Marine Growth Buster, 1 Gallon Concentrate

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

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 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!

I flushed out three AC systems using barnacle buster concentrate and dilution of one to 3.I can't really speak to how well a descaled the inside of the ac unit, since I really can't see in there without disassembling. Not disassembling is kind of the point. I can say that it did not clear out algae deposits inside the strainers,

You have to keep an eye on this stuff, but most immediately when cleaning my A/C system on board a friend's boat, the chemical recirculation bucket turned nasty and was removing crud from 8 years of inside of the cooling lines of our on boardA/C sytem. We didnt discharge it into the environment, but collected it in a 5 gallon bucket and noticed at least an inch ofcrap on the bottom that the solution had removed over an hours time of running through the cooling lines. IT WORKED! GOODSTUFF!

It did ok, but can not handle the tough stuff.

Likes; money and time saver.

Excellent product I used it to clean out my cooling system on my 90 horsepower Yamaha outboard this stuff worked great.
