Salt Shift Marine Engine Flush Kit for Boats & PWC — Concentrated pH‑Neutral Formula, Universal Hose Flusher

Salt Shift Marine Engine Flush Kit is a concentrated, plant-based system that rapidly dissolves salt, calcium and sediment to protect outboard and PWC cooling systems.

After a day on the water, salt and mineral deposits can collect inside your engine’s cooling passages and accelerate corrosion. This kit combines a 2x concentrated, pH-neutral formula with a universal flusher attachment so you can rinse deposits away quickly and safely without harming gaskets, rubbers or the surrounding environment. It’s an Australian-made maintenance solution designed for boats, jet skis and personal watercraft.

How quickly does the Salt Shift flush work?

The formula is engineered for fast action: it begins breaking down salt and scale within seconds and finishes rinsing away deposits with a short flush. That speed reduces time on maintenance and lowers the chance of trapped salt causing corrosion during storage.

• Visible dissolution of salt and calcium within about 30 seconds
• Concentrated liquid treats multiple flushes per bottle
• Universal flusher connects to a garden hose for quick setup
• Adjustable concentration dial lets you control dilution for different engines

Is this safe for my engine’s seals and components?

Yes. The Salt Shift formula is pH-neutral and phosphate-free, formulated to be gentle on rubber, gaskets and other sensitive parts while still removing harmful mineral buildup. It also leaves a light protective barrier to help slow corrosion between uses.

• Plant-based ingredients reduce aggressive chemical exposure
• Safe for elastomers, hoses and metal cooling passages
• Non-phosphate and environmentally considerate for waterways
• Concentrated mix avoids overuse of harsh chemicals

What does the kit include and how do I use the flusher?

The kit pairs the concentrated flush liquid with a universal canister-style flusher that clips to a garden hose and attaches to your engine’s cooling inlet. The tool simplifies mixing and rinsing so you can clear deposits without complicated adapters or long drain procedures.

• Universal flusher canister with on/off switch for easy control
• Concentration adjustment dial to set mixture strength
• Connects to most outboard and PWC cooling intakes and chassis flushers
• Designed for quick, plug-and-play rinses at the dock or on shore

Will this product harm the environment or local waterways?

The Salt Shift formula is plant-based and phosphate-free to minimize environmental impact compared with harsher alternatives. While it’s formulated to be considerate of waterways, follow local regulations for runoff and avoid direct disposal into sensitive areas.

• Plant-derived ingredients reduce chemical load on water
• Phosphate-free to limit eutrophication risks
• Use recommended dilutions to minimize discharge volume
• Dispose of rinse water according to local guidelines

Who is this for: This marine engine flush kit suits boat and PWC owners who want a fast, effective way to remove salt and limescale without risking seals or using harsh chemistry. It’s ideal for weekend boaters, commercial operators, and anyone preparing engines for storage or long periods between outings, especially those who prefer Australian-made, plant-based maintenance products.
