Just bought the boat and I am trying to confirm the proper size and pitch prop. I have some documents that came with the boat that look like the C&C original design specs that describe the boat as coming from the factory with:
30HP A4 with 2:1 reduction
Walter V-Drive
15" x 10" prop
Friends tell me this sounds rather large for an A4. I have a two blade feathering prop either Martec or Autostream 500 series that upon sea trial (high RPM little speed, feels like it is cavitating) and upon visual inspection while hauled appeared to have not enough pitch. I am not sure of the size or current pitch of the feathering unit. During the haul the prop was cleaned/scraped and mechanically seemed to be functioning. Before having it serviced I was trying to figure out what the pitch should be set to. I may just put on a fixed prop if I cannot get the featuring one to work.
