I am planning a tune-up this offseason on my single 2007 Mercruiser 496 MAG. Two questions:
1) Besides spark plugs and wires, what else is recommended during a tune-up for the 496?
2) Spark plugs were easy to find; however, OEM plug wires seem to be cost prohibitive ($600-700). What are the alternatives? There are AC Delco marine wires at places like MichiganMotorz.com for $55.95. What can be trusted for extended use on the 496?
