The Yamato model 302 is a 24.2 cubic inch stock racing engine. Like it's predecessors, this motor was developed specifically for use: in multi-billion dollar pari-mutuel boat racing industry in Japan. These motors are required to run heat after heat, day after day with perfect reliability at racing speeds. Therefore, they have been "over-designed" in relation to the job they perform.
