Mercury 2005 Mercury 125 HP 2-Stroke 20″ Shaft

This 2005 Mercury 125 HP outboard comes used, with the seller describing its condition as like new. It is a two-stroke motor, black in color, carrying a 20-inch shaft and 206 hours on the clock, and it suits owners replacing an aging 125 HP two-stroke on a mid-size runabout, pontoon, or center console already rigged for that shaft length. Setup and what's included The seller describes the engine as serviced and set up to run once mounted, pairing it with its own DTS rigging and gauges rather than leaving the buyer to source a control box separately. It has electric start and power trim, is configured as a remote-steer model rather than a tiller unit, and uses oil injection, so fuel and oil are not mixed by hand before each outing. What to check before buying Measure the boat's transom against the 20-inch shaft before ordering, since the wrong length changes how deep the propeller sits in the water. Confirm the DTS rigging and gauges match the boat's existing dash layout, and because this engine is sold used, ask about recent maintenance and the condition of the water pump impeller and lower unit before running it under load. Owners moving between two-stroke Mercury outboards often find the remote setup familiar, since throttle and shift wiring tends to carry over from one two-stroke to the next. Is this a tiller or remote-steer motor? Remote. It is built for a boat with existing throttle and shift controls, not a tiller handle. Does it need fuel premixed with oil? No, it is oil injected, so the two stay separate rather than mixed by hand each time.
