Right, besides the noise, I don't like that this think can never be below
deck (gasoline). The generator and it's fuel supply always sit at the stern

similar sized diesel system would be welcome.

Well, I can say from experience that you probably do not want an air
cooled diesel generator either. The previous owner of a power boat I
am rebuilding installed one. Noisy, vibrates and makes a nice heater
for the cabin when it is cold. Plus, no emergency shutdowns installed.

The problem with a fixed gen set in a 35 foot boat (I think the OP
said that) is where do you put it? I've seen them installed but
generally it turns out to be a compromise.

I watched them install a BalMar single cylinder diesel, in a 36' Cape Dory.
They put it aft of the engine which made the boat squat in the ster. Not
pretty to look at. The other thing was that if you had to get to the
steering quadrant, you had to unbolt the generator and slide it out into the
pilot berth and then squeeze by it to get to the steering and packing gland.
When the generator was running, you could hardly stand the vibration and
noise down below, but they had air conditioning.

Yes, I hear you. In my case, there's lots of room. Seawing is a 41' Center
Cockpit with a large engine room. Originally there was a generator
installed, but it was dead when I bought the boat & I've removed it and used
the space for a house bank.

That size sailboat usually has such a relatively small engine anyway,
I've often wondered why someone doesn't market a combination primary
propulsion/genset. IOW, one engine that drives both the prop and the
generator. Seems it would help with the space problem as well as
weight distribution.

Oh, like the new Yanmar-set?

From the brief description I believe that the generator described is a
DC generator which in turn drives an inverter to produce AC.
Essentially the same system as the new Honda. If so it should solve a
lot of problems.

That's an interesting product but you can get almost as much power
using a big alternator and an inverter. Add a large battery bank of
400 to 800 Amp Hours and you have a great deal of flexibility. It's
important to get the alternator mounted correctly: Solid mount,
properly aligned, and the right belt(s).

3 or 6 kWH would be a SUPER big alternator, and this thing's only 4"
thick and connects between the engine and transmission.... Sounds like
direct-drive off of the crankshaft, industrial strength components and
a lot of reserve power for a boat. Heck, I think I could run my house
off of that if it weren't 50 Hz. Also suspect their power measurements
are more conservative than the Honda's.

I like the idea better than two engines, one only for the generator,
particularly since I see more problems for generators than primary
engines -- probably due to their low usage.

If I ever have a boat that needs 40 or 55 hp, I believe this might be
on the list of things to consider.

Exactly! ... I think.
Without a picture.... well, the description is less than a thousand
words. But it sounds about like what I was thinking. Smallish engine,
generator lined up behind and on the centerline for balance, spins the
prop or the generator or both, yeah... like that :-)
Nice find :-)
