Mercury 115ECXLPT 115HP Outboard – 25in Shaft, Counter Rotation, EFI

Description

With a 25-inch shaft and counter-rotating configuration, the Mercury 115ECXLPT can be evaluated for a twin-engine center console, offshore fishing hull, or larger recreational boat only when the builder’s rigging plan assigns counter rotation at that engine position. Its EFI system and remote layout require compatible controls, steering, electrical, and fuel-system equipment.

A 20 to 26 foot twin-hull length range, if considered during shopping, is market context rather than a fit guarantee. Actual speed depends on hull form, beam, loaded weight, engine spacing, propeller direction, pitch, mounting height, trim, sea state, and operating RPM. Confirm port or starboard assignment, transom height, capacity plate, engine-weight limit, and steering loads before installation.

Key Features of Mercury 115ECXLPT

• Counter rotation supports designated multi-engine positions requiring matched propeller direction and approved rigging assignment during installation.
• The 25-inch shaft requires extra-long transom geometry verified against boat-builder and Mercury rigging documentation.
• Electronic fuel injection identifies the documented fuel-delivery system for this Mercury 115 HP outboard configuration.
• A 115 HP rating requires a vessel capacity plate that permits the installed engine output.
• Remote operation requires compatible steering, controls, gauges, electrical harnesses, battery capacity, and fuel-system components.

Why Choose Mercury 115ECXLPT

Choose this model only when a twin-engine hull requires a counter-rotating outboard at a designated position and a 25-inch shaft at the transom. It is not an interchangeable substitute for a standard-rotation 115 HP engine. Correct selection depends on the builder’s rigging plan, engine spacing, steering geometry, propeller assignment, vessel capacity, and serial-number-confirmed installation components.

• Matches twin-engine layouts requiring counter rotation at a defined engine position.
• Requires extra-long transom, propeller direction, and steering-layout verification before purchase.
• Uses complete vessel setup, not length or horsepower, for speed expectations.

Warranty, Support and Maintenance

For eligible Mercury FourStroke outboards used for pleasure purposes in the United States, Mercury lists a 3-Year Limited Warranty and 3-Year Corrosion Warranty. Commercial use receives a 1-Year Limited Warranty without corrosion coverage. Eligibility depends on current Mercury terms, registration, and actual use classification. Follow the applicable Operation, Maintenance and Warranty manual for scheduled service, corrosion-prevention measures, gearcase checks, and maintenance records.
