Southeastern Power Products KK3-9.5 Marine Diesel Generator – Keel Cooled

Description

Eliminate raw seawater pump failure using the Southeastern Power Products KK3-9.5 Marine Generator, designed specifically for shallow-water workboats and commercial fishing vessels. Operating at 1800 RPM, this keel-cooled diesel plant supplies 9.5 kW continuous output and 11.5 kVA surge capacity at 120V and 240V 60Hz, powering walk-in galley freezers, deck lighting, and navigation switchboards without raw-water ingestion.

A water-cooled three-cylinder Kubota diesel engine drives a heavy four-pole synchronous alternator, mounted on a coated steel base pan fitted with heavy rubber isolation mounts. Stator assemblies incorporate 100 percent copper windings with Class H marine varnish to prevent insulation degradation from ocean humidity. Weighing 440 lbs dry, the generator housing measures 34.0 inches long by 20.5 inches wide by 24.5 inches high.

Key Features of Southeastern Power Products KK3-9.5

Vessel operators who buy Southeastern Power Products KK3-9.5 marine generator units gain keel-cooled commercial power equipment built to operate without raw seawater pumps. Closed-loop keel cooling circulates engine coolant through exterior hull pipes, eliminating silt erosion and clogged sea strainer failures in muddy shallows.

• 9.5 kW continuous electrical output powers galley cooktops, water heaters, and vessel battery chargers on long runs.
• 11.5 kVA surge capacity starts inductive marine air conditioning pumps and deep freezer compressors without stalling.
• Keel-cooled closed loop design eliminates raw-water impellers, raw hoses, and seawater heat exchanger maintenance.
• Kubota three-cylinder diesel block provides smooth mechanical balance and low rotational vibration.
• KK3-9.5 commercial marine construction utilizes cast-iron cylinder liners for extended engine operational life.
• Brushless synchronous alternator eliminates carbon brushes and slip rings to minimize maintenance requirements.
• Elastomeric vibration dampening mounts decouple engine vibrations from commercial aluminum and steel vessel hulls.
• Automated emergency safety sensors shut down fuel delivery upon high engine coolant temperature or low oil pressure.

Dynamic Step Load Transient Tolerances

Emitting 56 dB(A) at 23 feet inside an optional sound capsule, this generator prevents noise fatigue across commercial vessel wheelhouses. An integrated electronic automatic voltage regulator maintains output voltage within 2 percent of 120V and 240V standards at 60 Hz during heavy motor starts. Diesel fuel burn measures 0.65 GPH at 50 percent load, providing high operational fuel economy.

Keel Tube Plumbing Stringer Fitment

Secure the steel mounting pan to vessel engine beds, ensuring 12 inches of perimeter clearance for routine servicing. Route closed-loop coolant pipes through the vessel hull bottom to external keel cooler channels, installing a dry exhaust silencer overhead. The isolated DC grounding circuit protects aluminum and steel hulls from stray-current galvanic corrosion.

Routine Handling Mechanical Service Tasks

Single-side maintenance engineering places all primary checkpoints on one accessible face for rapid routine inspections. This keel-cooled marine generator is not engineered for wet exhaust marine installations lacking exterior keel coolers, nor for gasoline vapor spaces lacking spark-proof ratings.

• Inspect coolant header tank expansion levels and check engine oil before each shift.
• Renew engine oil and replace primary fuel filters every 100 runtime hours.
• Check alternator winding insulation resistance and check valve lash every 250 runtime hours.
