I'm working on a 36" "e-jet" now. I had an SK Jr. when I was a teen with an .049.
My pal Dave had a 36" with a K&B 40 and the MRC "Turbo-Trol" (Graupner) jet.
He had a big SKDaddle 60 with an O&R ignition engine too. So between the two of
us we covered the 4-model SK Daddle family lineup. All those boats melted away over the years.
He is building a 36" "jet" as well, I cut out 2 kits for us. I got the jet units from Hobby Lobby (Tennessee) many moons ago.
