I have to choose between Permax 400 motor or http://robokits.co.in/shop/index.php?main_page=product_info&cPath=2&products_id=212 for a speed boat. Please suggest.

400 brushed motor is quite suitable for an rc boat. Geared motors are used in Robotics & rc vehicles where power transmission/ torque is the prime factor than speed.

Which ESC can be used for that motor?

The premax 400 will be a good choice for your boat, In fact even this http://robokits.co.in/shop/index.php?main_page=product_info&cPath=2_3&products_id=208 would be a good alternative depending on your design.
