Marine Growth Buster, 1 Gallon Concentrate

I had an Evenrude 70 hp outboard overheating. Took off the lower unit and dropped an old bilge pump in the bottom of a 5 gal. bucket. Poured in the gallon and ran it statically thru the motor for about a half an hour. The scum in the bottom of the bucket told me that this stuff removed the clogged port. And it did. Motor runs cold to normal even at full throttle. I will be buying it again for sure!

This product does exactly what it claims.I have 2 cylinder volvo diesel marine engine and after just one use, the cooling lines and and water jackets were completely cleaned out. The water flow was increased and the engine now runs cooler.Very happy with the result

It does work! It helps to remove barnacle and corrosion build up. But if you have thick rust layer in cooling system I suggest to use evaparust coolant rust remover and let it set in cooling system. Once rust is mostly removed then use baranacle buster to flush system and you will be shocked of all the rust corrosion and barnacles to flush out the system. I will be using it once a year on boat. Just using baranacle buster I brought the boy motor temp down 12-15degrees helps with making system flow.

I don’t know how it performs compared to other brands but 2 of our 3 AC units on our boat we’re getting High Pressure errors and shutting off after running for a while. We flushed everything thoroughly according to directions and voila! Problem fixed in both units.

I’ve been using this for years to keep the engine’s cooling system on my boat clean of salt and calcium scale. I strongly recommend using this to keep your engines running at their best.

This product used along with circulation system made by same company. Great for all raw Salt Water heat exchangers. Used on two Cummins Diesel engines, Kolher Gen Set, three Cruse Air A/C systems and one Freezer. Plenty of U Tube info on how to use this product.

It works. Saw a lot of brown junk flushed out of the heat exchangers. I dropped it a star because it is rather inconvenient to pull off hoses, impellers and buy all the fittings and pump to make it work. Gets a little messy too due the needing a water hose and leaks. Beats pulling the engine apart.

have a boat with twin diesel engines second bottle of use of this to clean heat exchangers works great saved a lot of money doing it myself versus hiring mechanic
