Inboard engine: 1972 Arona 20hp

Since its launch in 1972 Mizar had 2 engines mounted. the original from the conyplex shipyard was a Volvo MD2B 18hp which history I don't know.
In the late 90's a Lombardini FOCS 25hp was mounted. Although a good engine with a combination of power and lightweight, some parts of it are in aluminium which means a really strict schedule on zincs... which wasn't the case being Mizar abandoned at the buoy for 5 years.. long story short, there isn't an engine on the boat anymore.
So I have been looking on the internet and also thinking what kind of enige I should put on Mizar.
New engines are super expensive and therefore not on the possibility list for the moment.
Old engines are usually very reliable and easy to maintain but that's if previous owners have been taking care of it...
Finally after long weeks spent searching the internet I have found not too far from my home an Italian brand engine called Arona.
The company has shut down in 1983 but apparently these engine are quite good and basic which is what I need.
The model is a AD290 Arona 20hp from 1972. I bought it the same day the advert was posted on the internet. The second hand outboard demand is incredibly high and these engines are sold fast. 

The engine needs some maintenance but kicks on at first attempt and also the alternator works well.
Another plus for these old engines is that the maintenance manuals are still accessible and very well written explaining and picturing all main activities you need to do on it.
more info on these engines can be find on the links of this blog.

Minus points are its weight, almost 200kg, and the fact that spare parts are not so easily accessible but some of them can still be found from main producers (bosch, etc) look here:
