Public comments

My research has shown that your Indian outboard motor is a 10HP outboard and not an 8HP as you have posted here. Production of the rare breed began approximately in February 1930 and was discontinued in August 1930. There were 600 early versions built with cast aluminum gas tanks with a nameplate on the back and two support brackets on the front. These are now known to be 1930 Indian Silver Arrow "Series 601" outboards. The later 900 motors were built with a lighter pressed aluminum gas tank with a decal across the back. The support brackets were eliminated and two standoffs were cast into the back of the muffler to protect the new gas tank. These are now known to be 1930 Indian Silver Arrow "Series 602" outboards. Feel free to contact me and I will forward a copy of an article that I wrote as I discovered Indian Motocycle Company's use of "series numbers" rather than "year models" to describe their products.
