I have a 50 hp evinrude # E50TLCO that I got used from a friend. Just recently I starting having problems with my motor. It starts fine but after about a minute it idles down and shuts off. I'm not sure if I should take it to a shop or if this is something I should be able to do myself. It idles off, wether in gear or nuetral. I also noticed some oil leaking from the mid section. Does anyone know what the problem might be. Thanks in advance.
