Author Topic:   Winter Storage of Yamaha 130

I have a 1999 Yamaha 130BETO carburtor two-stroke-power-cycle outboard engine with 217 hours of run time. For maintenance I run the motor on flusher muffs for 15-minutes every weekend through winter and summer when it's not being run on a freshwater lake or river. My annual running time is about 300-hours in summer. The boat and motor are stored under cover in a garage. I have had minor [malfunctions] of the fuel pump diaphragm and electrical [malfunctions] on the boat itself, but [the 1999 Yamaha 130BETO outboard engine] runs like a dream: starts first time, every time and looks new. Compression test reveals it to be at factory specification, and I use Fuchs TCW3 outboard oil. Is it a better plan to [maintain the 1999 Yamaha outboard engine] this way, or to winterize the motor for non-use in winter? Any comments would be welcome. Hi guys and happy new year to all! Thanks.

The concept of "winterizing" an outboard engine is to prepare it for long periods of non-use. You seem to be continuing to use the outboard engine during the off-season by starting and running it for 15-minutes.
If you prepare the engine for non-use by following the winterization procedure, you won't have to go to the bother of running it for 15-minutes every weekend. For me, that would be a significant advantage of winterizing the outboard engine.

I have the 1991 version of that engine. In fact, I have 2.
Come fall, I pull the fuel lines off while it is running, and when it begins to sputter, I choke it by spraying fogging oil into the carb intakes. Then maybe 3 minutes per engine to pull each plug and put a shot of fogging oil into each cylinder.
Total time to winterize 5 minutes. Not sure why you would bother to run it every weekend unless you just like playing with your boat in the driveway...
My engines have never failed to start come spring (usually on the first turn of the key).
