The large 21.4 cubic inch displacement powerhead of the Mercury 15hp EFI develops plenty of low-end torque, making it an excellent source of power for medium to larger sized jon boats, skiffs, and inflatables. This 111 lb. 15 HP Mercury outboard motor is equipped with manual start and 15″ short shaft. Mercury outboard engines surpass industry standards and deliver power and fuel economy at a great price. Mercury’s multi-function tiller handle and vibration-absorbing wishbone mounts are just a few of the exclusive features found on Mercury 15hp models.
