I use the IO-360M1A & B 180hp Lycoming engine. It uses the same sump as the 200hp model but has the lighter parallel cylinders but still is 360 cu in. The M1B puts out close to 190 hp because of the cold air induction sump and is 30lbs lighter than the IO-360A1A 200hp. The M1B is a new certified engine from Lycoming in 2002 and comes under new FAA rules that state that the engine has to put out 5% greater hp than published so it can maintain the rated hp thru it’s 2000 hr TBO. So it’s published hp is 180 but on the dyno it shows about 190hp
