Are you guys panning this boat because of the Peninsular engine? I agree it is a big negative and probably takes $10-15,000 off the value it would have had with one of the big 4 marine engines.
It sounds like it was recently repowered. I can't imagine why someone would choose a Peninsular unless it was real, real cheap, like $5K.
But having said that, I did a search on boatdiesel and they don't sound that bad. Parts are available everywhere and Peninsular is still in business. Difficult maintenance access no doubt due to all of the marine bits in the way was the only real complaint.
