need help with esc choice

[nicksrc1991]

motor is nue 2527 1250 in a 36 inch cat. so 2 4 cell making 8 cell and swordfish 300 amp esc. or 4 3 cells making 6s2p and swordfish 240 amp? any suggestions

I assume you mean a 1527 Neu.
1250kv will produce a lot of RPMs on 8S.
Are you going for Straight-A-Way (SAW) speed, Oval Sprint racing, or just sport boating?

Doesn't matter if you are doing 6S or 8S... a 300amp ESC will give you more room for growth and experimenting with larger props to maximize speed.
