Outboard Engine Flush — 1L Outboard, Inboard & PWC Descaler | Saltworx Australia

Outboard Engine Flush — 1L
Salt buildup in the cooling system is the number-one cause of marine engine overheating. A plain fresh water flush doesn't remove it — this descaler does.
Every session in salt or brackish water leaves calcium, corrosion and carbon inside your cooling jackets and wet exhaust. Those deposits bond to the internal metal, narrow the water passages and restrict water flow. As flow drops, running temperatures climb — overheating, faster anode wear, and hardened seals follow. It all happens where you can't see it: inside the block.
A plain freshwater flush pushes loose salt through, but does nothing to deposits that have already bonded to the metal. The Saltworx Marine Engine Flush is a purpose-built descaler that dissolves that buildup, then leaves a corrosion-inhibiting layer behind on the internal surfaces for ongoing protection between flushes.

Testimonials
"My mechanic the 100 hour service and went to change the anodes in the motor, he pulled them out and made a comment “what ever you are doing, keep it up”. He put the original anodes back in as they looked brand new after 100 hours. Very happy with this engine flush. It has already saved me money on replacing the anodes."
