Our family owns a 1982 B130 BMW Marine stern drive. This unit has been very reliable.
BMW no longer manufactures marine propulsion units. The former New Zealand distributor no longer carries parts. This makes it very difficult to identify and obtain the correct parts.
The table below shows some of the current replacement parts we have been able to obtain. We hope that other B130 owners find it usefull.
