I have just put the lower unit back on my Johnson GT 100. I noticed that where it conncets to the upper unit there is one place that is seaping a little water when it was on the flusher. is this something i should be concerned about? I am sorry if my questions seem trivial. I am pretty handy, but fairly new to marine engine rerpar and do not want to do any damage. All of your help is GREATLY APPRECIATED!!
