The most integrated system, now below deck. A drive-to-throttle solution designed for boat builders, optimised for serious operators. 115hp inboard motorskid, 400V battery, controls and fast charging, specified and supported as one unit.
The 115E Inboard is a complete electric motorskid: motor, inverter, cooling and 12V supply on one 120kg assembly, built to take the place of a fuel engine ahead of a standard sterndrive.
Engineered around standard fuel engine sterndrives, so the hull, transom and lower unit stay as they are. One skid replaces the engine; the drive stays.
92kW at the motor shaft all day, with 161hp (120kW) on tap for the hole shot, and 270Nm of peak torque from zero RPM, up to 5,500 RPM.
IP67 throughout, closed-loop liquid cooling, electric throttle, a 7" HD display and LTE, Bluetooth and Wi-Fi, with a built-in 12V supply (2.5kW continuous, 3kW peak) for the boat's house loads.

Compare what a fuel sterndrive burns in a year against charging a 115E Inboard. Adjust the numbers to match how you boat.
Fuel and energy costs only — excludes oil, winterisation, and engine maintenance, where electric typically saves further. Defaults compare both drives doing the same work over 1,000 hours a year, a commercial reference: ~5 gal/hr for a 115hp-class fuel sterndrive, which is about 38kW at the propeller, and ~42kW drawn from the battery for the 115E Inboard. Charging efficiency of 88% is measured from the meter to the battery and includes the charger and on-board loads, so each hour on the water uses about 48kWh from the grid. The saving depends on how you charge: public DC fast charging costs about three times as much as the electricity price shown. Without a zip code the calculator starts from $6.00/gal at the fuel dock and $4.00/gal at the road pump. With a zip code it loads statewide averages, AAA road fuel (July 2026) and EIA residential electricity (March 2026), and adds $1.60/gal at the fuel dock — posted dock prices sampled in July 2026 ran $1.20/gal above road averages on Long Island Sound and $1.94/gal above on Florida's Gulf Coast. Marina shore power and commercial or time-of-use rates are often below the residential average shown. Edit any field to match your actual costs. Estimates, not quotes.
