Review the jet-propulsion layout of the Mercury 105ELPT, a 105 HP remote outboard using Mercury’s 3.0L inline-four FourStroke powerhead. It can be evaluated for shallow-draft aluminum river boats or jet fishing hulls only when the boat builder specifies jet propulsion, compatible transom structure, remote steering, and sufficient horsepower capacity.

Boat length alone cannot confirm fit, even for similarly styled river-fishing hulls. Actual speed depends on hull form, beam, dry weight, passenger and gear load, jet-intake condition, engine mounting height, trim, current, water depth, and throttle position. Confirm the capacity plate, engine-weight limit, jet-rigging layout, steering components, and remote controls before replacing a propeller outboard.

Key Features of Mercury 105ELPT

- Jet-drive propulsion replaces a conventional propeller gearcase for boats rigged for compatible shallow-water operating conditions.
- The 3.0L inline-four FourStroke powerhead identifies Mercury’s stated engine platform for the 105hp Jet family.
- A 105 HP rating requires a vessel capacity plate and transom rating that support this propulsion output.
- Remote configuration requires compatible steering, throttle, shift, electrical harness, and fuel-system equipment during marine rigging.
- Jet-intake condition affects installed propulsion operation, making inspection relevant before use in shallow-water environments.

Why Choose Mercury 105ELPT

Choose this outboard for a jet-rigged shallow-draft hull, not as a direct replacement for a conventional propeller engine. It suits a buyer who needs a propulsion layout matched to shallow channels or river conditions and can verify the boat’s capacity, transom, intake installation, steering, and controls. Length is only context, while boat-builder approval determines actual compatibility.

- Matches jet-rigged shallow-draft hulls with verified transom and capacity approval.
- Requires intake, remote steering, and control-system compatibility before rigging begins.
- Leaves speed expectations dependent on hull, load, water depth, and setup.

Warranty, Support and Maintenance

For eligible Mercury Jet 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, jet-intake inspection, corrosion-prevention requirements, and maintenance records.
