  8. Westerbeke L25 for sale running

    If anyone has any experience with temperamental Westerbeke engines, namely the late '70's Four-91, we could use some help. 1. We broke the secondary fuel filter assembly and order a new one. Turns out Westerbeke superseded the part with a slightly different fuel filter assembly. The head has...
