I have an 05 Honda R12X. I topped of the gas tank before winterizing it. When I went to run it this year, there was a decent amount of gas missing and the oil smells like gas. Anyone know what might be causing gas to get into the oil? The waverunner is still under warranty but the service department is trying to blame it on me. The waverunner also started making a grinding noise because I ran it without realizing there was gas in the oil.
