spark plug wires

[QWXZAS12345]

im wanting to replace the spark plugs on a 1971 mercury 650. I was wondering do i have to use the marine (expensive ones) or can I just go to an auto parts store, buy a kit, and cut them myself????<br /><br />boatyboat

You'd be best served by buying marine ones. They screw into the distributor cap. They don't just push in like a car.

Well, I've got 87 90HP Merc that I've used automotive plug wires on and never had a problem. The parts were only a few bucks at the Napa store. My marine dealer wanted around 20 bucks for a factory set. <br />Good Luck

I would say marine set if your running in saltwater but I used auto wires for a long time just if the motor starts acting up check those first they do tend to work lose every now and than

By the way, if you decide to use the automobile trpe or marine, Be sure to purchase a tube of electrical grease. This grease will prevent corrosion at the terminals and help waterproof the connections.<br />
