Goedendag,

ik heb uw advertentie "Yanmar 3GM30 marine engine, can be seen running, without gearbox" gezien en ben geïnteresseerd.
Mijn vragen zijn in het Engels — ik hoop dat dat geen probleem is:

- Is the engine freshwater or raw-water cooled?
- Do you know the approximate engine hours?
- When could I visit to hear it run?

Ik haal zelf op en reis vanuit de regio Kopenhagen — ophalen over de grens is geen probleem.

Met vriendelijke groet
