Looking through the Yamaha brochures online it says on one page "the engine is now aft", or words to that effect, and the engine is a 3GM (27hp). Clearly it was an early model boat I sailed that had a 9 hp 1GM under the forepeak berth. It worked OK though, though if you wanted to get anywhere quickly you were better off under sail except in a flat calm.
I owned a Yamaha 30 in Hong Kong for about 8 years. It had the forward mounted 9hp 1GM engine; supposedly a favourable arrangement under the the then IOR rating rule. I also sailed a 33 and, if my memory serves me correctly, it had a normal aft mounted engine. They are very strongly built boats and last years with little maintenance. Somewhat cramped inside compared with modern yachts of a similar size and being relatively heavy probably slower.
