View Full Version : Gas tank additive

Im sure I could find 30 pages on additives however.....I have a yamaha outboard 200 and I want to run some type of an engine clean through the tank. Something to the effect of Sea Foam or something else. My question is what do you guys recommend??
Next to Sea Foam I would use Chevron Techron. This stuff is great for intake valves other carbon buildup.

I've had nice results with Sea Foam.

I'd go w/ the sea foam!

I don't know... I know Sea Foam advertises itself for small 2-strokes, which a 200hp Yamaha definitely is not.
I'd be a little concerned that it might reduce the effectiveness of the lubrication.
The only additive I'd recommend is fuel stabilizer, without checking with Yamaha first..
