Hi All,<br /><br />I am new to here and have just purchased a Fletcher 155 Arrowsport with a 80Hp Mercury.<br /><br />I need some help with a couple of things:<br /><br />1. Can anyone give me the build date of my engine - serial number OB371405 ?<br /><br />2. I need a new prop but can only make out the following off the old one:<br />48 7_31_ 41__<br /><br />Does this make any sense to anyone? If not can anyone recommend a prop to suit a 15.5" Fletcher with a 80Hp Mecury.<br /><br />Thanks in advance.<br /><br />Kevin
