So I don't believe my 2004 220 select 5.0mpi has the cool fuel gen 3 model but I wanted to see if someone knew for sure. I hope to avoid the delamination issue experienced by this model. My engine serial number is 0M678324, boat is a 2004. If I look on the mercury marine parts catalog it appears that my boat does not have the gen 3 but I wanted someone with a little more knowledge to confirm my findings. Thanks in advance!!!
