First off id like to say hello, my name is joe and i live in mesa,az. i just purchases a 79 16' jet-ster with a olds 350 and a jaccuzi 12yj golden eagle. After doing some work on the engine to get it to run for the first time in 16 years i took it to the lake and found out the mechanical seal is leaking. My service manual does not go into depth about changing the seal itself just pulling the shaft. I was hoping someone could give me a little more info on the job. Thanks!
