Query: Excellent for my Yamaha Jet Ski !

Brought this to change my Yamaha VX110 jet ski's engine oil. The product was well packed with clear instructions and was very easy to use. I think its helpful that the engine was warm and that the container was placed inline or just below the level of the engine to improve the syphoning effect. A few pumps of the handle and the oil started to flow into the container and took only took me around 5 mins to extract nearly 4 litres of oil.Looks to be well made and durable for the job/s ahead. The end hose is around 5mm in diameter so should fit into most dipsticks although on the Yamaha jet-ski it went directly into the dipsticks oil tamk.Be careful and there's no need to make any mess except perhaps a few drops of oil.Real easy and saved me a sure $70+ for getting someone else to do the same job - so it's paid for itself already !!Hope this helps and don't be afraid to try an oil change yourself good people !Chris
