If you wanted engine separate, the only things I would not include with the engine assembly would be the hull, steering rods, gearbox and
bare radio box. Everything else could go with the engine.
Selling my 53 Ossi tunnel hull with outboard. Engine assembly and prop are completely new. Never been started or seen water except the lower only. Gizmo 30+ engine, Gizmo exhaust cooler, Lawless lower with extra shafts, ATR Pipe and ATR bored carb, ServoCity 5:1 gearbox with Hitec HS-805BB...
I'm in the U.S. The hull was ran a couple times before me. I bought the hull bare and built the rest myself. I bought the Lawless lower used. Literally everything else is brand new. Never been started or seen water.
