: Scoots me along at just under hullspeed. Last surveyor said it was propped just fine. What RPM are you turning on that Perkins, Doug. Lionheart has a 4-108 I got from a guy on this newsgroup in NC for $1200. In spite of the boatyard's screwup flooding her exhaust and crankcase with seawater with a dripless packing water injection line, she's a great engine. Our econocruise is also very easy to get near hull speed on the Amel Sharki 41 ketch at around 2200 RPM, but she's nearly as fast at 1800. There's a 120A house alternator mounted to port and the engine has a 90A alternator on its bracket for the starting battery for some silly reason I have yet to figure out. The new fridge is 12/120V so we took away all the car air conditioner parts of the old French fridge/freezer combo. The original Perkins that came with the boat ran just fine, even though the hourmeter read over 7000 hours! Engine shop said it was still usable so it's in the captain's garage in Atlanta, our spares repository of used parts. Simply an amazing engine.....by anyone's standards. |

The calibration of the tach is off because the alternator is not stock. When we first bought the boat I measured the actual RPM and made a graph to convert from indicated to actual. Converting the proper cruising RPM to the indicated gives 2500 so that is where we run unless we need some extra. I've forgotten what the actuals are. 1800 sems to stick in my mind but I'd have to go look it up. Doug |

Lionheart has 90 gallons of diesel in the tank that's the starboard seat in the center cockpit. It's amazing how long that lasts under power. |

Great cruising range but having that much fuel when one only consumes 1 GPH has it drawbacks. Doug |

Doug Fuel polishing is probably an issue, mostly ignored by sailors until it's clogged the injectors or at least the filters. It always disturbs me how so many sailors will just leave the tanks half empty all the time, instead of topping them off before docking. Being down a gallon or two is probably ok, but the condensation in a half-empty fuel tank of any size is just awful here in Charleston. It's just laziness. All those that have half empty fuel tanks all have plenty of money to fill them. http://www.gulfcoastfilters.com/fuel_polishing.htm |
