I found a ~2006 TT 61" deck, 478 hours with a 23 HP Kawasaki Liquid Cooled FD671D engine for $4300. Is that enough engine? Is this a ok deal or great deal? The engine seems awfully small compared to current offerings. Engine specs say the displacement is 745cc which is the same displacement as the 27HP Kawi liquid cooled. The 23 has roughly 1.5 less foot pounds of torque coming in at 41.4 at 2400 RPM. What are your thoughts?
