I have an 82 Mariner 25hp serial # 695-311253. I have to replace the water pump housing which is on order, and from the schematics that I have found it shows a seal that goes between the metal cup and the housing itself. The problem I have is that the seal in question (part #94807m or 95653m) is obsolete! I am wondering if this seal is needed and if so can I use silicone or something? If so how much would I use!
