Details & Inspection Notes
The Mercury 300HP L FourStroke Outboard White is a new V8 on a 20 inch shaft with remote mechanical steering, offered in three white finishes.
Rigging
Remote mechanical steering bolts to a console and cables rather than a tiller, so confirm your boat already carries that rigging, or budget for it, before ordering. The 20 inch shaft is the shortest option in this range, meant for a transom on the shallow side compared with the longer shafts Mercury also offers at 300 horsepower.
Specifications
Weighing 527 lbs dry, this electrically started V8 draws fuel through electronic injection, and power trim and tilt adjusts running angle from a switch instead of a hand lever, useful on an engine this heavy.
Color, inclusions, and warranty
Pick between warm fusion, cold fusion, and pearl fusion, Mercury's three white options for this engine. The engine arrives with its manual, mounting bolts, and a tool kit, backed for 3 years by Mercury's factory warranty. This engine does not include a propeller, so order one to match your boat.
Rigging reminder
Because this is the remote-mechanical version, confirm your existing helm, cables, and control box are compatible before ordering it as a replacement engine.
Which shade runs truest to a typical hull white? Mercury does not rank the three; pick whichever matches your boat most closely. Is a propeller included? No. Is a control box included? No, remote mechanical steering needs a console-mounted control box and cables that are not part of this package.
