Bought three of these. Works perfectly to flush saltwater out of both 454’s, and to descale the on board central A/C system. A/C kit smaller, 3/4” unit. Mounted all three on the transom above the swim platform. Installed stainless steel hose fittings instead of the supplied chrome fittings as the boat is in a wet slip in saltwater. No corrosion. All three work as expected.

Easy to install and works great for our boat on the lift where we could not get back there to flush

I purchased two of these 1-1/4" Perko adapters for my twin 6.2L Merc inboards and one 1" Perko (reduced to 3/4") for my genny. Plumbed all three into one 5/8" feed, using a single Perko water-inlet (water-hose) fitting on the aft part of my stern's gunnel plus a couple 5/8" tees and around 30' of 5/8" supply hose. Found the 5/8"-supply was enough to feed either engine at idle, but not both at the same time. Genny actually sucked twice the flow of the big engines at idle, and the 1" Perko gasped for more water than I could give it... but it worked out just fine.I've used these Perkos in three different situations now, and they performed exactly as I hoped they would:1) in dry-dock, I was able to feed both engines and genny water from a garden hose, until they were warm-enough to change the oil (probably 3-hours)2) at my dock, I was able to flush-out the brackish/salt water from my pumps and manifolds, without having to close any seacocks (something very difficult to reach on my boat)3) I used a 3/4HP submersible pump to suck antifreeze from a 5-gallon pail, with the discharge going into my Perko (garden hose) flush-fitting. I winterized both engines and my genny (plus their mufflers) in about 1-minute each, consuming a total of 6gal of antifreeze1-1/4" Perko valve: #0456DP71-1/4" Perko valve kit (has 0499000CHR water-inlet plate and fittings): #0457DP71" Perko valve: #0456DP6I could NOT be more happy with the performance of these Perkos, though a couple buddies tried to put them down because they're all-plastic. Personally, I think the plastic (if strong enough) probably has longer/smoother operation than metal parts would have (especially in salt), but makes one a little nervous without an ABYC-certification stamp... if these crack/fail, the boat is headed straight to the bottom. I tried to get more information from Perko 3-times, and they never returned my calls/emails.
