Volvo Anode - New/Old versions

Volvo Changd the tread standard in September 1993. Therefore there is two different types of anodes refered to as New and Old. 

Note
Please be careful when order. Several boats built before 1993 have changed engine and transmission since new. Often the propeller shaft is also changed. Therefore it is likely that also boats built before 1993 have a "NEW" shaft with new treads.
