hello fellow boaters.i was just running my motor on the muffs today and noticed that water comes out the front of lower unit were it disconnects from the motor.its a little square opening.the motor is 1988 johnson model#J110TLCCA.maybe this is just some tpye of cooling overflow past forward/reverse shift housing?i know water comes out several other holes on lower unit guess im just crazy and never noticed this before.thanks for easing my mind and for any help.
