Re: advise on genset

Love my Northern Lights 6kw. Just freaking love it. I have worked on Onan, Westerbeast, and Kohler and none of those compare IMO. I work, cruise and generate in the USA...

Re: advise on genset

I think the lower reving gensets are the way to go. I've heard a lot of complaints about the higher reving units. The one piece of advice I can offer you by personal experience is: Even though by careful measurement, it looks like you can fit a larger kw generator in a given space, make sure you have PLENTY of room AROUND it to do routine maintenance. The guy I bought my boat from, crammed an 8 kw genset in a 5 kw space. I can barely change the fuel filter and the only way to remove the heat exchanger is to raise the whole genset by crane out of the lazarette and onto the deck. That will be this summer's project.

The generator was not used hard enough and died after only 1100 hours of use. There was no compression in any of the three cylinders and the crankcase was full of diesel fuel. I had the generator removed and am now looking at smaller gensets to replace the Westerbeke.

Thanks for the input from the forum.

IMO, under use wasn't the cause of the failure, something else happened. Under use may cause exhaust elbow clogging, but wouldn't fill the crankcase with fuel. It sounds like poor or no maintenance, even checking the oil before startup would catch a leaking fuel pump putting fuel in the crankcase (gee, this engine is producing it's own oil).
