Engine flush has been available since the 50's (and probably before that) specifically for the deed so why use vinegar?

Do you think you're out-smarting the system? You can more or less depend on a tried and proven product and I belive it's not expensive.

But as Pgitug points out vinegar has many uses. We use apple cider vinegar (and two other things) to get rid of black mould on the cap rail. Chris has a formula that includes ACV. Don't know of a commercial product that works as well. When the commercial products failed I mixed our own oil finish for the cap rails in Alaska. It worked ... ok. Got us by in the very wet weather.

settled on purchasing the concentrated barnacle buster. Mixed one gallon with four gallons water and flushed half the mix through each engine. Let it sit for 20 minutes and then flushed fresh water through. In about a minute the water was clear. Very simple...very effective. I have a fresh water flush valve mounted on my intake hose between the thru-hull seacock and water strainer which I use a garden hose connection to flush my engines after each use. I simply stuck a short hose in to the 5 gallon bucket mixture and let the engine suck it in. Make sure you use a hard walled garden hose or it will collapse from the pressure.
