Using a 25-inch shaft, the Mercury 115EXLPT is a 115 HP EFI outboard for boats whose manufacturer specifies an extra-long transom. It may be evaluated for center consoles, cabin boats, pontoons, bay boats, or fishing hulls only when the capacity plate, installed engine-weight limit, remote steering, fuel system, and Mercury rigging specifications support this exact engine configuration.

A 19 to 24 foot length range can be used only as shopping context, not as a fit rule for every boat in that class. Speed changes with hull shape, beam, dry weight, passenger and equipment load, propeller selection, engine mounting height, trim, water conditions, and RPM. Confirm transom measurement and serial-number-specific rigging data before ordering accessories or scheduling installation.

Key Features of Mercury 115EXLPT

- The 25-inch shaft requires a compatible extra-long transom and verified engine-height arrangement during marine rigging.
- Electronic fuel injection identifies the documented fuel-delivery system for this Mercury 115 HP outboard model.
- A 115 HP rating requires confirmation that the vessel capacity plate permits the installed engine output.
- Remote rigging requires matched steering, controls, gauges, electrical harnesses, and fuel-system components before commissioning.
- Serial-number documentation identifies compatible rigging parts and should guide accessory selection before engine installation.

Why Choose Mercury 115EXLPT

Choose this engine when the vessel has a builder-specified 25-inch transom and an approved capacity for a 115 HP outboard. It can be considered for certain center-console, pontoon, cabin, bay, and fishing hulls, but final compatibility depends on their individual design. Confirm transom height, engine weight, steering capacity, propeller selection, and remote rigging before treating this configuration as a repower option.

- Matches approved vessels requiring an extra-long 25-inch shaft configuration.
- Requires transom, capacity, steering, fuel, and remote-rigging verification before purchase.
- Connects actual speed to hull geometry, load, propeller, mounting, and water conditions.
