One more point (been resisting do to not wanting to jinx myself) is that I don't follow any recommendations that I probably should. I don't use a stabilizer, I don't shut off the fuel valve and run it till it dies, I don't run ethanol free gas...hell I don't even winterize it. One thing I do though is run the boat year round, which I think solves a lot of problems. At least a couple times a month throughout winter. If I lived in the cold country I would definitely be more pro-active with preventive maintenance. Anyhow...it starts on first pull every time. I love my Nissan / Tohatsu outboard. Geez...I hope I didn't jinx myself.
Agree, if you use the motor on a regular basis and get good quality fuel and check your filters regularly, you probably won't have any problems. I never used to drain the carb on a number of motorcycles, but I rode all year although not too much in the summer.
As mentioned, the only problem I had was to forget draining the carb on my Honda 2 HP outboard which sat all winter, that one got me. I do use Berryman's fuel additive, which absorbs water, which I understand ethanol fuel absorbs from the air? Not sure if the additive is necessary, but I don't think it hurts anything?
