Umm... You are aware that this is a sailing site, not a power boat site? A Colvic Sunquest, last I checked was a motoryacht, not a sailboat.

That said, it would help if you said what size genset you were looking for, and what your budget for purchasing it was. If you really want to stay with Vetus....just buy what was previously aboard the boat. That would greatly simplifiy installation.
