Mercury 105HP 105ELPT Jet Drive Outboard – 20″ Shaft
Designed with 105 horsepower and jet-drive propulsion, the Mercury 105ELPT uses a 20-inch shaft for compatible installations. Jet drive reduces exposed propeller hardware, supporting shallow-water operation, while proper shaft matching helps maintain water intake and steering control.

Common Question of Mercury 105ELPT
Is 105ELPT a jet drive?
Yes. The supplied title identifies Mercury 105ELPT as a jet-drive outboard. Jet propulsion uses an intake, pump, impeller, and steering nozzle rather than an exposed propeller. Verify the exact horsepower, fuel system, controls, and regional specification before purchase because the model designation and listed 105-horsepower rating should match manufacturer documentation.
What transom fits its shaft?
A 20-inch transom is the intended match for this Mercury jet-drive configuration. Measure the hull and verify intake clearance before installation. Correct mounting supports water flow, cooling, thrust delivery, steering response, and shallow-water operation. Keep sand, gravel, weeds, and debris away from the intake during use of this ready to bolt marine package.
Does it use fuel injection?
Confirm the exact Mercury model specification before making an EFI claim. The supplied title does not identify fuel injection, so buyers should verify fuel-system details, horsepower, controls, wiring, battery requirements, and jet-drive components with the seller. Accurate documentation prevents incorrect fitment and supports reliable operation of this high performance outboard motor.
