View Full Version : Warning about Perko Flush-Pro

One of the first things I did when I bought our 2004 X10 was install a Perko Flush-Pro so I could run the engine with the boat out of the water for maintenance etc. When I ran the boat for the first time this season last week I saw that Flush-Pro had broken completely at the seam around the circumference.

I ordered a new Flush-Pro and noticed that it's constructed differently and seems to be beefed up at that seam that broke on us. Made me think that we're not the first ones to have this issue.

Anyway a warning to those of you who have a Flush-Pro that's a few years old to keep an eye on it. I have no idea what caused ours to break. It doesn't seem to be under untoward pressure.

Thanks for the head's up. Hope everything is fine with your engine.

what year is your kit? I put one on in 6 months ago and seems to be working fine

Thanks for the heads up. I ran mine on my 1996 for three years without issue. It would have been about the same vintage as yours. Hope you did not mess your boat up to badly. Best thing to do when you over heat is to get towed in... their is no "limping" when you are overheating!

Hope your engine is alright. I was thinking about putting one of those in my boat a couple years ago, but after hearing about so many of them failing, I followed Sodar's example after reading this thread: http://www.mastercraft.com/teamtalk/showthread.php?t=20417&highlight=engine+flush
Bought everything @ Home Depot for half the price of the flush kit.

Next step for me is to be sure the engine is fine and to decide whether to hit up Perko for some kind of compensation.

Sounds like a FRIVALIOUS (sp) lawsuit is in the making here. WOW!!

Had the same thing happen to a Perko flush kit some years back on a previous boat. Never really did trust them after that.

Took the factory installed one out of our XStar and installed one of these instead:

Okay, Jim. I can't tell whether or not you're trying to be funny here, but I resent the implication. First of all, I didn't say anything about a lawsuit and my expectation is that we caught the problem quickly enough so that the only cost was a wasted afternoon and a new part.

On the other hand, if a company produced a defective part and knew it was causing potentially serious problems , but chose not to do anything about it, wouldn't you want the opportunity to seek redress? I'm making an assumption that Perko had a reason for beefing up the seam on the Flush-Pro from the one I bought in 2004, to the one I bought this week. Seems logical that they figured it was a weak point. If that's true, seems like the right thing for them to do would be to issue a recall for the ones with the weak seam.

I certainly didn't anticipate getting into an argument over the post. It was genuinely aimed at warning others in the forum that the part might have a weakness and it might be a good idea to keep an eye on it.

I read all the post about the flush-Pro prior to purchase, I think the best advice about these is not to apply a lot of hose pressure before starting the engine as this is causing them to crack. Hook up the hose, turn on slow, start engine, then increase pressure. This is the method I use, has not failed yet, fingers crossed.

Maybe I am a bit anal retentive 8p but I always check fluids, open the hatches, check the bilge etc. at every launch!:D

nothing beats the MST Guardian FLush system. You don't even have to have it running and waste 15 minutes of flushing your engine out after a salt run as well. You can still hook it up and start it if you want, but don't have to.

Thanks, Matt, for the tips. Should also help that the new version looks more robust.

Here's the comparison. The old one is the top photo. It broke right where the clear part connects to the black part to the right of the direction arrow. The seam on the new one below (opposite the direction arrow) seems reinforced.

My understanding is that later-model Malibu V-drives are using the ZF Ski-Vee v-drive unit. That thing is water cooled direct from the raw water intake before the raw water pump, like the old Walters V-drives. If I were using my boat in salt water, I'd want that V-drive flushed too, but I don't see how the MST Guardian would do that. Seems to me it would take a Flush Pro or one of those Forestar valves installed between the intake and the V-drive in order to flush that.

Note in the warranty statement for the Flush Pro that their liability is limited to replacing the unit, and it specifically states:

PERKO SHALL NOT BE LIABLE FOR LOSS OF USE OF ANY OF ITS CONSUMER PRODUCTS, NOR FOR OTHER INCIDENTAL OR CONSEQUENTIAL COSTS, EXPENSES, OR DAMAGES INCURRED BY THE ORIGINAL CONSUMER-PURCHASER OR BY ANY OTHER PERSON.

Check to see if your state statutorily excludes that limitation, but I don't think Oregon does.

Even if your engine fried as a result of the Flush Pro failure, Perko would almost certainly "compensate" you by sending you a new Flush Pro.

Correct Bigmac, the way it works is there is a hose before the v-drive, hose after the v-drive (before the impeller), after the impeller, etc....... Whenever I flushed mine with this system I bought, it would back flush through the v-drive and out the bottom. Then it would fill the risers up and blow it all out the back of the exhaust. However, so it didn't blow any seals or anything, it had a pump regulator of some sort that all the hoses plugged into. It was awesome and I could still use "Salt Away" which is a product that west marine sells. It's almost like a soap and you put it in a dispenser when you hook your hose up.

Problem with the flush pros that everyone found out in Hawaii, is that it just flushes out the bottom of the risers. The top inside of the risers would cake up with salt crystals and start rusting. The water would only flow at a limited speed from the flush pro and still cause problems in the long run unless you had aluminum jacketed risers. :)

MST still in business? Rumors are that they folded.

What about this product - supposedly by same guy...

I emailed the guy last week and just got an email back saying that they went out of business. That sucks! All because some tard that was there top guy took off with customers and the product line to start his own.

Yep, that's the one I had.

There is no need to install anything but a tee. My flush connection is a 3/4" hose connected to the lowest part of the 1-1/4" raw water hose. This floods the raw water hose and excess water flows out through bottom of the hull and the engine draws in whatever it needs. Its a very simple flush connection.

Please let me know what type of putty or compound is that bleeding over the connection of the brass fitting? thanks for your time.

Thanks for the opinion, could you please show a picture of the t connection you are talking about thanks.

An interesting idea. If the hose is on full, then any excess water will go out the thru-hull, and conceivably flush the transmission cooler at the same tlme. Once the engine is started, it will take in as much water as it needs. It seems to me that a system like this is better than Fake-A-Lake.

Where did you find the T fitting by chance? Or maybe the brass fitting to be more exact.

Yeah, even the new ones look kinda cheesy. I put one on tne new boat this fall, but I mounted it right above the rw intake on the hull. Think I'm pulling it off before running it next year.

Coz, thanks for the pics, where would you buy one of those brass top tees?

The tee in Coz's looks like its cast iron. That is a lot nicer than the thick plastic one i have. Mine is just a 1-1/4" x 1-1/4" x 3/4" schedule 80 plastic tee. The brass part shown is just a NTP pipe thread x 3/4" hose bib adapter. I extended mine with a hose so its accessed from under the rear seat of my vdrive.
