Evinrude Air Box

[newf1]

I have a 1985 20 HP Evinrude that is only used in fresh water. I noticed that some outboards have an air box attached to the Carb, mine does not. Is this part essential to motor operation? What is its purpose?<br /><br />Any help is greatly appreciated regarding this to this topic.<br /><br />Thanks

Hi Newf1<br />Its not called an airbox, but an attuenuator, on larger engines itused to as part of the air/fuel mixture (eg if you remove it on a larger engine you acctually end up running Leaner @WOT<br />On small engines it was ussually just away of cutting down th e sound of the carb.<br />If it didnt come with it dont worry about it.<br />Hope this helps

Thanks for the help fellers. I'll do without the part as it runs well without it.
