I found a 10 HP Honda BF100 long shaft for sale near me. It has a serial #160xxxx and will only fire if some gas is poured into the carb. Asking $400. The owner states that is has less than 50 hours on it and has a new water pump impeller installed. It looks like most parts are available for it including the carburetor assembly for about $140 if needed. Are these older Honda motors okay or should I stay away. I have been looking at mostly used 6 HP Johnson/Evinrude or Mercury motors because of parts availability and lower initial investment. My 8HP Mariner needs parts that are not available. Part of my concern for the Honda is that it is a previous generation four stroke therefore might need more maintenance (valve adjustment) and be less reliable than two strokes of the same vintage. I will repair myself if purchased as I am mechanically inclined. It weighs 77 lbs compared to 64 lbs for my Mariner.
