A new four-stroke engine for Quicksilvers resulting from a fascinating collaboration of two light aircraft companies — a pairing I would not have predicted — was unveiled at the 2022 SUN ‘n FUN Aerospace Expo.
Air-Tech, a Quicksilver dealer, and Blackhawk Paramotor got together at the 2021 EAA AirVenture Oshkosh show to hatch this idea (they displayed immediately next to one another and started talking…).

At SUN ‘n FUN 2022 Air-Tech’s Ken Borne fired the new Aero engine up for journalists and prospective buyers, but they haven’t flown the engine on any of their aircraft yet.
Now, perhaps we’ll see this collaboration take to the skies. If all goes well, I predict a strong interest from buyers.
I’ll be looking for news at Oshkosh 2022 about how well that engine performed and whether it could sweep through the thousands of Quicksilvers flying.
Many owners have said they prefer a four-stroke powerplant. When their current two-stroke engine needs maintenance, a significant number might switch to four-stroke.
Owners like them because they are quieter, more fuel efficient, have longer maintenance cycles, and have a deeper sound many pilots like.
In addition, some locations are clamping down on two-strokes that are perceived as “dirtier” or louder or less dependable.
Not a shred of information about the engine. Only that it is a 4 stroke. How about something like a photo or the HP rating? Would love to have a little more info? Thanks.
