Hi there,<br /><br />I have a Johnson 55 HP 1978. The flywheel has worn teeth and the starter locks itself up sometimes. So I like to replace the flywheel with another second hand.<br />The original part number (in 1978) of the flywheel is 581837. I have found a second hand with number 581836. Does anyone know if these are Exchangeable.<br /><br />Many thanks in advance,<br /><br />Cor
