There is a guy that was (still is?) flying a push pull power pod sea

I think you're talking about Ken Welter's old Coot. It burned last year
(Jun 2002 IIRC). Ken has since completed a 4-place Coot, although it is
currently single-engine Wankel-only.

Yes I have here is a photo of my twin pack that will go on the 4
place coot that I am starting to build, I installed this pack on my
present coot and tested it for 11 hrs and was a bit heavy for it but
should work on the bigger one, the front engine is a 670 Rotax
snowmobile engine that puts out 125 hp but there is no reason that it
should not work with two rotary's however part of the design to stop
resonant vibration is to run two very different rpm's so you would
run two different gear ratios and I would suggest running a 12a and a
13b, the spag clutches that I used were made by SSK and sold by Morse.
