I got a 1993 Evinrude 25 hp E25TEETS.

With all the changes to the Champion spark plugs numbers, what are the best plugs to use now? I had Champion LJ774 but they are listed as no longer available.

Another plug that supposedly used to work well for high RPM engines was the Champion L2G. The Champion QL57 is listed as the equivalent to this. Does anyone know if this plug is acceptable?
