New Plug Wires

[Skip ThunderBolt]

It is cold in Louisville on the Ohio River, and I thought it might be a good idea to replace my plug-wires and spark plugs this week. I have a 1989 Sea Ray 390 with HUGE Mercury engines.

Any advice on a good plug wire brand and plugs?

Thanks as always for the advice.

Been through a few sets of plug wires on our 496 mags. Put a set of Scott High Performance wires on last year. Recommended by a friend that races drag boats.

I replaced mine with Mercruiser oem replacements. Nit cheap but according to 3 shops around Lake St Clair highly recommended. Don't cheap out and plugs at the same time.
