TP-6772 2/14b16 Section 2 Operation
2.2 Marine Inspection
Kohler Co. recommends that all boat owners have their
vessels inspected at the start of each boating season by
the US Coast Guard, the local Coast Guard Auxiliary, or
local state agency.

exhaust system inspected at the start of each boating
season by an authorized Kohlerr distributor/dealer.

2.4 Operation in European Union
Member Countries
This generator set is specifically intended and approved
for operation below the deck in the engine compartment.
Operation above the deck and/or outdoors would
constitute a violation of European Union Directive
2000/14/EC noise emission standard.
2.5 Load Profile
Whenever operating the generator set, Kohler Co.
recommends maintaining the minimum load profile
indicated in Figure 2-1. Maintaining the load profile
prevents corrosion formation on internal engine
components when they’re exposed to the breakdown of
exhaust gases. Extended light loading may result in
engine “wet stacking”.

Figure 2-2 Load Profile
Wet Stacking occurs when water vapor condenses in
the exhaust system. At normal combustion
temperatures, water stays vaporized but at low
combustion temperatures, it condenses back to a liquid.
When running the generator set under normal loads
(30% load or more), diesel exhaust stays hot enough to
prevent water vapor from condensing. At low load
situations, wet stacking can occur.
The operator should perform all of the prestart checks.
Start the generator set according to the starting
procedure in the controller section of this manual. While
the generator set is operating, listen for a
smooth-running engine and visually inspect the
generator set for fluid or exhaust leaks.
