I have a 2004 mercury 200xs, I was getting ready to install the motor and it fell and cracked the air plenum, just my luck!! The problem I am having is finding a replacement seems to be on back order and its showing part# 850248T03, my question is there any other plenum thats interchangeable?? They all look extremely close to the same and I would really like to run my boat this year. I have called everywhere in the US and searched the web and I am not having any success. I was hoping a Mercury tech or someone could chime in and my motor serial# is 0t819305 thanks again for any help.
