Spark plugs

[Bad Habit]

Seems I'm not receiving slot of radio transmitions on the VHF when the boat is running. I can also here static from my fishfinder "pinging" on the radio when the squelch is turned down. Could using resister type spark plugs help solve this problem. If so what plugs would be recomended for a 1987 350. 5.7 mercruiser?

Thanks for any advise, Rick

Get resistor plugs for sure. Get your correct numbered plugs with an R in the number. Check all grounds for clean and tight.

X2 on checking ground. If nothing helps get ferrite snap on chokes and put these on affected unit's wires.
