motor is an evinrude 115hp. v4. it takes about 15-20 mins. to get out of my harbor (no wake zone) about half way out the motor sounds like it loses a cyl. (gets a little shakey, losses power) sometimes it stay's that way, sometimes after 30 sec.- 1min., more or less it will perk right up and runs perfect again. one time it died and did not re-start. the reason i ask about the coils is that the 2 bottom ones (1each side of cyl. banks) have hairline cracks in them. the 2 bottom coils are differant than the 2 top one's, as the bottom one's have removable spark plug wires and the top one's the wire's are molded into the coils and are not removable. is there a way to check the coils? a have a liitle craftsman electrical meter but i'm not great at knowing what to do with it. thank's for any help!
