Solved I bent a metal tab when installing the water pump. This caused not enough water to be pushed through.

Yamaha 150 TLRQ is overheating. I've tried everything I know how to do. New impeller, new thermostat, etc. Any insights would be appreciated! Update it seems the right side is overheating (more than the left)...based on a very scientific "put my hand on top of the cylinders".
