TP 5680 800Kv 4Y Prop Size?

[wedgewalker]

I am running a single setup in a Central Marine 51" Victory Cat, I am running 2x 6000Mah 6s Giant Power Kitty sticks for 12s= (6000Mah) w/ a Swordfish 300a X+ esc. on a TP 5680 800Kv 4Y. I am looking for suggestions on good prop size. I have tried Octura X455,X457 and X460 2 blade but seem to have heat issues. My Prop is 3 5/8" bellow transom overhang at centerline on stinger w/ slight upward angle, my temp on my first run with X457 was 54c to 59c on esc, I didn't IR motor but I feel this is too high, Surface water temp was about 84F to 86F on a hot Texas evening. This was a 2 min. run on straight runs turn and repeat. What would be a good prop size to run for better times and lower temps? Could or should I go with a 3 or 4 blade prop and would this have any benefits or should I stay with 2 blade and drop down to X445,X447 and X450?
