Details & Inspection Notes

The Mercury 300HP L FourStroke Outboard DTS White combines the 20 inch shaft with digital throttle and shift control, offering three different white finishes to choose from.

Shaft and controls

DTS swaps cables for an electronic throttle and shift system, which only works with a matching helm, unlike the cable-operated remote-mechanical setup Mercury also builds on this same 20 inch shaft length. Check your transom height against that shaft before ordering, since it is the shortest option in this 300 horsepower range.

Specifications

This 527 lb V8 starts electrically and runs on electronic fuel injection; power trim and tilt is standard, so running angle shifts from a switch rather than a hand lever.

Color, inclusions, and warranty

The white finish comes in three Mercury tones: warm fusion, cold fusion, and pearl fusion, letting you pick a shade close to your hull rather than a single stock white. Mercury includes mounting hardware and a basic tool kit with the manual, under 3 years of factory coverage. A propeller is not part of this package; order one to fit your boat.

Why pick a tone

Matching the hull is really the only reason to choose one white over another, since all three perform identically on the water.

Which tone should I pick? Whichever is closest to your boat's existing finish; mechanically the three are identical. Does the finish affect performance? No, color has no effect on power or handling; it is a cosmetic choice only.
