My 1972 omc started making a slight noise so I shut it off and checked the fluid levels. The upper was a little low and the intermediate had practically none. When I tried to add oil to the intermediate it began coming out from behind the ball gear. I am assuming the seals are shot behind the ball gear. I am on a tight budget and need to try and fix this myself. I need to know what is involved with changing out the seals. Thanks for any help. Rick
