The Verner VM 133 is a family of Czech two cylinder, horizontally opposed, four stroke aircraft engines, designed and built by Verner Motor of Šumperk.

[1][2][3] The 133M is based on the earlier Verner 1400 and uses a 12 volt 1000W electric starter and has a 12 volt 160W generator.

It runs on 95 octane automobile fuel or 100LL Avgas.

The recommended time between overhauls is 1000 hours.

[1][2][3][4] The engine was still advertised for sale on the company website in 2013, but by 2015 was no longer listed as available and it is likely that production has ended.
