'09 X45 Spark Plug Wires.

Has anyone had to change their wires out?
The recommended ones cost $826 from Mastercraft.
Need an equivalent of Plug wires 756003 for an Indmar 8.1L Vortec.

For some reason thats what i hear about the 8.1 at that rate you could have them custom made locally. I have the 6.0 in my 45. Im sure some one will come along with the hot tip but i dont know of one. Have your tried SKIDIM?

Thanks, I orderred cables from Summit racing. $121, I hope they are long enough.

Let us know. I had a thread on this same topic a few weeks ago. How many hours on your plug wires? I have 600 hours on mine but they are from 2001 (boat is a 2002 but built date was July 2001).

Bump
Emailed OP a few days ago but heard nothing back
Anyone know if other wires will work? Paying $800+ for new wires is highway robbery

Just got a cross reference part number

CRU-RK120019.

Search Amazon for "RK120019" and they come up for $75.60.

Anyone use these yet on their 8.1L Indmar engine?

Just talked to Indmar and their customer service person gave me a link to a cross reference they use for 6.0L, 6.2L, 8.1L Gm LS3 & LSA engine ignition wire sets.

Complete wire set for $45 plus shipping.

These are endorsed by Indmar. I ordered a set as mine are original to my boat which is 20 years old this summer.
