My recommendation is to keep the 6 hp and enjoy it.
Why do you want to change?
I'm not the OP, but I have been considering changing to a 2hp secondary engine on my C-Dory 22 Cruiser. The main reason is weight. First of all, I would like to have less weight overall in the stern. Second, my boat lists to starboard, and there is not much other "big weight" I can shift to port (the secondary engine is on starboard). Third, leaning out over the transom to lower or raise the secondary engine I have now is hard on my back and potentially hazardous (that could potentially be overcome with a "stick" type lifting handle).
Right now my Honda 8 (fancy model with electric start) weighs 108#. A Honda 2 would weigh 28#. That's a savings of 80# that sits smack on the starboard transom. The 2 would be much easier to lift/lower, and I could even take it on and off the boat without a team of mules.
If I used my 8 for anything but a backup engine (say if I used it for fishing), well then I would probably find it well worth it. But I don't. It's there solely to get me out of trouble if need be; I basically run it just to keep it in tune for such a day. For my purposes, that usage is "getting over to the side of the road" where I can anchor and sort things out, and/or potentially to putter slowly back to port.
Given that I have considered going with just the single engine (main), adding the options I'd have with a 2 hp outboard seems like a big plus. I say that because I realize that a case could be made about how much "less" I would have than I do with the Honda 8 (that's also true, but I'm turning it around to look at it from another perspective, i.e. that of having no secondary engine at all).
I'd say it's always a matter of a person subjectively deciding where to draw the line on spares and tools (of which an engine is one). Do you carry a second engine at all? If so, how big? What are your expectations such an engine? Plane back to port just like you do with your main? (Then don't get a 2hp). Do more like what I am thinking (anchor, sort things out, putter along)? Then it could work. I can see someone going anywhere from just one of everything to a whole second boat (all the options

).
I don't plan on having a powered dinghy now, but I suppose if I did then the 2hp has an additional plus as a dinghy engine.
I don't have any illusions about the Honda 2 - I had one on a previous boat and they are noisy, vibrate, have a small internal tank, and are a pain to start (for me). But they do a job and are a manageable weight.
Not that this is directly applicable, but one day I saw a dock neighbor puttering slowly in on his Mason 42 (sailboat). Turns out his (main boat) engine had quit something like 10 miles out, and he had strapped his small dinghy (with Honda 2) onto the hip and puttered on in. He even docked it

Granted, conditions were calm, but that's partly because he had anchored to wait for the best tide/wind conditions (this was in BC, so tides were a factor). There can always be extreme stories in either direction, so I only post this as an anecdote. There could certainly be times a Honda 2 would be inadequate.
Anyway, those are the thoughts of one person who is considering changing from an 8hp Honda to a 2hp Honda (wish they made the Suzuki in a long shaft).
