Mechanical and engine room

Main engine is a natural aspirated GM/Detroit Diesel model 6-71, which had Dec 2009: new piston rings and injectors. She will have in March 2011about 6000 hrs on her counter. The main engine rates approx 185 HP (injector type N70) at 1900 rpm and gives a max speed of 10 knts Cruising under power at 1600 rpm the ship will show a speed of approx 8 knts. Good to know there are over a 200.000 of these engines around, so parts and service is easy to find.

The Allison hydraulic gearbox is the model is used on engines up to 350 HP, has a reduction from 3 to 1.

The 14 kW KOHLER generator engine is a YANMAR 4-cilinder turbo charged diesel (11000 hrs/Jan 2010), 26HP at 1500 rpm, with an automatic shut off control in case of low oil pressure or high coolant temp. (gauges are in the pilothouse.) Kohler derated this Yanmar diesel which originally produces of the same engine block, pistons and shaft 55 -77 HP at 3600 rpm.

The cooling system for both engines is identical: raw water, via a strainer, passes a salt water/ coolant heat exchanger and is injected in the engine's exhaust pipe and than runs together with the exhaust glasses all the way aft to the stern waterline. Both engines hardly use any lub oil. The main engine has a oil/ coolant/ exhaust gas alarm plus oil pressure, water and exhaust gas temperature and rpm gauges in the pilot house. All exhaust piping and hoses of both engines are complete, from engine to stern, renewed with DUNLOP marine- exhaust flex hose in 1995. Both exhaust lines have vented anti sifons-loopes, and big shut- off valves. There is a steel 100 liter lub oil storage tank and transfer to engine room

Water and pump systems Drinking water from 2x100 gal new epoxy tanks to 40 psi automatic switched pump, with accumulator tank, into ships plumbing system and a special faucet in the galley has a in line carbon filter for excellent drinking water. Vantage Marine water maker (15 gallon per hour) is equipped with flow indicators and U.V sterilizer. (All renewed in 2003) This sterilizer is equipped with filters and is also to be used to make water that's taken in from shore safe drinkable. 2 electric heads, sweet water flushed, all showers and sinks drain in 300 gal waste tank, which has 2 parallel-installed pumps (24V).

Bilge Pumps
The three (forward, engine room and aft) bilge sections have all a separate electrical bilge pumps with alarms and a extra mechanical Jabsco bilge pump system driven from main engine with manual clutch is operated with fast ball valves in engine room. A fifth automatic switched and separately wired bilge pump is a 3700 gall Rule pump. Main engine raw water cooling pump can be operated as emergency bilge pump. When hard comes to hard: Honda gasoline 100 gal/min pump is standby in port wing.
