TESTIMONIALS FROM HAPPY CUSTOMERS! From: Nicky@______ Sent: Tuesday, October 07, 2003 6:00 PM To: dbrogdon@mstguardian.com Subject: happy customer I purchased a system in the beginning of this season. My boat is new with only 1 season without your product. I installed it myself witch took about less than 2 hrs. I am very happy with your product and tell people about it all the time, I actually show it off at the marina. I was wondering if you could give me some tips on maybe using the flush clear, how often, etc Any tips on any of your products would be good. I have a 5.0 MerCruiser. I/O. I recently winterized it, and It was so simple to just connect a pump to the inlet of the mst line. Thanks mstGuardian!!!
Why I Use an mstGuardian System, By John Wiesgerber Hi, my name is John Wiesgerber from Tampa, Florida. Last year (1998), after 4 years of running my boat with no problems, I decided to do some preventive maintenance by removing and replacing the elbows and risers from my engine's exhaust system as specified in the engine maintenance manual. I took my boat to the dealer I'd used for years. Later that day I received a phone call from the head mechanic and he asked, "Why do you want to replace the elbows and risers, they are like new?" I was totally amazed. Then I remembered, I was using an mstGuardian unit that I had purchased 4 years earlier to clean my engine as recommended by the company. I was so amazed and happy that I called the company to let them know what had happened to me and to let them know how happy I was that I was using an mstGuardian unit. Besides, they had just saved me over $1500 in parts and labor. Thanks to the mstGuardian, my exhaust system is still running strong with many years of usage still ahead. Economic impact? You bet! I've saved over $1500 with my purchase of an mstGuardian engine cleaning system, by not having to replace my exhaust system parts. As a matter of fact, it looks like I might even double the life of the elbows and risers. Thanks Marine Science Technologies.
Glen Connelly Interview 7 May 1999 4425 Bay wood Dr. Panama City, FL
When did you first buy a Flushmaster? “I saw an article in the newspaper about this invention on the beach and I said, I've got to have one of those!” “My son use to have to wade out in the canal to put earmuffs on the motor and he would tell me crabs were biting his toes and everything. But that was his job and that was a mess trying to do that every time we came in. So I saw this thing and thought this looks like a great idea!” “I can't remember how I made contact with Flushmaster but I remember this guy named Jerry. He came out and put it on. When he looked at the engine he said I'm going to have to mount it on the transom cause there's no room under the cowling. So he put it in and its worked great.” “It has really saved a lot of time and effort on our part. I can just hook it up and leave the water running and not have to worry about it. Of course when you're running an engine you're going to have to sit there and wait for it. It's very inconvenient with the old system especially when I keep the boat in the water as much as I do. This is a 1991, 225 HP engine with 600 hours and I put the Flushmaster on in 93. I've never had any problems with the engine since I put on the Flushmaster. To me the convenience is the reason and I can't measure the lack of engine wear or whatever other than the fact I have not had any engine problems with this motor in saltwater and its never been in freshwater. The tilt mechanism is the only thing that's ever been fixed or replaced. As far as Flushmaster in concerned, I'd buy one again in a heartbeat for my next motor whether or not I kept it in or out of the water. The convenience of not having to run the engine and all that would be enough for me. I'd highly recommend it for anyone. I'm very happy to support Flushmaster.” Glen Connelly is an avid fisherman and retired Air Force Fighter Pilot living in Panama City, Florida. He has years of experience in boating in saltwater. He has his Flushmaster on a 22 foot Sports craft with a 225 HP Suzuki.

John Tippanaro of Seaford, NY 11783
… said" Even though I am not very mechanical, my son and I were easily able to install the MST Guardian system on our Mercury outboard. The directions were easily understandable, and all the components are obviously of very high quality.” He then requested 100 brochures to pass out in their fishing club.
Casablanca owner’s comment The owner of an 84-foot Hatteras, the Casablanca, in Palm Beach, said he bought the mstGuardian systems for his diesel engines (and generator & 4 air conditioners) primarily because he wanted to eliminate the black soot that gathers on his transom (as well as recover his lost fuel economy and range)! He was so pleased with the result he then had them installed on his 45-foot Cigarette boat for corrosion and overheating protection.
"Yermo M. Lamers" John, The guardian unit made winterizing my boat extremely easy. I was the envy of the marina. The final install turned out really well. "Yermo M. Lamers" NO PROBLEMS WITH ENGINE RUST? Right? … Right? … WRONG! So you flush your engine whenever you use it? - Me too. So you’re not worried about rust because you flush it out all the time! – I’m not worried either … that is until yesterday (July 21, 1999). I bought my runabout, with a 5.7-Liter Mercury, and immediately installed a special Tee fitting to easily flush the engine which is much better than “ear muffs” because all the water is forced into the engine. This boat was used just over 4 hours a month for a total of only 246.5 hours. It had been flushed with fresh water EVERY TIME! … So, I was not worried. After joining MST, we decided to use my boat for a test and yesterday we removed the exhaust elbows – and right then I stopped smiling! What a mess! One of the 1/2-inch thick solid cast iron sections had rusted through and broke off in our hands when we removed the rubber hose! If we had hit a good hard wake, the whole exhaust pipe could have broken free while we were underway!
