The 22ft long, full height engine room in the Fleming 75 is spacious, brightly lit and laid out with easy access to all equipment. There are even lights illuminating the drip pans under the engines. Stainless steel overhead handrails run the full length of the engineroom. The overhead is up to 8" thick, filled with sound insulation, and has sufficient stiffness to eliminate the need for support posts which, when installed, can transmit vibration to the overhead. A workbench with drawers, stainless work surface and Swiss-made stainless and alloy vice are standard. Floorboards are dressed with checkerplate-patterned Lonseal for appearance and sound attenuation. Engine room is lined with reflective alloy pegboard for easy maintenance. The engine-room access door is internally insulated, submarine type with gasket, double latch and inspection window.
The two main fuel tanks divide the engine room from the accommodation and total 2,500 US gals. Two auxiliary wing tanks bring the total fuel capacity up to 3,000 gallons. The fuel tanks are located on the longitudinal center of gravity so the trim of the Fleming does not change as fuel is consumed. Sight gages show the height of the fuel in every tank and capacitance probes display the contents, in either gallons and percentage, on a readout in the pilothouse. Twin Racor filters with vacuum gages, change-over valves and stainless steel drip trays are standard as is a fuel transfer pump, with filter and counter, which can be used to transfer fuel between tanks. Fuel selector panels provide easy selection for supply and return to and from main engines and generators. Storage bins for spares are provided above the side tanks.
Fire suppression and shutdown system is by Seafire using FM-200 gas which is more expensive but safer than that mandated by US regulations. Intake air is drawn in from around cockpit rather than the outside of the hull where it is laden with salt. Automatic baffles close off the ventilation ducts at aft end of engine room. The fire system is equipped with siren and warning light and has a manual pull operated from the aft deck.
Naturally the main engines are the most prominent items of equipment in the engineroom. Standard engines are Caterpillar 3406, 800 hp, with optional Caterpillar 3412E 1,400 hp. There is good access around both types of engine and both are fitted with additional 100 amp alternators with volt and ammeters and remote mounted regulator. Oversize raw water intake ball valves and sea strainers are conveniently placed.
Huge Aquadrives (the largest in the range) isolate the engines from the shafts and permit the use of soft mounts, matched to the vibration characteristics of the engine, which reduce noise and vibration transmitted to the hull. The shaft couplings have protective covers for safety. There is easy access to the shaft logs which are bronze with dripless packing.
Standard generators are two 27.5 KW Onan in soundshields. Offered as an option are 32KW Northern Lights housed in custom soundshields of mirror-finish stainless steel. Generator exhausts pass through waterdrop mufflers to reduce exhaust noise to a whisper. Special attention has also been paid to the main engine exhaust system which uses all USA-made components and has been designed to keep the boat as quiet and free from vibration as possible.
Variable displacement pumps on both engines power the American Bowthruster centralized hydraulic system thus maintaining stabilizing and bowthruster operations even when running on one engine. Stabilizer actuators are readily accessible forward of the wing tanks and the hydraulic reservoir is easy to reach on the aft bulkhead. A hydraulically-driven Pacer emergency bilge pump with 2" suction is optional.
Hynautic power steering is driven by separate pumps on each engine to maintain power steering from either engine.
95 US gal oil tanks to port and starboard provide storage of clean and dirty lube oil. Tanks are connected to two oil change systems.
16,000 BTU airconditioning is offered as an option.
Lazarette
Foldaway ladders through two lockable cockpit hatches provide convenient access into the lazarette which contains the watertanks, Cablemasters with cable bins port and starboard, freshwater pumps, steering gear and water heater for crew's quarters. All equipment is located for easy access and leaving ample space for storage.
