Time to replace spark plugs
Curious what brand spark plugs people are running in their boats these days. My 6.2's are due for a change.

AC Delco or NGK.

If you choose to use NGK make sure you buy them from a reputable source. If you search for the best price on-line and they are from a not well known source, you can very well end up with black market copies that look exactly like the originals, even the box is a near dead on copy. The market has been flooded with these Chinese knock-offs.

I know with a car I replace based on miles
what are some of the performance issues with a boat that would indicate that the plugs needs to get changed out
I know this is a dumb question - but I'm really new to this mechanical stuff --

iTrader: (1)
Wires: 10+yrs on stock black motors.
Regular plugs - every 2-4yrs. Same with cap/rotor. Black motors again.
Platinum/Iridium - when you feel like it. 5+ yrs probably a good time to replace.
Above on fresh water and usually covered boats.
High performance engines - before they get used up. LOL.
