Hello Guys. I picked up a '70 20hp johnson at a good deal. The guy sold it for parts only. He robbed a few parts for another he had. He did say it would run though. I need access to a parts diagram of the whole motor so I can see what all is missing. I've searched online and can't seem to find what I need. Can anyone help me with a lead to a diagram or book?

Thanks in advance,
John T.

Thanks for the links guys. They really have helped. I've picked up some of the parts I need on ebay. Now, I have need for a tiller handle and a fuel pump. I have seen a couple of good buys on the handles but not sure what year models will fit. I looked on the diagrams and compared one on a '62 5.5hp to the diagram of mine. It looks the same. It's pretty cheap. Does anyone know the years that will work? And, what about the fuel pump? Is there one out there that will work which isn't so pricey? Like around $50?

Again, thanks in advance for any help,
John T.

I took the chance on the 1962 handle, it fits and works great. I ordered a new after market fuel pump shipped for $40. Waiting on it.

Thanks,
