Has anyone ever used this system ?

They are out of business. Do you already have the system? I've been looking for a few parts on the system I have but cant locate them cause the company went belly up.

My buddy has two brand new never used units for 500EFI's sitting here......he's gonna be selling his boat soon and i dont think he's gonna install them.....does any one have any interest in them? I can ask him what he wants for them.....

The system works great.......I thought someone bought the company?

I've been trying to get a few parts for mine. Bought a new boat recently and had kept them from my old one. Unfortunately when they were removed some of the platic fittings for the cooler and block were broken. I've tried for a while to get replacements but have gotten no response from MST or Blue ocean where I originally bought them. The company had some kind of legal issues and I guess theft of the original idea or name but from their website it says they are no longer offereing the product. If your buddy winds up not selling the whole systems I'd buy the fittings if they were correct. I think I need three or four.

I thought I saw the Guardian stuff on Dollar's website. Did you contact them?

Sure Wally ask your buddy the details of them..always thought about adding one of those systems.
Thanks.

I am interested in the MST Guardian system and I am sorry they are out of business, but I have found an alternative I think:

http://www.superflushsales.com

It seems to be the same concept as the MST Guardian system, anybody that has puchased from http://www.superflushsales.com ? It is unclear whether the price includes all fittings etc.

looks like same people to me ..... I remember the same pics of before and after ........ fine print at bottom of website

*SuperFlush is also referred to as: super flush, motor flusher, QYSA, QYSA SuperFlush, QYSA super flush, marine motor flusher, outboard motor flusher, boat motor flusher, io engine flushing, marine engine flushing kit, and it replaces Johnson outboard motor flusher, evinrude 225 engine flushing, yamaha flusher outboard, Guardian, Perko, MST Guardian, ThoroFlush, MACS, Flush-Pro

Found another web site with the same type of product http://www.qualityyachtservicesofamerica.com/
and it also links to http://www.superflushsales.com/

Probably the same product as MST Guardian. Just strange that the other web sites are up and running and no information that the company is closed. I actually tried calling the 800 number, but since I am calling from Denmark I had to listen 3 times (1 time in French and 2 times in English) that I have to accept the charges since I am an international caller, and then I got an invalid dial tone when it was supposed to start ringing. I assume it means that the number no longer exists.
