Franny Taylor used to sell a kit.
I think I saw 1 kit come out of Don's shop, many came out of Airboat headquarters "Thurman" I've been asked by one person about a kit, my reply? First off, I wouldn't know how to bill it out, second how far do I have to go with said kit.
It feels like getting a gal all ramped and ready, wet, hot and heavy, call in your buddy to finish the job and leave with blue balls, I'll pass.
I will go a step further, a year ago, I built a hull, engine stand, cage, rudders, custom dry boxes, other little custom things, guy picks it up, takes it to another airboat outfit to have it all painted, wired up, plumbed etc, got it all assembled and pretty, great,,, I get a video text on how bad the boat porpoises, so I finally got room to bring it in, have a look at things,, well, I level the trailer fore and aft, put same digital level on the prop hub, engine was 10° down in the rear, ok, build a 3/8" shim for rear mount, engine now plumb to trailer, lifted hull up, gauged bottom, just as I had built it, ok, he picks it up, takes it for a ride, calls, states boat is a completely different animal, actually scared him a bit and not even redlining the engine,,, it just goes to show, you can't just throw one of these machines together, there is a method to all of it!!
