Mercury 250 Optimax M2

Features

• Large 7.25" diameter pump pushes more water through the pump for greater thrust, superior effeciency, maximum acceleration and ski towing capability.
• 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.
