7.5 HP 29 pound air cooled 2 stroke outboards. These motors are less than half the weight of 6 HP motors. They were built in Newport Beach California between 1967 and 1971. One motor runs and was bought from a collector in Michigan. The other came from Pennsylvania. I planned on using one on my dingy and having a spare. I bought a dingy that is only rated for 5 HP. They have 1 cylinder Tecumseh power heads.
