Universal 5411....Hurth Transmission...propeller rotation

My boat is a 1982 Catalina 27. It has a universal 5411, 11 hp engine. Since I have had the boat I have never been able to reach hull speed under power. I recently pulled the boat out of the water for a bottom job and inspected the propeller. It is stamped with 12LH7, a 12x7 left hand prop. Reviewing the specs for the engine and transmission it appears I need a right hand propeller. And likely a larger diameter too.

I have attached a photo of the prop and transmission. Does anyone know why there would be a LH prop on this engine and transmission? Does anyone have any recommendation on a new prop?
