I used the Prather 225 and my boat ripped. I had the Castle 1520 w/ 180a ESC

Here is a video of my Spartan running that setup.

Yes, the X646 will fit your prop shaft. The Spartan has a 3/16" shaft size.

I would be cautious propping up too large on the 1800kv motor. I tried running a 2000kv motor with a prather 215 and blew the ESC.

I would suggest starting with an x642 and see how things go before propping up any more.

Also, be aware that metal props require balancing and sharpening before running them.

man thanks a lot for the help well which prop would be cheap and ready to role

Composite props like these are the alternative to metal props. http://www.offshoreelectrics.com/pro...t=Carbon+Props

The 42mm prop is pretty much the same as the stock Spartan Prop

The 45mm might work ok, larger diameter, but not overly aggressive on pitch.

These props are cheap and ready to run. The down side is they chip easily and they flex under load so you loose some performance vs a similar metal prop.

You can buy metal props already balanced and polished, but they are pricey ($35 - $50) and there is often a wait time while they are prepared.

If you go with composite props, buy 3 or 4 at a time, they do chip easily.
