I was actually replying to a post on a VST and realized I should share this with anyone who has a 4 stroke Yamaha. I know it’s summer and you won’t be winterizing the boat anytime soon, but i’ll share it non the less.
If you have a Yamaha 4 stroke, you have whats called a “Vapor separator tank” on it. It’s like a small fuel tank on the motor that houses your high pressure fuel pump. The problem is these tanks get residue and old fuel buildup in the bottom when you let them sit for more than a few weeks at a time. This makes the motor run like $h!+.
The solution…
It’s far better to keep fresh fuel moving through the VST then to drain it. If you absolutely have to leave the boat sitting for a long time, drain the VST and connect a remote tank and primer bulb filled with a gallon of non-ethenol gas + 1 oz sta -bil and 1 oz yamaha ringfree. Prime the system with the storage gas and then cycle the key switch a few times (to kick on the fuel pump)until fuel starts coming out of the drain again. close the drain and cycle the key a couple more times. PRESTO! You have a pickled VST.
I started doing this when yamaha 4 strokes first came out and it works like a dream. You won’t find that in any manual.
Maybe I should patent that? I’ll call it Andy’s Yamapickle.
Happy fishing.
If anyone is going out Sunday i’d gladly go with.

There is not much I don’t know about boats, but somehow I still see something new every day.
