My son asked me if my motor movers when I give it gas,he said that his really moves up and down, Yamaha 700 2010.

We check it with a flashlight and discover the front right motor mount is bad, get it stood up pull bottom skid plate off for the first time since we put it on in 2010, three motor mounts are bad.

Most likely will change all four, Any advice, does or don’ts appreciated.
