Do I need to plug the old speedometer hole in lower unit?

Question

I've got a 85 mercury 90hp. I droped the lower unit down and replaced the water pump. I noticed that someone has plugged the old line that went into the speedometer area. When I lowered the unit down it broke the line. Is this something I should worry about? water will enter this hole. Not sure if it is sealed up in the gear area.

Answer 1

It won't hurt anything, water cant get into the gear case from the speedo inlet.
