In this video, we’re evaluating the fuel system on our Yamaha F225. Like the rest of the engine, this part of the outboard is a mixed bag of components that can be reused and those that must be replaced. John will show you how to test the fuel pump on your Yamaha outboard, and in our case there were some fairly obvious (and noisy) results. Then we’ll work on replacing the float needle on our F225.
After John shows you how to install the VST tank on the Yamaha 225, he’ll show you how to inspect the intakes and throttle bodies. He’ll also show you how to clean the fuel injectors on an outboard with a kit from Motion Pro (see the link above). Once that’s done, we’ll replace some of the seals to get the throttle bodies put back together again.
With everything put together, we’ll install the intakes on our Yamaha 225, and wrap things up by making some electrical and fuel line connections and attaching our throttle linkage.
