Rubber-isolated engine mounting system isolates engine vibrations to give you a smooth, comfortable ride and never requires adjustments or alignment. Unique, multi-step painting process includes chemical treatment, EDP and chrome epoxy primers and abrasion resistant acrylic paint baked to a hard, corrosion-resistant finish. Stainless steel impeller with variable pitch provides superior propulsive efficiency, performance and durability. Low maintenance pump requires only annual lubrication maintenance on all pump bearings, no need to disassemble pump parts to change oil. SmartCraft compatible engine allows for up-to-the-second engine gauge information and gives advanced warning of possible problems. Automatic bilge siphon system keeps your engine compartment dry whenever the engine is running, even when the electric bilge pump fails to operate. High-thrust, dual outlet reverse gate provides unmatched reverse thrust for backing off trailers and maneuverability when backing up. Fully integrated, easy-to-use engine flush port helps keep cooling system clean from saltwater corrosion and debris.
