While having the manifolds/risers replaced on my 5.7 mercruisers, the mechanic has recommended that I replace the plugs and wires back to the distributor.
I am going to do it since the access is soooo much better with the manifolds removed. He says that the wires are all carbon based now to reduce radio interference and only last about 300 hours. He says that you experience a slow performance reduction unless changed.
I did not know this, I assumed that plug wires either work or you start getting a miss but what have others found. I do know that the new electronic ignition systems really put out a high voltage to the plugs. His advise in other areas seems good. I have about 350 hours on a 10 year old boat.
Curious what others have been doing.
