Salt-Attack Direct Injection Kit For Marine Cooling Systems

Designed for vessels that live in salt air and salty seas, the Salt-Attack Direct Injection Kit (SADI) keeps your marine cooling system clean, protected, and ready for extended time on the mooring. This direct-injection solution is engineered to work with both open and closed circuit saltwater cooling systems, delivering a precise 50/50 mix of Salt-Attack concentrate and fresh water to flush and safeguard engine cooling paths you rely on every voyage.

Why this kit stands out

What sets the Salt-Attack Direct Injection Kit apart is its practical, all-in-one design tailored for boats with inboard/outboard stern drives. It provides a straightforward, plug-and-play installation that doesn’t require specialized tools or repeated trips to a marina. The result is a cleaner cooling circuit, reduced salt buildup, and better long-term protection against corrosion and costly motor issues in marine environments.

Key features and what they mean for you

• 12V or 24V compatibility—works with the common marine electrical systems you already have on board, simplifying installation and power supply planning.
• Ready-to-install package—includes wiring, tubing, rocker on/off switch, and quick-connect fittings, so you’re not hunting for individual components.
• Direct-connection fittings—standard 1/4 BSP quick-connect fittings with 6 mm tubing and 5 meters of high-pressure tubing to connect the reservoir to the water strainer or water pump.
• All-in-one reservoir setup—one reservoir channel simplifies maintenance and keeps your 50/50 Salt-Attack concentrate ready for mixing with fresh water.
• Easy dosing and routine—once installed, maintain the mix and flush your engine for 20–30 seconds after every mooring session to keep salt deposits at bay.
• Included concentrate—standard kit comes with 1 liter of Salt-Attack concentrate, designed to form a protective barrier inside the cooling circuit after flushing.

How it works in everyday use

After installation, you top up the reservoir with a 50/50 Salt-Attack concentrate and fresh water mix. When you’re done on the water, simply run a brief 20–30 second flush to rinse the salt and mineral buildup from the cooling path. This simple routine helps preserve the performance of your engine, reduces maintenance time, and can extend the life of critical cooling components on boats that spend long periods moored in saltwater.

Who will benefit most

Ideal for boat owners with moored vessels, inboard/outboard stern drives, and any watercraft relying on saltwater cooling systems. If you want a maintenance-friendly, install-anywhere solution that minimizes salt-related wear without disrupting existing systems, Salt-Attack SADI is designed for you.

Real-world benefits and outcomes

• Lower maintenance costs over the life of your engine due to fewer salt-related issues in the cooling circuit.
• Quicker, more convenient flush routines that fit into regular boating habits—especially after long periods on the moor.
• Improved reliability of open and closed loop saltwater cooling systems through consistent salt removal and protection.

What’s included and how to get started

The Salt-Attack Direct Injection Kit arrives with a manual switch suitable for wiring to the helm area and a 1 L Salt-Attack concentrate. It’s ready to install and pair with your existing water system, ensuring you can start protecting your engine from day one.

Technical snapshot

Part Number: SADI. Compatible with 12V or 24V electrical systems. Includes 1/4 BSP quick-connect fittings, 6 mm tubing, and 5 meters of high-pressure tubing to connect the reservoir to the water strainer or water pump. Designed specifically for marine cooling systems on moored vessels with inboard/outboard stern drives.

How to maximize value

To keep the cooling system performing at its best in saltwater conditions, follow a simple care routine: keep the reservoir topped with the 50/50 mixture, perform a 20–30 second flush after each day on the water, and periodically inspect the quick-connect fittings and tubing for wear. The result is less downtime, fewer expensive repairs, and more confidence when you head back out to sea.

Warranty and trust

Salt-Attack brings years of ocean-grade marine care expertise to your boat’s cooling system. This Direct Injection Kit reflects that knowledge, delivering a reliable, purpose-built solution for protecting your investment on the water.
