OK, I have been in the generator end business for over two decades, and have sold thousands of Marathon Generator ends.

Go with the larger generator end. Always go with the larger generator end.

The reason is that heat, over time is what kills generator ends (any brand). A larger generator end will produce less heat for a given load.

This is no secret in the generator end business. We actually specify generator ends based on heat.

Great example..

Lets say a customer needs a X KW generator end on a certain frame size (diamater)

We can meet that application with several generator ends based on the tolerance for heat.

Again...Always go with a oversized generator end. Less heat = longer life.

Thanks Kevin from me too. I was about to deploy one of those head banging emojis.

An update. Iím taking the Northern Lights Zoom course, taught by Bob Senter. I asked what was the difference in the generator heads In the M673L3G and the M673LD3G and he said they both have the identical engine and the identical generator heads. He said the 6kw ďpunches way above its weightĒ. His exact words.

So I presume they accomplish the additional 1kw electronically some how.

FF is spot on. I would listen to him. Bob Sertner @ Northern Lights just had this same question put to him yesterday on a zoom class call and he said for $200 more, go with 6K. And I trust Bob. FYI, I got a 8k and am happy with it.

Sizing a Genny based on requirements.

Yes, that was me! Itís not $200 more. Itís $500. Plus exchange duty and taxes.

So we are basically a DC boat. I had trouble getting enough load on a 4.2 KW Genny. And while FF is spot on, I donít have any of those induction loads installed in my boat.

The unit was purchased several days ago. I have already exceeded my budget and what I can realistically afford. Same engine. Same generator head. And if the 6 kw was punching way above its weight, the 5 kw should also be doing the same.

Keep in mind, with the 2 units having the same engine, a 2kw load, for example, is the same for either unit. So the 6kw isn't any more of an under-loading concern than the 5kw.
