Honda BF100
Brian, I have a 1981 Honda BF100L, Serial number 1300698, and the Shop Manual for it. The manual doesn't list an electric starter for this engine -- only rope pull. It does show an optional vertical pull mechanism that could be purchased and installed on the engine, but mine didn't need it. Maybe later ones had the option of electric start, but I don't know when or if they did. I have saved this engine for a dingy when I get one for my larger boat. This engine is amazing -- has been seized when the water impeller failed, and still starts on the second pull, without burning oil. When it seized, it cooked the plastic oil filler plate and fuel pump spacer, causing major oil leaks, but still got me home between seizing up, cooling down, and starting up again, only to seize up again. Still runs great.
