Although the 650 EFI may be small by some standards, it is not small on value. Built as an alternative to factory motors, the 650 contains some of the best parts available. Based on a Dart block, this 540 cu. in. engine is available in any custom color of your choice. Loaded with a multitude of billet accessories & a serpentine accessory drive system, it will stand out in any engine compartment. As with all of our naturally aspirated engines, the 650 comes with a 1 year warranty & may be serviced by any qualified Mercruiser dealer.
