OB manufacturers build the motor lineups in 'families' of block/frame sizes. In the Tohatsu/Nissan/Mercury 4-stroke line, the 2.5/3.5, 4/5/6, 8/9.8 (merc calls it the 9.9), 15/20, and 25/30 are designed that way. In essence, the smaller hp motor is a de-tuned version of the larger brother. The lines on the Honda were to make raising it an easy deal and will be moved to the Tohatsu. Here the 9.8 HP is mounted on the transom in the stock location. If you want the extra long shaft it is only available in the 9.8 HP model. Both the 8 and 9.8 HP are offered in electric start and in a long shaft model.
