    Default How long will these berkeley castings last?

    I have a 18' jet from 1976 with a berk pump. The motor and pump are both rebuilt and tight and the hull is solid. The berk castings still look good but I gotta wonder is the aluminum metal fatigued or not.My hp is 400 roughly so I'm not stressing anything.Anyone got any info on this? Thanks.

    Well that is a GREAT question 464jet!!

    All the Berkeley castings are 356T aluminum, the T is for heat treated, this is the best type of casting you can buy. After machining the parts are hard coated to military spec's , that why the cast last so long its all in the prep work and the quality of aluminum being used. 34 years in service and still good shape, not bad.

    Thanks for the question,
