Also one more point...the boat has been sitting for a week and its still leaking.
Also, that is correct, the rear transmission seal is not leaking, I checked that first.
I did stop by a boat shop and he said there should be a seal.in the couplet..which would be new to me..but he also sounded very unsure of his answer which is why I turned here. I will take it apart and post pictures incase someone else runs into this.
