I can't seem to find the correct/optimum prop specs for this engine, even though I have the service and repair manual there seems to be no reference to prop size/pitch/rotation ........ if anyone has any idea I would be grateful :-D

Scroll up to the top of the page parts and accessories tab.just put the curser over it it will drop down click on propellers.
