This outboard motor was descaled using ScaleAway BioMarine Descaling Engine Flush descaling solution.
To descale an outboard motor as above, use the following steps:
Step 1 - Fill a 200L drum with 100 litres fresh water and 25 litres ScaleAway BioMarine (125 litres of diluted descaling solution).
Step 2 - Put drum below motor and lower motor into drum to circulate the descaling solution through the motor.
Step 3 - Ensure motor is secure and propeller does not touch inside of drum.
Step 4 - Water intake must be submerged into the descaling solution by ensuring anti ventilation plate is below fluid level.
Step 5 - Run motor on idle speed for 1 hour. (Descaling time may be reduced by using a stronger solution)
Step 6 - Flush out motor with clean water once descaling has been done.
25 litres of ScaleAway BioMarine mixed with 100 litres of clean water makes 125 litres of descaler which will descale up to five small outboard boat motors.
(Depends on amount of scale build-up)
