1989 155 hp commercial evinrude.<br />What is the difference between cross flow and loop charged engines and how do I tell which I have? Which is more desirable to run?<br />Coming from the power tilt is a cable with a green wire with a ring terminal, a blk and a wht wire going to a round terminal and a blu and a grn wire going to an oblong terminal. Can anyone identify these wires and where they go? I cannot find them in the shop manual. Thanks for the previous help and thanks in advance for any help on this post.
