Replacing spark plug wires

[Bluelake]

Hey Y’all,

I am replacing my spark plugs in my 18 Axis with the GM 6.0 409 monsoon and decided not do wires yet because of the availability from Bakes. I replaced all the plugs and got down to the last one and the wire was stuck and so I damaged the wire and have weekend plans. Could I replace all the wires with just genuine GM 6.0 spark plug wires from napa like the ones I put on my truck. They look identical to the ones on my truck. Not sure if it would work but at-least I could boat! 

 

Thanks Jacob

I’m not sure about the GM motor but I know the plug wires on the Indmar Ford  6.2 are OE Motorcraft plug wires so I don’t see why you couldn’t just replace them with stock GM wires. I would take one off and take it to the parts store to make sure it’s the right length, better to be safe and not have to make two trips. I haven’t priced plug wires but I know you can get spark plugs a lot cheaper buying from a parts store instead of an online marine parts dealer and they are the same thing.

The length will be the tricky part. Just measure the resistance in the new wire and make sure it is better than the old one or same wire opposite side. It should be no issue.  Some auto parts stores let  you buy one wire.

I have a feeling that the "marine" routing of the spark plug wires on our boats make off the shelf kits unfeasible.
