Yamaha's all-new boats have several new major noteworthy design features. Perhaps the most important is the 72% increase in engine displacement, going from 1052 cc in the old models to 1816 cc in the new 242 and 240 models. Yamaha says that the boat’s performance has improved markedly as a result. Another improvement is the far larger “U”-shaped bow seating area that appears to have all of the room of a pickle fork or deckboat design while still keeping the traditional 20-degree deadrise hull and conventional bow. Yamaha has also improved on their innovative stern seating area in which they have led the whole sportboat industry.
