I have a 1999 mercury 115hp ELPTO that's oil injected. The last time I filled the oil I noticed some leaking out from the motor floor and traced it to a rubber tube that was sitting just above a pool of oil in the bottom of the cowl. My first thought was that this was the injection tube, but I did not see a place nearby that it may have come off from. Do these motors have some sort of overflow tube that drains extra oil into the area described? Seems like if so it's not a very practical area. The tube originates from the top of the oil container and if I add more to the container it will again drain from this tube until a certain level is reached. I just don't want to run the motor and risk burning it up if it's the injection tube that's off. Any advice would be greatly appreciated.