Look at how much the opening for the water flow is clogged up! The parts “downstream” from here were just starting to show the heat
You can see where the salt water was just starting to work its way into the engine. A few more hours and it would have been history. If you have more than 200 hours on your engine and don’t have an mstGuardian installed (that you use EVERY time) – then I strongly suggest you pull the elbows off and check it out RIGHT NOW! Believe me, you don’t even want to think about the cost of a new engine! If you operate the boat in salt water – inboard or outboard – you need to either place the entire inlet of the out drive in a drum of fresh water and run the engine for 15 minutes -- or install an mstGuardian, and use it. If you don’t do one of those two things – it’s only a matter of time! And if you miss the guess on the time – you ruined a new engine. I was lucky. I now have an mstGuardian on my boat!
John W Darrah
“… the Guardian paid for itself many times over. Navesink River … during a new moon and extremely low tide…pulled sand up into the engine… was idling - the boat was overheating. Sand in the engine block, and throughout the cooling system was the problem. I attached the dock hose to the Guardian and turned it on. I let it flush the engine for a good 20 minutes that day and the next. When I started it the next day it ran fine. To fix the problem w/o the Guardian would have caused me to pull the engine and would have costs $1500-$2000. Based on that experience I will install the MST Guardian in every boat I will own and the proof is I order another Guardian system for the next boat I just bought.”
John Sklinar, Navesink River
I have had 15 boats and have never had anything like this. My mechanic says the inside of my Volvo 5.7 liter is like brand new! Even the gaskets look like new. My mechanic says we should convince Volvo to use our system since it is far better. I recommend it. John Lania, East Hartford
ABOUT EXHAUST MANIFOLDS
Exhaust manifolds last forever, don't they? Even if they do fail, it isn't a major problem, right? These are common reactions when people are asked about their boat's manifold. Unfortunately, exhaust manifolds are important, and ignoring them can lead to expensive problems, perhaps an engine rebuild. There is an additional hassle—manifolds are normally damaged by corrosion, so they're not covered by your insurance policy. Rather than seeing it as a "sealed for life" component, view a manifold as a service item to be replaced at regular intervals. If you do this, major problems can be avoided.
Life Expectancy
How long will a manifold last? Obviously the way you use your boat will be a factor, as will the type of water it's on. Saltwater boats are going to have a much shorter manifold life when compared to their freshwater counterparts. Most experts suggest that a manifold will have a life expectancy of six to eight years. However, heavy use in southern saltwater environments can see this drop to as low as three years while lightly used freshwater boats up north can get up to 20 years out of a manifold. One thing is for certain, the older your manifold gets, the more likely it is to fail. This is clearly shown in the chart below.
Probability of Failure

Why So Fragile?
The manifold is a complex metal casting, actually a pipe within a pipe. It feeds hot exhaust gases and water to the riser where the gases and water combine to continue their trip overboard. Without the cooling effect of the water, the hot gas would burn through a hose or thin wall pipe very quickly.
Keeping the water and gases separate in the manifold is critical. If water finds its way into the gas-only section, it can enter the engine cylinders and wreak havoc with the internal engine parts.
Manifolds and risers live in an incredibly harsh environment. They endure very hot corrosive gases slamming into the manifold at high velocity. The water jacket portion of a manifold is intermittently exposed to hot saltwater and moist air, the perfect conditions for corrosion. All the time they're vibrating madly during running time and left idle for long periods, allowing rust to eat away at the metal. That they last as long as they do is impressive.
Symptoms
Before your manifold fails, you may get warning signals. Needless to say, you should take notice immediately. If your engine is difficult to start, produces white smoke, or runs roughly, water in the cylinders may be the culprit. If you ignore the situation, hydro lock may occur. This is when water has leaked into the cylinder, making compression impossible. Massive, usually terminal damage will result as you try to start the engine.
Inspection is always a good idea, and we recommend that you try to do so at least every few years as the manifold nears its expected life span. It's impossible to see into all the passages, but you will still get some clues about the extent of corrosion. Your manifold may be blocked with the products of corrosion, for example, leading to "hot spots" in the cooling system and low-level overheating. These won't necessarily show up on your temperature gauge, but can result in a shortened engine life.
Rust stains dripping from the riser seams may indicate water is leaking inside, too. This warrants removal and checking for corrosion and the gaskets.
White crust around the gaskets is indicative of Salt Creep – which is a clear indicator of a partial failure of the gasket.
Note - the above corrosion damage will happen the engine even if is flushed every time with the traditional earmuff flushing system and running the engine for more than 20 minutes each time. The only effective method we know to deal with the problem is the mstGuardian flushing system using a patented hydrostatic water pulse system to remove the salt effectively. Some mechanics have reported the exhaust system looked like brand-new even after 5 years operation in salt-water.
Manifold Replacement
If you planned ahead and used an effective flushing system you won’t need this advice, but if not … well, replacing a manifold is certainly a job that you can do yourself. It may take longer than you expect, though. Bolts may be rusted in place and other fittings may be in your way. If this doesn't appeal to you, hire a mechanic.
Pull a riser off and check. If your manifolds and risers are not already rusted too badly you should be able to avoid the further damage with an effective flushing system. Or if you decide that your manifolds and risers are nearing the end of their service and you don't want to interrupt the boating season with a blown engine, replacements are available from many West Marine or Boat US Marine Center. You will need the make, model, and serial number of the engine, the exhaust pipe diameter, and will need to order the necessary gasket kit, installation kit, and end plates if required.
A final word of warning: each year, owners (and mechanics) sink boats by leaving the exhaust ports unplugged after disconnecting the manifolds. Waves sloshing into the ports can sink a boat overnight. Hoses must be plugged and tied securely above the waterline to prevent water from flowing into the boat. With this in mind, consideration for your manifold will pay dividends in reliability and peace of mind, giving you seasons of trouble-free service.
