My answer to your question would a resolute: absolutely no way!. Go solar panels; reliable and almost maintenance free. The dream piece of kit on a boat. Kyocera is supposed to be the best technology at this point in time. Will usually power everything on your boat, if you don't have 'the Mother of all aircon units'.

I have a Fischer Panda 4.5 and it is the biggest source of problems I have aboard, bar none. It is extremely heavy on maintenance and it breaks down almost all the time. Now this is clearly due in part to a lack of maintenance of the previous owner and it has corrosion problems. But the source of most of those problems are actually due to a crap design, not necessarily lack of tlc. Let me just give you one example (of a long, long list) of design problems of this genset:

You are expected to change oil and clean the filter every 50 hrs of operation. The oil filter (or actually a strainer) sits underneath the unit. Therefore, to clean the filter you have to first lift up the genset. This is operation is described in detail in the manual; the order in which you have to detach all the electric cables and the cooling water hoses before you lift up the unit. Now, we are talking about a 110 kilos unit that is usually deployed in a very cramped space on a boat. It cannot easily be 'lifted up'. You would think that the genius that wrote that part of the manual (in normal German 'grundlichkeit') would have stopped and thought: 'hang on a minute; that does not sound very smart. Maybe we should re-engineer this thing so that an oil change will be a bit easier?' But noooooo; this is an engineering equivalent to the Edsel.

If you get the idea that I do not like Fischer Panda; you are correct. Get solar panels and enjoy life.
