Rolls Royce-Allison 250 c-18 mounted on a Mirage 18' fiberglass tunnel hull boat ,the model is Jaguar Jett ,the hull was originally designed for an outboard then modified for a nitro burning blown big block.I am a helicopter pilot/artist/builder,i came up with this concept after i acquired this surplus Rolls -Royce Allison 250 c 18 engine.I originally was going to build a t-bucket for this engine.Once i realized the amount of fabrication work to adapt the engine to an automatic transmission i ended up doing the boat project.I sold this boat in 2007 to a guy in Chicago,he kept it for around 5 years and then sold it to a guy in California.If anyone knows who has it now please let me know in the comments.I can build another one to order if anyone is interested in owning their own private jet.Thanks for looking and take a look at my art work and merchandise on my website sinontincustompaint.com Join My Mailing List on my site for future project videos.Email me at chopper155@gmail.com
