I'll be glad to supply details. Now one challenge applies two both generators. They were inexpensive. That means that one cannot expect them two be stable, that is deliver a proper 50HZ (60Hz) sinus alternate current. If one chooses an inexpensive generator one must on the other hand have a charger that accepts varying tension (volt) output and a modified sinus curve. And one need a pure sinus-curve inverter that delivers pure sinus wave current to delicate application like computer, TV etc.

One other challenge is that this diesel-generator is quite noisy. So I had do some work two reduce the noise. That is put on suspenders, like the ones one is using on an engine, and I had to improvise a muffler. The dimensions of the tube of the exhaust terminal of the generator do not fit with any standard dimension for tubes, so I had to join an aluminium exhaust-tube into the inside of the diesel-exhaust-tube and fasten it together by cutting open a beer-can as a sheet and roll it around the joint and fasten it with tube clamps. (Like we did in the -60ties with cars when a hole appeared in the exhaust outlet )

Hope this is illustrating:

The price was equivalent to about $ 1500. It came with an electric starter by the way, which is very good for me. That is recommended. A recoil starter on a diesel engine may be a challenge one wants to pass.

The weight is about 70 kg. (150 lbs), so it is wise to make a final decision of where one wants to place it. It really is a little monster to lug about. I have placed it on the aft deck.
