Re: 1959 buccaneer propeller
Standard prop is 10 3/8 X 12 1/2.Of course final prop size could be different depending on the application. I believe Gale part numbers are the same as OMC parts. Beginning with 3 and having 6 digits. Evinrude Johnson
props will fit.The Gale 25 ran through 63.25 and 30 E/J have the same standard prop.I've found on Ebay that many of the venders have excellent application info ie: what various props fit.If there are no size numbers on your prop( -- X -- a prop shop can measure it for you.You can measure your diameter from tip of blade to center of bore times 2.Pitch is the second and is the key number.Diameter simply follows the design.
