Weismann. Known for their transmissions, but they do build outdrives. I get the feeling they know what they are doing....Their tranmissions back in the day had the offshore Zero Defect Skater pretty dialed in, amongst the other race boats, it was impressive.

Here is another product of theirs, counter rotating props, hence a nice option for a single engine engine application. I have no idea what their products cost.
