Marine Descaling Engine Flush for Boat Motors
ScaleAway Bio-Marine is described as being a green descaler because of its ecological advantages.
Your boat motor is the heartbeat of your time on the water. Don't let hidden marine growth choke it to death.
Beneath your engine cowl, a silent battle is raging. Saltwater, calcium deposits, and aggressive bio-fouling—like barnacles and mussels—are creeping into your engine’s cooling jackets. They restrict water flow, force your motor to run dangerously hot, and threaten to destroy your water pump.
Meet ScaleAway BioMarine Descaling Engine Flush—the premier, eco-friendly breakthrough engineered specifically to reclaim your engine’s power, protect its internal metals, and guarantee peace of mind on the open sea.
Hard on Marine Growth, Gentle on Your Motor
Traditional descalers can eat away at your engine's delicate internal components. ScaleAway BioMarine Descaling Engine Flush changes the game with a smart, multi-organic acid formulation that targets the problem with surgical precision:
The Barnacle Barrier: It relentlessly attacks the calcium carbonate shells and tough protein threads of barnacles and invasive mussels,
breaking them down into a flushable sludge.
100% Metal Safe: This advanced formula is specifically engineered to bind only with calcium.
It frees trapped minerals without oxidizing, corroding, or attacking steel, copper, or aluminium boat engines.
Safe for Essential Rubber: It wipes out the scale without harming your vital engine seals, gaskets, or rubber impellers.
The Eco-Friendly "Green Descaler"
You love the ocean—so protect it. ScaleAway BioMarine Descaling Engine Flush delivers commercial-grade cleaning power in a fully biodegradable, non-toxic, and low-pH formulation. It provides a massive ecological advantage, ensuring you can maintain elite vessel performance without harming marine life or leaving a toxic footprint.
From Jet Boats to Mega Yachts
Whether you are maintaining a recreational weekend outboard, operating a hardworking commercial fleet, or servicing a luxury superyacht, ScaleAway BioMarine Descaling Engine Flush is the ultimate choice for heat exchangers, condensers, and all exposed water-circulation systems.
Give your motor the deep breath it deserves. Clear the passages, lower your running temperatures, and extend your engine's life.
Elite Maintenance Made Simple
Achieving a pristine cooling system is simple with our highly concentrated formula, mixed at a cost-effective 5:1 ratio (e.g., 10 Litres of ScaleAway BioMarine Descaling Engine Flush to 50 Litres of fresh water):
Prepare ➔ Remove thermostat & zinc anodes. Submerge intake in a 5:1 mix.
Circulate ➔ Run engine for 10–20 mins. Let soak for 6–12 hours to dissolve.
Neutralize ➔ Add ScaleAway pH-Buffer to reach a safe, neutral 7.0–8.0 pH.
Flush & Protect ➔ Flush with fresh water. For storage, buffer to pH 10–11 to seal.
(Always wear goggles, gloves, and a respirator mask during use to stay safe while you work with chemical products).

Achieve Peak Engine Performance in 5 Simple Steps
The Golden Ratio: Always mix 1 part ScaleAway BioMarine Descaling Engine Flush with 5 parts fresh water (e.g., 10L concentrate to 50L water).
CRITICAL PRE-FLUSH CHECKLIST
Remove Thermostat: Ensures the fluid circulates immediately through the entire block without waiting for the engine to warm up.
Remove Zinc Anodes: Internal sacrificial anodes will rapidly consume and waste the chemical strength of the descaler.
Safety First: Wear goggles, gloves, and a respirator mask. Avoid spills near grass or plants.
THE 5-STEP ENGINE REVIVAL
Step 1: Prep the Rig
Remove the boat from the water. For safety, remove the propeller. Place the outboard in a container until the engine intake is completely submerged
in your 5:1 diluted mixture.
Step 2: Circulate & Soak
Start the motor and let it run for 10 to 20 minutes to distribute the mix deep into the cooling lines.
Turn off the engine and let it soak for 6 to 12 hours to aggressively dissolve marine growth.
Step 3: Recirculate
Fire up the engine for another 10 minutes to break loose the degraded shell fragments, limescale, and bio-fouling.
Step 4: Neutralize (pH 7.0 – 8.0)
Add ScaleAway pH-Buffer directly to your spent solution bucket while running the engine
until the mixture reads a neutral 7.0 to 8.0 pH. Thoroughly flush the engine block with clean, fresh water.
Step 5: Winterise / Storage Protection (pH 10.0 – 11.0)
If packing the boat away, add a little extra ScaleAway pH-Buffer to reach a 10.0 to 11.0 pH level during your final fresh water flush.
This leaves a protective, anti-corrosive residual layer on all internal water passages.
The specialized formula in ScaleAway BioMarine Descaling Engine Flush is highly effective at dissolving calcium carbonate incrustations like zebra mussels and barnacles. The first active ingredient
penetrates organic tissue and binds tightly to calcium, while the second active ingredient in the formulation acts as an excellent chelating agent to break down and lift the dissolved shell
remnants without eating away at your motor's internal metals.
ScaleAway BioMarine Descaling Engine Flush is a low pH combination of organic biodegradable acids to dissolve the calcium carbonate shells and the proteinaceous threads holding the mussels to a surface.
ScaleAway BioMarine Descaling Engine Flush is a rapid, biologically corrosive physical destruction process dissolving barnacles and zebra mussel shells which are composed primarily of calcium carbonate.
When ScaleAway BioMarine Descaling Engine Flush hits the shell, a rapid chemical reaction occurs which dissolves the calcium carbonate, weakening the exoskeleton and breaking down the byssal threads they use to anchor themselves.
As the shell structure degrades and dissolves, the seal fails. The ScaleAway BioMarine Descaling Engine Flush descaling agent penetrates the interior, resulting in rapid mortality.
