Does anyone have any experience with this product? It supposedly back-flushes the engine, & you don't have to run the engine while you flush. I saw them mount this system on an outboard on Ship Shape TV, but I'm curious if it's really worth the money.

Dunno how this works, but my Evinrude has a
place to attach a hose at the back of the block,
and the manual says you don't need to run it.
I'm sure my neighbors appreciate it.

HOWEVER: it also says don't exceed 50 PSI so
don't turn the hose on full blast. The static
pressure at Pt. Lobos is about 150 PSI, and I
suspect that's how I got water in my lower unit
oil last year. Now it's 1 turn on the hose
bib max.

Looks like they want $230 for it. The claim is that it uses "pulse" technology to create high pressure blasts that knock the salt loose. Another benefit is that you can mount the hose fitting in a convenient place so it's easy to flush (without wrestling with rabbit ears).

Here's the link:

I was just curious if anyone has any long-term experience with it.

Salt is water soluble. If it hasn't dried out,
it's flushed in 60 seconds. If it has dried out,
maybe 5 minutes. It shouldn't get a chance to
dry out.

High pressure pulses shouldn't be necessary, and
could push water past the seals.

Run...Don't walk away from that Guardian setup. The I/O ones will fill your cylinders with water on more than one occasion(bad thing). The outboard one is ridiculously expensive. Earmuffs are $4 and a muffler(if that is a problem) is $40. I assume I am on the same page with Stve where I welded a rod ty earmuffs so you can just lean against the transom and slide them on and off easily. Most modern outbaords have flush systems already installed. For I/o's Perko makes agreat system that hooks to your raw water line and blocks off the seawaterflow when switched on. Can't do any harm from there. The guardian is more intricate and can backfill if thermostat is closed etc.
