Details & Inspection Notes

The Mercury 300HP XL FourStroke Outboard White combines remote mechanical steering with three available white finishes.

Rigging and fit

Remote mechanical steering mounts to a console with cables rather than a tiller handle. Mercury lists this as the X-long shaft length in the range; confirm the precise figure with us ahead of ordering, since it did not print cleanly for this particular unit.

Specifications

The powerhead is electric-start and fuel-injected, weighing 527 lbs dry; because power trim and tilt is standard equipment, running angle adjusts electrically rather than by hand on this heavy a motor.

Color, inclusions, and warranty

Choose from warm fusion, cold fusion, or pearl fusion, Mercury's three white finishes for this engine. Along with the manual, Mercury includes mounting hardware and a tool kit, under a 3-year factory warranty. This one does not come with a propeller, so select one to match your boat and typical load.

Rigging reminder

Since this is the remote-mechanical version, double-check your existing cables, control box, and helm layout are compatible before treating it as a drop-in replacement.

Can I order a non-white version of this rigging? Yes, Mercury also lists this same shaft and steering combination without the white finish.

Running in

Vary throttle through the first several hours rather than holding one steady speed, which is Mercury's usual guidance for seating rings and bearings on a new V8.

Startup & Installation Checklist

  • Inspect all external gaskets, seals, spark plugs and timing components prior to installation.
  • Refill engine oil, transmission gear oil and coolant to manufacturer-specified capacities before initial cranking.
  • Prime the lubrication system and verify ECU wiring pinouts, sensors, and ground connections.
  • Startup warranty covers internal lubricated components, cylinder heads, and engine block for 30 days from delivery.
