Those round blue head novarossi 21 are old. I believe they were 4 ports as I recall. They were short stroke motors. Todays novas are a longer stroke than those. These are pre mid 90s vintage. Right when I was starting boating.

Got one of those engines in a steve muck spartan(?) that really gets with it! Makes me wonder how much more performance I can get with a newer style engine.
 
Ok... now I gotta get organized if these engines are to find new homes but I have 3 1/2 truckloads to go through boats engines and parts. I am at a loss for values so I might pick on someone for some market info if I could.

Interested in your (2)CMb 21 blue head engines you posted on your first post.
Yeah I got the message earlier but now I have matching CMB pipes too. I have no good idea what the values are that a NIB pair of CMB engines with pipes is. Have some homework to do I guess just want to be fair with everyone and myself.
