Should I add Sea Foam Marine PRO to 2-stroke oil in an Evinrude E-TEC [SOLVED]

I have a 200hp Evinrude E-TEC that I’ve always used regular Sea Foam in. My question is, with the new Marine PRO product, is it a good idea to put a little in my 2-stroke oil reservoir with the high pressure injection oil? Please let me know if you need any more information in order to answer.

Thanks for the question Bruce. If you take care of your ‘stuff’ and use your outboard regularly, I don’t think it’s necessary to add Sea Foam [or Marine PRO] to a 2-cycle oil reservoir. Exceptions would be to help liquefy heavier 2-stroke oil that will form at the bottom of the oil tank or if you needed to clean a varnish restriction somewhere in the oil-injection system. Can definitely run Marine PRO in your E-TEC’s fuel!
