ENGINES & HYDRAULICS:

Main Engine (3,437 hours): John Deere Model 6081 AFM: Main propulsion is supplied by a John Deere Model 6081 AFM w/ M3 rating @ 330HP @ 2,200 rpm, coupled to a ZF #ZFW325, 3.958:1 reduction transmission, in turn coupled to a 3″ Aquamet drive shaft (an upgrade from standard A17) on which is mounted a 5-bladed, 42″/28.5″ pitch bronze propeller. This transmission reduction allows the propeller to turn slowly, greatly reducing noise and vibration. The PYI dripless Shaft Seal helps to eliminate water in the bilge (100% water tight) and reduces wear on the propeller shaft. The engine is keel-cooled, with a dry exhaust with an in-line muffler, a signature design element of most Nordhavns, which eliminates the need for a large through-hull and raw water pump, greatly reducing the risk of failure at sea. A Spurs Marine line cutter is installed on the main shaft, just forward of the propeller.

Wing Engine (317 hours): John Deere 4045 DFM75: Auxiliary propulsion is supplied by a John Deere 4045 DFM70 HE 24V “wing engine”: 80 hp High Output Heat Exchanger Cooling with a ZF 631V 2.477:1 ratio “V-Drive” transmission with Morse control cables. Gori folding propeller, 3 blade (24″ diameter x 19″ pitch). Shaft is 1.5″ diameter Aquamet 22 (an upgrade from standard A17) and is tapered at the propeller end A rubber cutlass stern bearing is encased in a housing supported by a strut attached to the hull.

Hydraulic Systems: ABT-TRAC: Ithaka is equipped with ABT-TRAC’S integrated hydraulics system that is powered by quiet, high efficiency hydraulic piston pumps separately driven by the main engine, the wing engine, or a PTO (Power Take Off) pump on the 25 kW generator. These pumps support various systems:

• Anchor Wash Pacer Pump (SE2IBLHYC), located in forward equipment area, delivers 180 gpm

• Bow and Stern Thrusters ABT-TRAC twin, counter-rotating propellers, are installed in both the bow and the stern.

• Emergency Bilge Pump Pacer Pump (SE2IBLHYC), located in Engine Room, delivers 180 gpm
