Both the Honda and Yamaha are direct drive. Or are you talking about the camshaft? Those "life" ratings aren't engine life ratings at all, but are ratings for how long the engine stays in compliance with a certain level of emissions. AFAIK Yamaha has chosen to test to the highest possible rating, and Honda hasn't. Doesn't have anything to do with how long the engine lasts.
Some other specifics I found were that Hondas are belt driven versus the gear driven Yamaha. Also, the engine life hour rating for this model is higher than competitor motors.
