Re: Power Flow?

Power flow ports on a two stroke outboard are generally exhaust ports.

L. I. Chuck,<br />If thats the case should there be any water coming out of them mixed with the exhaust?<br /><br />BTW..Its a 88 6HP Evinrude..I see exhaust bubbling up from the bottom of the lower unit when I run it in neuatral..how many places is exhaust suppose to pour out of this thing?<br /><br />Thanks for the help..

Re: Power Flow?

Hi G.M.<br /> Generally, exhaust comes out of two places on most modern outboards. The holes above the waterline are "exhaust relief ports", which are needed to help with low speed and neutral idling. If all the exhaust were to exit under water in neutral it would effectively drown the motor, as it wouldn't be able to overcome the backpressure of trying to push the exhaust out underwater. Once in gear, most of the exhaust will exit underwater, as forward motion and propeller movement will draw the exhaust out...<br /><br />- Scott
