I Have Heard Some Real Good Reports On This Stuff. I Bought A Can Of It For My Boat. Not Put It In Yet. I Run A 1999 Yamaha Vmax 3.1 Fuel Injected. Was Using Ring Free But It Is 16 Dollars A Bottle At The Closest Dealer To Me. The Sea Foam Says It Is Oxygen Sensor Safe And Removes Carbon Deposits. Any Feedback Will Be Helpful.
Yea that Ring Free is getting in my pocket book too....
I've never used Ring Free before, but I don't have a Yamaha outboard either. I do have a Yamaha jet-ski that I've run Sea-Foam through, as well as my truck, bass boat, duck boat, pontoon boat, and four-wheeler. I use it for everything! It's awesome!!! With all of my toys, I have very little time to do any carburetor cleaning or rebuilds, so I do all I can to keep my fuel system clean, and Sea-Foam does the trick! I've been using that stuff for ten years!
Sea Foam is good stuff, alot of people use it in outboards. I beleive that the reccommended usage of the sea foam is more than that of the Ring free, so check and see but they may work out to be about the same price. That is the ring free treats more gallons of gas per bottle than the sea foam.
Also I have read on other boards about the Yam OX sensors and they are pretty sensitive and expensive. Check around maybe someone can confirm that it is ok with the Yamaha engines but I think it should be.
Thanks For The Replies, It Is Going In The Tanks Tomorrow. Not To Sound Like A Tightwaud But The Ring Free Is 16$ And The Seafoam Is 5.88 At Advanced Auto, I Know Thats Only About 10$ But Thats 3 Gallons Of Gas That I Can Put In My Boat Or Truck
Use Seafoam at the rate of One Ounce of seafoam per Gallon of gasoline.
I am using seafoam now and started using it in every gas powered device that I own. Chain saws, Weed trimmers, Gas Blowers, Lawn mower, Truck and Boat engine.
Right now I have been using it in my 6 gallon external tank of gas for my boat motor. My boat motor is a 1978 long 35 HP Johnson Outboard Motor.
I have this brown oily substance coming out of the exhaust port inside my Prop. I guess that's the oily carbon buildup that's being dissolved by the sea foam in the gasoline. I checked my lower unit and it's not getting any water in the gear grease, so that's not causing the light brown oily stuff. It must be coming from the dissolved carbon coming out of the engine.
I also use some stabile in my 6 gallon gas tank as the gas was from last Fall.

Have used the sea foam for several years. I use it in evrything that runs on fuel. At work we run quite a few different pices of equipment, up to $70,000.00 dollar mowers, and use it to keep all running clean. This is also what i run through my gas in the fall to keep all in good shape if I'm not planning on fishing thruogh the winter. Put it in, run enough to make sure you got some throughout the fuel system, and you're winterized.
Sea Foam can also be used in concentrated form to decarb a motor. I pulled the following off another site. I've done it and it does work.
A Simple and Cost Effective Way to De-Carbon an Outboard By Capt. Bob Dunkelberger [email][email protected][/email] This works for Carbed, EFI, Ficht, HPDI, Opti-max and even 4-strokes... and should be administered after every 50-60 hours of use.
First you need a separate small fuel tank. One of those 3-gallon red Tempos works well or an empty gallon milk jug in a pinch, but it might be a bit messier. I use Seafoam over the OEM (original equipment manufacturer) stuff like OMC Engine Tuner or Mercury Power Tune. Note: in the last few years they changed the formula and you have to let them sit up 12 hours. Who's got time for that? Seafoam does the job in 15 minutes and can be purchased from NAPA, Car Quest or other auto stores.
You'll need 3/4 gallon of gasoline and one 16oz can of Seafoam for each engine. Don't forget to add 3oz of oil if you are pre-mixing in a carbed engine. Use a 3 ft piece of fuel hose off the small tank. Connect this tank to your engine by pulling off the main tank fuel hose from the intake side of your water separating fuel filter and plug the hose off the small tank onto that fitting. Or you can separate the fuel line on the tank side primer ball, so you can still use your primer. If your engine has a fuel plug then you will also need a fuel plug on the smaller tank's hose.
Start the engine, let it warm up and start pulling the mix into the engine. You may have to increase the idle to keep it running once she gets loaded with the Seafoam. Run the engine 15 minutes at the dock or just cruising around under 2500 rpm's. Then shut it down and let it sit for another 15 minutes. Restart the engine; the smoke you see is the carbon burning off. Do the whole thing again and let her sit again for 15 more minutes. If she smokes after the second time do it again. I've never seen one still smoke after three doses. (I bought a Bronco two years ago that had 95,000 miles on it. When I used Seafoam on it I had the neighbors hanging out of their front doors looking for where the fire was after I started it the first time there so much smoke) The gallon mix should be just enough to do this 3 times.
You don't need a wide-open throttle and you don't need to change the plugs. The plugs are cleaned at the same time as the combustion chambers. My suggestion is that every 50-60hrs is the optimal time to change plugs in most engines. I cleaned an antique Evinrude once that had a 1/4" of solid carbon on the exhaust chamber walls by running a 1/2 gal of the aforementioned mix through it. Seafoam, a great product, has been around since the 1930's and it's what they used when they were burning straight 4 stroke 40SAE oils in outboards.
For you guys with the 4 stroke outboards? Those engines work 10 times as hard as any auto engine ever will and they too will carbon up. Too many are under the assumption that it's totally the 2 stroke oil that causes the carbon, Wrong... it's also the additives they put in the fuels today. The carbon inhibitors in 2-stroke oil are there for this reason also. Remember when gasoline used to smell like gasoline, today it smells more like bad cologne.
For those guys that like to work the carbon treatment by spraying it down the carbs, Seafoam also comes in spray can called Deep Creep. It's the same stuff under pressure and notes on the can, "Oxygen Sensor Safe". After that, if your engine manufacturer recommends a daily additive treatment then do so. The tank and hose are a one-time purchase and the Seafoam is only costs $5-6.00 per can.
Good write up mate! Excellent!
Sea Foam is basically just NAPHTHA or a very light petroleum distillate. The number of carbon chains in the gasoline formula varies but it's numerous. So there is always a lot of unburned carbon atoms left after the combustion process, especially when there is insufficient oxygen to combine with the carbon atoms. Like all low air fires it smokes a lot. That smoke is the extra carbon going up in the air or out the exhaust port.
Naphtha dissolved the excess carbon buildup.
Naphtha sound familiar? What about Napalm? Or how about Moth Balls?
You ever hear of putting moth balls in the gas tank to give you extra performance? What do you think adding Sea Foam to the tank does? Same thing maybe? That's what I think, but I could be wrong.
Check out the MSDS Material Safety Data Sheet on the Sea Foam Product or ask the man behind the counter to see the MSDS pages on this product. They have to show it to you by law. If they say you have to call or write to the manufacture then tell them they are full of it and that if they don't show it to you right now, you will call OSHA! That normally will bring out the manager. Tell the Manager to call the owner and have them hire a safety expert to get them up to date with the OSHA regulations. LOL This will definitely get you some strange looks. Most people are clueless as to the OSHA regulations and most could care less. That's why we have more and more dangerous chemicals in the hands of people that are clueless to what their dangers are. Oh well. That's life in America. :(
