94 Mariner 150 EFI, burnt piston

[geaman44]

I have a 150 EFI 1994 Mariner and burnt the #6 piston all other cylinders and pistons look fine, where could I look for the problem that caused just the one piston to burn. Thanks for the help.

A lean running condition, Possible fuel delivery issue to that cylinder
