Yes, and quite well.<br /><br />It's one of those products that actually does what it claims. :D

Re: seafoam?

i personally like this procedure:

Decarb, take a can of seafoam put 3/4 of it in the gas tank, with only 1 gallon of premixed gas. put the rest in a spray bottle. start the engine, and let it come up to temperature. then remove plugs, and them some real good shot of seafoam into the cylinders, replace plugs, let sit 15 minutes. restart, and spray the rest of the seafoam into the carbs, so the the motor almost stalls, wait and repeat until the seafoam is gone.then take for a wide open spin. then put in new plugs, ad premixed gas to the tank, and take it for a wide open throttle spin. it is going to smoke like a house on fire, during this process.

afterwards compression.recheck

Re: seafoam?

When would you suggest to de-carb brand new engine for the first time ?
Roughly after how many hours carbon could be a problem ?

Re: seafoam?

Run it in the fuel and you do not have to decarb every 50 - 100 hours plus it does a great job of keeping the fuel system clean. When you change plugs, or if you are just curious, pull the plugs and look into the cylinder with a pen light. If you see carbon build up, then do a decarb. No sense giving your engine an enema if it isn't constipated!!!!!!!!!!!!

Re: seafoam?

I second Silvertip's suggestion. I add Seafoam to every tank of fuel, according to the instructions on the can. Keeps the internals of the outboard clean.

Re: seafoam?

Read the label. If you have an older boat and the fuel system has not been very well taken care of, run a full can in 15 gallons for a tank or two. Then cut it in half.

Re: seafoam?

I found it in my local NAPA store, they started stocking it about 2 years ago in my neck of the woods. Should be in your local stores as well.
