I have a leak that I cant figure out after I reinstalled the power head on a 1987 50 hp. I don't want to pull it again if someone has some advise. It's leaking just behind the bottom left corner of the exhaust box. I pulled the exhaust box back off and used 847 on all gaskets but no joy. I'm pulling my hair out. I attached a picture of where it';s coming out while running. It pumps good water and runs good.
