spots' in the motor which can cause piston 'grab' and seizure, resulting in an engine rebuild.

Salt can get into unseen locations and totally destroy major components, split bearing housings from the inside or totally eat through castings. The first sign is blistering on the outside and the full consequences of the damage only become apparent when it's too late.

Salt-X SX50 can prevent all of this!
SX50 given time, can even turn back the clock!!

How to Remove Salt Corrosion & Deposits

For Outboard & sterndrives the Auto-Mix Injector is the easiest system. To use the Auto-Mix Injector:

1. Install the Auto-Mix Injector into your fresh water flush hose, making sure water flow is in the direction of the arrow. 
2. Start the water flow and the motor, bring to running temperature. This allows the thermostat to open and the system to work fully (this is not required for direct powerhead water flush connection)
3. With the motor running, unscrew and remove the clear bowl from the Auto-Mix Injector, dump the water and add the recommended amount of SX50 for your motor. Refit the bowl containing the SX50 concentrate. 
4. Water will fill the bowl and the solution then runs into your motor. Allow to flush for the pre-determined time, then turn off the motor and water immediately. 
5. Do not flush the SX50 out of the cooling system! 

For Inboard motors that draw their cooling water from the sea via a skin fitting in the hull, a T piece with valve needs to be inserted between the sea cock and the motor's sea water pump. This will allow you to introduce SX50 into the cooling system, be it direct into the engine block or into a heat exchanger.

No Fresh Water? No Problems!

SX50 can still be used if you do not have fresh water! SX50 can neutralize salt water and turn it into a flushing solution! All you have to do is increase the concentration to 1 part SX50 - 20 parts Salt water!
