I have been told by some that seafoam realy works. I have called a few shops and they go boths way for and not for. I have never used this stuff. I have a 2 stroke 1973 evinrude 50hp on my 13 bw. What is you guys and girls thoughts on this stuff and the best way to use it and how.
I swear by this stuff. Been using it for years. At the beginning of the season I start with a "shock treatment" Maybe not best word... First time out I fill a small portable tank and add an entire can, 3 gals would work. Then run it close to dry. Toward the end of the season I add a can to my tank. One can treats 28 gals. When I first got current rig, it idled poorly, I was sure I going to need a carb rebuild. The seafoam seemed to clear it.
Good Luck

Many other boats and outboards in my boating history
The Whaler is the one I like the best!!!
I use it in everything including my diesel pickup. Cleans the jelled 2-stroke oil
out of carb bodies and jets. Got my snow thrower running trouble free again.
Have recommended to people with balky chainsaws, they come back saying wow
runs great now. Mechanic in a can.

Give this THREAD a read as I had a similar question a few months back. Jeff gives a detailed explanation of how to use the SeaFoam to really clean out an engine.
Seafoam in a spray can is called Deep Creep by Seafoam. I just decarbonized my `58 Evinrude Lark 35 yesterday. It wasn`t idling good and was loading up and dying. I always have Seafoamed all my old motors,(don`t have any other kind), and realized the Lark had never been decarbonized. I spray about 2/3 can through carb at fast idle, then slow it down and keep spraying until it dies. Then pull plugs, tilt engine all the way up and squirt a liberal amount in through the spark plug holes. Reinstall the plugs, let sit in that position overnight, All the carbon will be softened up. The Following morning run the engine and it will blow out all the carbon. The best way is to launch the boat, and blow it out and run it for an hour, but this is not always possible. It runs and idles like new now.
