Blu Thru Boat Engine Salt Flush Kit

Proudly made at our Chesterfield headquarters, the Blu Thru Boat Engine Salt Flush Complete with Mixer offers a safe, fast, and efficient solution for improving marine engine cooling performance. This kit is designed to remove salt residue, reduce corrosion, and protect internal engine components, making it an essential piece of kit for inboards, outboards, and jet skis.

The non-toxic, biodegradable formula is gentle on seals and gaskets while lubricating and safeguarding critical parts. Using the included inline mixer ensures the solution is distributed evenly throughout the cooling system, neutralising salt deposits before they can cause internal damage.

Using the Mixer with Boatworld Outboard Motor Flusher

For the most effective maintenance routine, we recommend using the Blu Thru Boat Engine Salt Flush Complete with Mixer in conjunction with the Boatworld Outboard Motor Flusher. By connecting the mixer directly to these dual-feed muffs, you ensure a consistent flow of treated water through both sides of the engine intake. This combination is particularly effective for larger outboards, ensuring the salt-neutralising solution reaches the top of the cooling galleries and clears the "tell-tale" for a strong, healthy water stream.

Versatile Marine Care

The Blu Thru Boat Engine Salt Flush Complete with Mixer doubles as a total clean, no-scrub system for all your marine gear. The mixer unit makes it easy to wash down boats, jet skis, trailers, fishing equipment, and even seaside furniture. It is a highly efficient, water-conserving system that completes a full flush in under five minutes.

Looking to Upgrade Your Engine?

While Blu Thru keeps your current motor in peak condition, did you know that we stock a comprehensive range of outboards to suit every type of inflatable and small craft if you are looking to upgrade? For those who prefer traditional power, we stock petrol outboards from Tohatsu, Honda, and Orca. We also offer a wide selection of electric outboards for a quieter, cleaner experience, featuring industry-leading technology from ePropulsion, Blade, Momentum, and Remigo.

What Our Customers Say

"This really does work. Water was just a dribble coming from the tell-tale on my outboard, and I was thinking of changing the impeller. I used the Blu Thru Boat Engine Salt Flush Complete with Mixer, and within seconds it started pumping water like a garden hose... highly recommend." Mr L.S.

"I flush my engine after every use. Blu Thru keeps my engine cooling clear and gives me peace of mind that I'm not getting any salt building up inside. It's great stuff for the price to avoid high-cost engine repairs." Garreth

"It's a great product to wash your boat, rods, and reels down with; it does a super job. I can see it removes the salt from my reels, so it is definitely removing the deposits from inside my engine." Greg H.
