ok,

for whatever reason, I can never seem to find parts that everyone else has access to... my searches always come up empty. so, I have seen things like chrome valve covers with Mercruiser logos, and 425hp and 500hp (just as examples) flame arrestors with Mercruiser logos, all for sale on here used, and can not find anything like this anywhere. frustrating.

any help would be greatly appreciated, seriously.

All those parts come off of Merc Racing (blue) engines. You can order them from Merc, but they are triple the price of comparable non Merc stuff.
www.mercruiserparts.com
Best bet is to buy the parts used.

Griff,
thanks for the help, I had seen that site before but didn't go into the parts breakdowns to see what was there, unfortunately everything I was looking for is NLA. you are right, aftermarket is cheaper, I was just looking for the genuine appearance. thanks.

Blue = lots of green
