Yamaha 115 2 cycle oil overflow issues

[dgold_881]

My dad has a 1987 Procraft boat with a Yamaha 115 2 cycle. The problem he's having is that the oil resevoir in the engine is over flowing while running down the lake. He's replaced the pump thinking there was a sensor out inside it, but the problem is still there. Does anyone have a clue how to fix it? Thanks!!
