Some More Engine HELP!!!

[Heywhire]

Can anybody help with the ID of this engine. I know it is an OS Max .21 Marine engine but what model? I have gone to the OS website and went thru there discontinued engine manual and none of them look like what I have. I would like to know where to get an exhaust manifold for this and what pipe to use. I am going to put it in a rigger if that helps any.

Thanks Again for the help.

Tim is right. It is a .21 SE-M. You have the newer version as the early ones used two set screws to hold the carb instead of the cinch bolt.

Macs used to make a marine header for this engine. I am not sure if Macs still makes them since this engine is discontinued.
