motor, that's about it.

The Volvo-Penta seems to have been a more or less identical successor to a
Monark and/or Crescent and/or Archimedes model, and maybe comeone can
support me in finding some technical documentation.
Any sort of Owners Manual, Service-, Repair- or Workshop Manual, or however
they called it at the time would be very welcome in order to prolong the
devices life, and in doing so it might drive my boat for some more years to
come.
I have posted this question in other boating related groups but
unfortunately to no avail, so I turn to a bit broader audience.

With my sincerest apologies for bothering all of you with my humble request,

Best regards,

Harm
