Requirement CFR-33-183.410 or UL1500.
Benefits
Main line circuit breakers come standard on these
model gensets but, in many cases, when the voltage or
frequency is changed, the circuit breaker also must be
changed. These kits allow easy conversion of the circuit
breaker in the field.

0155-3087 Keel Cooling Kit with Dry Exhaust
Spec Sheet Description
Keel cooling conversion for dry exhaust.
Description
This kit replaces the seawater pump with a cover and
eliminates the heat exchanger from the cooling system.
The exhaust has to be converted to dry style with a
separate kit. If the set to be converted has a sound
shield, then the roof has to have a hole cut out for the
exhaust exit and the exhaust elbow and fittings have
to be lagged to prevent heat buildup inside the sound
shield.
Benefits
This kit converts the engine cooling system from heat
exchanger to keel cooling. In addition, if the exhaust
needs to be converted to dry exhaust a separate kit is
required; see Dry Exhaust Conversion on page 47.

Description
The water separator is to be located after the water lift

Benefits
The separator installs downstream from a water lift
muffler, but above the sea level for gravity-forced
draining, and separates the engine exhaust from the
seawater. Provides excellent silencing of exhaust exit
noise and splashing noticed in standard water lift
muffler-alone installations. This kit installation requires
