Tohatsu 115HP | MFS115AETL

Push-button starting and remote throttle control come standard on the Tohatsu MFS115AETL, a 115 HP four-stroke built around a 20-inch shaft for boats already wired for console steering rather than a tiller.

What drives the performance

A Variable Idle System lets the operator dial idle speed anywhere from 650 up to 850 RPM, useful for trolling or holding position near a dock, while the 2.08:1 gear ratio favors torque over top speed, useful when a loaded boat needs to get moving. Tohatsu's 4-2-1 performance-tuned exhaust smooths torque delivery across the RPM band, which translates into a quicker hole shot, less drag once the hull is on plane, and an easier run toward top speed.

Charging and upkeep

A high-output 41-amp alternator backs the 12-volt charging system, a detail that matters for boats running fish finders, bilge pumps, or other electronics alongside the motor. A built-in fresh-water flushing port simplifies rinsing the cooling passages after each outing, and the four-cylinder, 1995cc EFI powerhead runs without a carburetor to tune.

What to confirm before ordering

Because this model ships for remote steering, confirm the boat's console and controls are set up to match before ordering rather than assuming a tiller kit is included. Tohatsu backs the engine with a five-year warranty.

Common questions

Can the idle speed be adjusted? Yes, the Variable Idle System covers a 650 to 850 RPM range. Does this model include a tiller handle? No, it is set up for remote mechanical steering.
