Repairing a 2-Stroke Float Valve

The float valve is an essential component of any outboard engine because it controls the level of fuel present in a carburetor’s float bowl. If the levels are incorrect, the engine may flood out or starve for fuel. Repairing and adjusting a  is fairly simple.

Start by turning the carburetor float bowl upside down, so the float hangs free. Using a six-inch machinist’s ruler, check to see if the float is correctly set. If not, bend the small metal tab between the hinge and body of the float, so that is lies at the correct level. Don’t forget to check the levels of Yamaha oil when you’re done tinkering with the float bowl!

Pre-Thanksgiving Activities

I hope all you readers had a great Thanksgiving! It’s a tradition in many families to play football before the big meal. It’s a time of family bonding, but more importantly (according to my wife) it keeps the kids and men-folk out of the kitchen while the women finish preparing the meal.

Since we’re a boating family, we usually forgo football and head for the water. This year we took out two outboard motors. The teenagers earned the right to drive the boats by demonstrating to us “old timers” that they knew how to prep the boat by checking the Yamaha 2S oil levels and whatnot.

Used Outboard Motors: Good Idea?

When I shop for cars, I prefer to purchase slightly used or “pre-owned” vehicles. A new car loses its value as soon as you drive it off the lot. In my mind, there are only two reasons to purchase new: 1) if you are trying to build credit or 2) there are no quality used vehicles to be found. A friend of mine recently queried me as to whether I would buy a used outboard motor.

This one made me pause for a bit. Truth be told, I have always bought my outboard motors brand new. After considering his question, I concluded that yes, if the motor were in excellent condition, I would not be opposed to purchasing a used outboard. Of course, I would be sure to inspect the motor carefully, clean it, and fill it up with Yamaha outboard oil to ensure a long lifespan.

Checking Yamaha Outboard Oil Levels

All owners of Yamaha outboards should learn how to check oil. Depending on the tachometer your engine uses, the oil level indicator could be digital or analog. Look to see if all three blocks (digital) or all three lights (analog) are glowing green. This indicates that there is plenty of oil in the main and reserve tanks.

If you see a yellow light, then you need to add more Yamaha outboard oil. On yellow, your engine oil tank may be full, but chances are your reserve is empty. You don’t ever want your tachometer to flash red; that indicates a fill-up is needed immediately. To ward off accidents, make sure to bring extra oil on long excursions.
