Prop, Strut, & Coupler question

[alex305v]

I am working on a 36" Cat from R2Hobbies. I recently purchased two Leopard 4082 2000kv with two Turnigy Marine 180A Brushless Boat ESC, and two Octura x447 Props. I need recommendations on a driveshaft, struts, and couplers that will fit this configuration. I don't mean to sound cheap but wife made me this way, so far I have invested $896.97 in this boat and still missing this items plus the two batteries that I need. Give me your best opinion.
