Maybe not a big deal
I haven't seen a lot of thru-hull strainers, but most that I have seen are pointed with the grate aft, but I have seen them like your new one is positioned also.
Having the grate in either direction is not the controlling factor in the amount of water that comes through the grate. Basically the weight of the boat pushing down on the water, the % of open area in the grate, and the size of the hole in the thru-hull dictates the flow of water through the hull.
The thing that controls the amount of water flow through the motor is the water pump, not the thru-hull size or it's orientation. The bigger the water pump and/or the faster it turns, the more flow through the motor. So as long as you are using a water pump that is properly sized for your motor, you should have no issues.
If you liked my advice/response, give me some rep points. If you didn't......well what do you expect, it was free.
