1993 evinrude 115 maintenence port

[mstpierre77]

I am trying to determine if my motor does in fact have a maintenance port that can be used to fog both carbs at the same time. I found a box with a red quarter turn switch on it and three lines coming from it. Is this it? Is there any reason I should pay to have the motor flushed with antifreeze and the lower unit wrapped from the dealer? I want to do it right but as we all know saving money is on everyone's priority list too. Thank you very much.

The port should have dust cover like on a tire valve stem. If so you are at the right place, just screw on and fog away. I have a problem keeping motor running doing it that way, i rather spray into each carb. and into each cycl. through sparkplug holes and then let sit. just my 2 cents
