Hi Myke. Yup, that's a '61 model. Here are some great links that will have you up and running again in no time. You can get any routine parts you may need for the job like carb kits, impellers, coils, etc...right here at iboats for about $20 each.

Maintaining Johnson E & FD Serie
1961 Johnson FD-15 18 hp Outboard Motor Parts
3 HP Evinrude Lightwin Ignition System Tune-Up 1952-1967 (great ignition rebuild link. It's for a different model, but all of the steps are the same for your motor)

So, i changed everythin on my johnson 18, new coils, condensors, points., turned it by hand before i tightened the flywheel , everything was good had a nice blue spark. Put the flywheel on zapped it with my 3/8 impact quick. threw on the recoil and was gonna try and fire it up. Pulled it, sounded kind of rough, took it all apart and the cam the followers ride on was cracked. Anybody know where to find this part? on marine engine.com the part number is 0316583. Pls help

Hi Myke. Impact drivers are great for removing a stubborn flywheel nut, but it needs to be tightened back down to the proper spec with a torque wrench. I think the impact driver might have over tightened the flywheel nut causing the cam to crack. I would check ebay, aomci.org, or bite the bullet and buy one from marineengie.com. The good news is that a cam from any 18 hp should work.

In that case, ebay, aomci.org and asking around here in the forums are probably your best bet.
