Which prop? Help please....

I have been digging though countless threads and cant find an answer so hoping someone can chime in. Boat is the BJ29 V3 on the original motor and 120ESC running 6s. I am running the x642 prop now, OSE strut and Heavy duty flex and hitting just a tad over 55mph. Was looking to go with the ABC 1716 prop but i can never catch it in stock. Will the 1816 be too much prop and overheat it? I would like to squeeze everything i can out of it stock before the motor and ESC upgrade. My next step in about a month or so will be to upgrade to a 180 esc and a leopard 4082 2000kv. Will the 1816 be a good fit for that motor? If not what is a good choice?

The goal is for the highest top speed. something north of 80mph until the hull explodes then ill probably build a Aeromarine mean machine or something. :rockon2:

You want an octura x440-3 (3 blade prop) you should be able to get around 60mph (with one from dasboata on here). The ABC 17 or 18 series will eat that stock 3910 motor alive very quickly on 6s. My Miss Geico 29 ran 78mph on my last outing with a 1716 prop from dasboata with the new Dynamite 3831 motor. I'm hoping to be right at 80mph on my next go at it.... if I am lucky (or at least that's my goal).

Any opinions on which prop for the 4082 2000kv on 6s?
