Engine and steering

Mercury rates full throttle at 5000-5800 RPM for this powerhead, built on the same 3.0-liter SOHC design as the rest of its 150 HP line. Steering options include dual-cable mechanical, hydraulic power steering, or an electro-hydraulic setup for twin-engine installs, and multi-port EFI runs through a SmartCraft-managed ignition. Power trim and tilt range 22 and 73 degrees respectively, and the belt-driven alternator is rated at 756 watts, 60 amps.

Fluids and buying notes

Mercury specifies a minimum of 90 octane unleaded fuel and an NMMA-certified FC-W 25W-40 synthetic blend oil at a 6.3-quart capacity for this engine. The propeller is not included, so budget for one separately, and since this is a used, commercial-grade motor, ask the seller about recorded hours and service history before buying.

Is this compatible with a Big Tiller setup? Yes, in addition to standard remote steering options.

What is the dry weight? 455 lb, which Mercury describes as the lightest model available in this class.
