genesis 900 prop

[wildphil69]

wondering what you guys would recommend for a genesis 900 with leopard 1600kv 4082 on 6s? I am new to the whole fast rc boat scene so as far as props i don't know much but i was thinking a cnc aluminum

cnc props are junk.
get an m445 octura and sharpen and balance it or a x642, but watch the warnings and how to vids on the you tube before you start grinding away at an octura.

Ok. would a three blade be better? i notice some cat guys like them.

I'm no expert, but I read a post somewhere at some point that 3 blade props create less lift which is for some reason better on a cat. It made sense when I read it.

I think this was the post I was thinking about.

Looking for suggestions on props.I am building a twin genesis.Here is the particulars.2-3674 leopard motors,2800kv 2-120amp esc
hobbywing seaking,flex shaft are 3/16", escs,2-stingers.Trying to find out what props would suit this build,and so I do not fry the motors.Also runningn2-5000mah 50c,not sure if I should go parellel or series.

4s each side with 440 props will be a good start and a fast boat out of the bag.

Thanks;
I all ready have 2-5000mah 50c lipos,so what props would you suggest.Deciding which prop to use is hard.There are so many variables to consider.I would like to buy them already done.They are both 3s lipos,and I would like to use these insteadof forking out another couple hundred$.By the way;I am twinning the Genesis/if that helps.
