What to do if my Yamaha YP20G does not draw up water?
If your Yamaha Water Pump isn't drawing water, start by checking the priming and drain plugs, as well as the hose joints and bands; if loosened, tighten them. Also inspect the O-rings and gaskets for damage; if damaged, replace them. For a damaged mechanical seal, consult a dealer.
Why won't my Yamaha YP20G engine start?
The Yamaha Water Pump engine might not start due to several reasons. It could be that no fuel is being supplied to the combustion chamber, or there's no fuel in the tank. Other potential causes include a clogged fuel line or carburetor, foreign matter in the fuel cock, or a low oil level. You may need to supply fuel, clean the fuel line or fuel cock, clean the carburetor, or add engine oil. Also check the spark plug; if it's dirty with carbon or wet, remove the carbon or wipe it dry. In some cases, loose cylinder head nuts or a damaged gasket may be the culprit; tighten the nuts properly or replace the gasket. For faulty ignition systems or worn-out pistons and cylinders, it is best to consult a dealer.
