    Generator Replacement / Galley Hatch question

    My next project is going to be to replace the original Kohler (Perkins) generator in my 1983 53 ED MY. I know this has been discussed in some old threads but I have a couple of 'simple' questions:

    1) I'm a fan of Northern Lights (20 KW) from other boats I've owned. Is there anything better these days?

    2) I know the process of removing the old Kohler is not easy. I've heard of people adding a large port to the ceiling of their galley to allow easier removal and replacement of the generator. (Rather than breaking things up and trying to get them down the circular stairs to the galley). Any comments on adding such a port? Any recommendations on size/brand for such a product. I do like the idea of letting some more natural light into the galley.

    Thanks so much

    Scarlett either did this or it was done prior. I’ll let him chime in. I’ve seen photos, the extra light in the galley is amazing.

    I ve put 8000 each on a pair of 2003 Lugger powered NL20. Nothing beats them. In all these hours I only did raw water pumps 3 times, 1 injector pump, 1 circulation pump and two motor mounts. Never had to replace a single sensor. In other words one circulation pump,one injector pump and all injectors were still going at 10K

    That s it. And they were still going strong at 10k hours when the boat was sold.

    In the last two years and 2000 hours each on a pair of 2009 Oman 27.5 I ve already done 2 water pump,3 oil press senders, 2 water flow sensors, 1 injection pump


    As to going their the roof it s a lot easier and since you likely have a sunpad covering the area it doesn’t matter if a seam is visible

    My home standby generator is a NL 16kW industrial set- basically the same one on a skid or tank. If there is a better genset out there than a NL, I don't know what it might be. They are VERY reliable and very well made. I have one on my boat, and one at home. Wouldn't have anything else.

    I just put in a 15kw. I cut a hole in the deck and used a crane to hoist out the old and install the new. I redesigned the floor hatch larger for future access. The upper deck is none skid and will have sun pad cushions so cutting a hole seamed better the disassembling a new unit and voiding the warranty

    I am a fan of Northern Lights and have one in my boat. If I was going to replace a generator today I would buy it from Mer Equipment. http://www.merequipment.com/products...enerators.aspx) in Seattle They make Bollard commercial grade, continuous duty generators that are used in offshore fishing fleets. Extremely reliable, easy to work on, cheap parts, and are rated to run 20,000 - 50,000 hours between overhauls. Nothing else out there will last as long. In the pursuit of technology today's marine generators have incorporated a lot of unnecessary crap in their design which include a lot of guaranteed to fail circuit boards and displays that serve no real purpose and cost a fortune. Bollard generators are made to run continuously to power ice machines and other equipment on commercial boats and are only shut down for oil and filter changes and have a history of excellent reliability.

    The 15 KW Onan that I removed from our 53’ went out the forward hatch after removing accessories from it. 15 KW Phazor went in the same way. Idont know where you are located but I still have the trolley and A frame set up that I made to do this. I have loaned it to two other Hatteras owners to replace their units. I am in Pennsylvania.

    When we replaced the 15K Onan on our 48 LRC the installer split the engine from the generating side and it easily came through the hatch.

    This is exactly how I did my generator swap.

    In my 61 MY the second old 20kva Kohler needs to be removed. I can see how to raise it from the genset room to the first level, but can not work out how to get it into the forward cabin to crane out via the hatch. What bracketing or frames is used?

    Does anyone have an explanation or photos please?
