Golf diesel into yacht info?

hey all

along the lines of the fella wanting to put an air-cooled vw motor in a boat - my father is looking for an alternative (and cheap) motor for a yacht...Linde use golf diesels in fork lifts and they seem like a reliable fuel efficient little beast..

anyway, he's interested in the older motors - without all the electronic gadgets...

what sort of hp do they make?
and in what rev range?
how heavy?
approx dimensions?

if that all checks out does anyone have one they want to get rid off in Brissy/Gold Coast region?

cheers
