Thanks all for the answer
Weight is not a problem, it will be in a new steel motorsailer
46 ft, 28.000 kgs, (56.000lbs)...
I found lighter diesel but all air cooled, it's very hard to find small water cooled diesel (any idea, advice on brand? links?)
Mounted in the engine room, in the bilge
, no problem for space, but honestly i didn't thought about the heat from the exhaust manifold; for sure covered with heat protection and what if i connect it directly to the exhaust system of the main engine (dry exhaust, it would work),
About the reliability
, i've read that sometimes have problem on starting motor
, but for all the rest they are bulletproof, used for years no stop in small tractor in the farm in china
and all the asia
...it's 1 liter for 13 hp, low revving...Less sprinted than any heavy duty engine
For sure i will buy some resplacement parts
with the engine...
I would want it because i don't want to run the main engine, without pratically any load on it, maybe for a pair of hours every 2-3 days, if not more, just to recharge the battery with a bigger alternator...
The use would be full time liveaboard
, with everything, from air conditioning
, to induction coocking, washing
machine, wife's hair dryer
I already included 2x 400 watt wind generator
and 4 x 250 watt photovoltaic panels
; i don't want to waste diesel (especially here in italy
where is about 1,5 euro/liter, so no webasto) but for example during winter when at 4 pm is dark and no wind
, you need a hot shower
, a warm place, than 2 seabass in the oven
(30 minutes at 2000watt;D)...Heat and energy in just one machine, especially to do not need to produce heat with electricity...
8 x12 v 200 amp pb battery in parallel series, 24 v 800 amp at 19,2 kwh, with pure sine wave 230v ac inverter
..No problem even with 2 x 200 amp alternator...
