I just got this motor out of storage its a E35ELCND which i believe is a '82 35hp electric start longshaft. Does the engine have to be running in order to shift? It wont budge if i try spinning the prop and shifting at the same time. I drained the oil in the lower end and it came out very black, no signs of water but it is very black, is that ok?<br /><br />Thanks<br />SDS
