Winterizing your outboards to keep things runningPublished 10:36am Friday, December 7, 2012
Being winterized is something my boat has never experienced.
Its owner loves to fish too much in the winter. But most folks do let their boat rest in the winter months. And a little precaution can be well worth your efforts.
I asked Charlie Bramlett, a local boat repair man with many years of experience for some tips on what to do to keep your outboard safe in the cold of winter.
The thing he probably stressed the most was putting ethanol Stabil in your gas tanks. Put in the recommended amount according to the label, then run your motor a few minutes to be sure any gas not Stabil treated is out of your fuel lines and carburetors. Never run your engine out of water unless you have a motor flusher and a turned on water hose properly attached to your water intake. Your water pump can burn out very quickly without water.
The next step is one I had not heard of until now. He sprays fogging oil into the carbs or intake while the engine is running until the engine “chokes down.” This coats and protects the cylinders and carburetors from corrosion. You may or may not need a new set of spark plugs when you take your boat out of storage after using fogging oil, but it’s a step Bramlett recommends.
Check your lower unit oil to see if it has any signs of water. The oil will look milky white if it has water. If so, drain and replace the lower unit oil to prevent damage from freezing. It’s a good idea to change it anyway and now is as good a time as any.
