Mercury 200hp Heads or Head Covers

[RiPsTa]

Sorry, i forgot to put WANTED in the title

I bought a dive boat recently with a mercury 200hp which i didnt take much notice of but now i realise that it doesnt have any head covers on. I never noticed as i have never seen an engine like this before. I believe the covers are not available anymore and they changed the design to a one piece head. Alternatively if you have some one piece heads i would be interested in those.

Cheers Chris
