"It turns out my old water pum

"It turns out my old water pump was on upside down as my old engine was a reverse model. Single engine Marinette. Now I have a new/remanufactured 318 standard rotation model. What do I have to do to make the switch? I know the distributor gear, prop, and starter need changed. Any thing else? What do I have to do to the transmission? It is a velvet drive 1:1 71c model."

Only issue I can addr

"Jeff, if I understand, I need a different starter (which I knew)and different distributor and gear. How do you deal with the trans oil pump?"

The front of the trans has to come apart to reverse the oil pump. Never done it myself, sorry.
