Soriano du Puy (and more), Deutsches Museum (Munich)
The Deutsches Museum in Munich is heavily populated by technical displays, including a small outboard display. Here are a few nice items:
Photos 1-6: Dr. Robert Richter's step plane with supercharged 4 stroke Soriano outboard. With the quasi-tractor gearcase the rear prop only eats the wake of the forward prop (elementary hydrodynamics suggests that it couldn't work as well as a single prop, but hydrodynamcs is nonlinear so actual tests are useful). Note the automobile steering wheel.
Photo 7: 345 cc/70 hp König. Did anyone get more hp/cc than Dieter König?
Photo 8: Laros 2 stroke, Milano, ca. 1930.
Photo 9: 1996 Evinrude 150 cutaway with direct injection, donated by W. Hellmich of the Provenion company (Munich) that made the Ficht (?) system during 1990-96.
Photo 10: Joe McCauley, Cornelia Küffner, Finn and Hans Küffner-McCauley after a very enjoyable Jan. day at the museum. I've visited the Richter boat every time I've gone there since 1996. Hans and I have a 1981 Evinrude 15, shipped from Houston, that we plan to rebuild completely in our cellar workshop in Austria this winter.
