As Pat said.....200 is not hot for that HP.
Using an electric water pump does have its drawbacks. Understand that an electric pump flows X number of gallons per minute(GPM) whether you are going 100 or sitting at idle, it flows the same. If the car is at idle or just in a cruisng situation 25-35 mph , you are not using much HP so you are not making too much heat so the pump can keep up with the cooling.
But once you get out on the highway and start doing 55-65 mph, you are using more HP and making more heat, but the pump is still flowing the same GPM as you are at idle. Upside is the airflow is better at speed so it can help out alot.
A belt driven pump can be overdriven by using a smaller pulley on the pump and larger on the crank which will push more coolant at low RPM and even more at higher RPM. You are limited with an electric pump.
But again...........200 is not that hot for that HP.
