DuroMax XP23HPE 713cc V-Twin Electric Start Engine

DuroMax XP23HPE 713cc V-Twin Electric Start Engine

The DuroMax XP23HPE is the original heavy-hitter in DuroMax’s premium V-Twin lineup—a 713cc 4-stroke OHV horizontal shaft engine built for projects that need serious power without messing around. It’s a strong fit for go karts, ATVs, boats, and other heavy-duty builds, and it adds convenience with key-switch electric start (because yanking a recoil cord on a big engine is a great workout… but not always the one you want). It’s also EPA and CARB approved for mandated-use compliance—so it can be both powerful and polite.
