Overview

Mercury's Optimax was the two-stroke that changed minds: direct fuel injection (DFI) firing fuel straight into the combustion chamber for more power on less fuel, less smoke than old-school 2-strokes, and throttle response that jumps.

This 2009 75HP Optimax (serial 1B747590, model 75ELPTO) shows only 194 original hours and backs it up with numbers: 130 PSI compression on all cylinders, strong and even. It's been recently serviced with brand-new trim ram seals, and comes as a complete package — stainless steel propeller, gauges, control box, and control cables. Photographed as offered, including the serial plate.

What’s included

• Stainless steel propeller
• Gauges
• Control box
• Control cables

Ideal for

Bay boats, skiffs, and pontoons rated for 75 HP — buyers who want 2-stroke punch with modern fuel efficiency.

Compatibility notes

• Confirm your boat’s capacity plate: never exceed the maximum rated horsepower.
• Match shaft length to your transom height so the anti-ventilation plate runs at the correct depth.
• Confirm your transom and hull can support the engine’s weight.
• Controls, cables, gauges, steering components, and propellers are not included unless the listing states otherwise — we verify rigging compatibility with your boat before you buy.
