I need to confirm plug gap setting on my 470. Its an 84 Mercruiser. The Manual spec I have shows 25 to 30 on the plugs and 17 on the points.
When I pulled the plugs that were in the boat the plug gap was in the 35 to 40 range.
I am figuring the manual spec would be correct but wondering if there would be a reason to over gap.
THanks
