I generally only research what I get,so im still learning abot marine also,so we are in the same boat,but a few out there know lots more.
No I wasn't aware...I love the Kingfisher,only seen two for sale,and I let one get away:(

I agree,im possitive the top is Std Victa mower engine,and yes cowl assy is not what I know to be Mermaid...

What I would like to see is a correct mermaid with the generation 3 Victa engine,and how its cowl is positioned compared to the early gen 1/2 engines,as you said Mermaid ran into the 60's and ive only ever seen the earlier Models. But im assuming its the second Outboard in the previous Mermaid Ad of the 2 Mermaids and cromer?

I may be getting another Victa marine of a mate,which is not Mermaid nor seems to be A generic brand with gen 3 Victa engine.
Its running an unusual cowl with the gen 2 125 engine, and it doesnt seem to be homemade,ill keep you posted if I aquire it:)
