I am looking to get a 2nd prop for my 2007 Yamaha F60. My hull is a 2007 Mitzi - non tunnel. The current prop is a stainless, 3-blade prop. I don't know much more about it but it says 'G 14' on it. The boat is kept in a remote location so I think I should get a 2nd prop so I always have a spare. I'll either use the new prop as a spare or primary. Any suggestions??? I really don't know much about this stuff. I typically run a full load on the skiff. Depending on wind I'm seeing #'s in the 4900-5300 range and speeds of between 30 - 34 mph WOT.
