DuroMax 999cc Gas Multi-Purpose Horizontal Shaft Push Button Electric Start Engine

DuroMax 999cc Gas Multi-Purpose Horizontal Shaft Push Button Electric Start Engine

The DuroMax XP35HPE is the most powerful engine in the DuroMax lineup—a 999cc V-Twin, 4-stroke OHV horizontal shaft engine built for projects that don’t politely ask for power… they demand it. With push-button electric start, electronic speed control, and a digital RPM display, it’s made for serious builds like go karts, ATVs, boats, and other custom equipment where “overkill” is just another word for “peace of mind.” It runs on standard 87-octane gasoline and comes equipped with an oil cooler and muffler, so it’s ready to work right out of the gate (and it’s definitely not here to whisper).
