I've been interested in the Merlin single seat from Aeromarine. Chip has been successful with the HKS 700 which is appears to be 121 lbs dry with all the accessories. Pete has the 0-100 at 105# dry as pictured on his page so add exhaust, carb heat shroud and oil cooler, the two should be about the same weight. The width listed on Wikipedia for an 0-200 is 31.5" and the cockpit width (assuming that is interior) of the Merlin is 27.5" That's manageable for a fully enclosed cowl. May have a bump or two, possibly sides wider before firewall for the heat to flow out. The HKS take off power is 60hp, the 0-100 should be somewhere in that ballpark. I know Chip had wanted an 0-100 for that plane so he could build a firewall forward kit. All very nice in my mind.

I really like the Merlin, and I believe that the O-100 would be a very good engine for it.

The interior has limited leg / knee / shin clearance for me, at 6’ 2”. Repositioning structural components would be necessary to make more room.

That's disappointing to hear. I've only seen one at Chip's home airport. It was being built by one of his friends who lives there. The demonstrator was at a show. Couldn't sit in it, no seat and wires all over the place.

Being a shorter, but wider type(5'6", 200 pounds) I fit in it just fine with plenty of room in all directions as I found out at Oshkosh last year. There was a guy right next to me over 6' easily and he also fit well with more than enough knee/head room. Agreed, always a good idea to try an aircraft on for size beforehand so you know for sure.

Friend here is discussing with Chip. Advises that Aeromarine's Merlin PSA is changing over from the HKS 700e to a V Twin engine adapted from an ATV. Chip is about to begin full flight testing. FWF approx $8k. Details on the engine in a trike here...
Here is what the owner/pilot says about the engine:
"Engine is an 800 V Twin from the Hisun utility quad, 61 hp is gentle tune from a four valve motor, they are sold in the USA. Redrive was machined by a Brit friend who has a factory in Ooty, India, price point is low for the quality. "

There's an ultralight manufacturer saying on Facebook that the O-100 project died. Say it isn't so! I won't mention which company is making the claim, but can anyone confirm that the O-100 is still on track?

If it was technical issues one would hope they would post the problems so we could learn something

Absolutely not true. Is it Aero Marine? I know Chip wanted it for his Merlin and likely gave up waiting.

I spoke to Pete 3 weeks ago and he was still building the 10ea production engines he has in stock. When we spoke he was planning on having a full build filmed by a professional film crew and asked me to attend, but I was so busy I said I am locked up until 2nd week of September. Unsure if he put the filming off or not for the time being. He had a few non engine related setbacks recently and that sidelined everything prior to C19 and now I am sure C19 is not doing him any favors.

But absolutely still moving forward...albeit slowly

I would also have heard if it died, and AFAIK it has not died. It has gone through the same amount of development and engineering and revisions as any other aircraft quality engine, but in this case it was one or two guys and not a 500 person corporation with money behind it. Same amount of talent, same amount of effort, just done by one saintly person.
