For this hull or a different hull? Problem with the widowmaker is the stock location of the motor is wrong should be more aft and the hull doesn't handle much speed very well or turn very well for that matter. Theirs only 1 guy I have read that has this hull running well and did A LOT of work to get it running that way. With all that said the stock motor and this esc will be fine together. If your talking about a different hull you will need to add more information to get a accurate answer...
