Thermostats
BULLETIN NUMBER: 107 /
Beginning approximately May, 1980, thermostats supplied by the
factory
have a by-pass hole sufficient to allow adequate water
flow through the exhaust manifold, head, and block, during engine
warm-up.
This flow is mandatory, especially in the case of marine engines
and generator sets which have significant load applied soon
after start-up.
We strongly recommend that only genuine WESTERBEKE thermostats
be used in WESTERBEKE products to assure proper design in this
regard.
