Hi All; I'm very new to power boating. I just purchased a 1989 198CXL Chaperell boat. It is currently equipped with a 4.3L Alpha One Mercrusier stern drive. Currently there is no prop, What I'm looking for a an alumimun prop, somthing that will let me pull a skier, or a coulpe of people on a tube. The boat would probably be loaded with four people max I friend told me to look for the four blade variety. Thanks for any help.
