I am new to the jet skiing, But I just bought a 2003 Honda R-12x. I keep reading on here about all of these lubes and oils and where you should do it everytime you ride. Could someone specify what exactly I'm lubing or spraying wd40 on? Also I got some salt water in the hull after riding in some very rough ocean, is there a way to get all the salt off the motor that has formed on the motor.
