Terry, the RTV helps the freeze plugs to seal. The Brass plugs are the best, IMHO and usually go in fine if you use the right sized driver (socket). Just don't drive them in too far or you'll be saying bad words trying to get them back out. I usually drive them in just so the lip of the plug is right at the bottom of the taper of the freeze plug hole. '
If you're buddie's boat is blowing out freeze plugs, he has a serious overheating problem or a thermostat that won't open.
