Coil wire install

[SeaRayboater95]

Hey Guys and Gals, quick question. I am working on a 2012 Larsen with a 4.3 Mercruiser. Changing wires and plugs and the coil wire was glued in. Had to rip it out and left a bunch of that material in the coil. Was going to clean it out and the book says to apply some insulating material in there. Is this necessary, and if so what do i use.

Thanks,

Ken

I would normally go with Dielectric grease in this case, but not sure what the manual specifies

Thanks Mike for your response. The manual calls for "1/2 oz insulating compound". Not sure what that is.

what "book" It's been my experience that it needs to be clean. the dielectric grease would be fine.

I usually use Dielectric grease as well. When I removed this wire from the coil, it was glued in there pretty good. I've never seen that before. figure that was still factory installation.

Thanks,

Ken
