  Fits to the precision electroweak data that include the NuTeV measurement are
considered in family universal, anomaly free U(1) extensions of the Standard
Model. In data sets from which the hadronic asymmetries are excluded, some of
the Z' models can double the predicted value of the Higgs boson mass, from ~ 60
to ~ 120 GeV, removing the tension with the LEP II lower bound, while also
modestly improving the chi-square confidence level. The effect of the Z' models
on both the Higgs boson mass and the chi-square confidence level is increased
when the NuTeV measurment is included in the fit. Both the original NuTeV data
and a revised estimate by the PDG are considered.
