Hi,
Depends on which mount that you are having issues with. I bought this 98 Merc Mystique some months ago and YES, it banged into gear and felt like a broken engine mount. I found the front one and the rear one broken all to pieces. Got replacements temporily at U-Wrench-It and found that you can remove them both in 2 sections and replace them after supporting the engine and unbolting the center bolt, then the mount. I put the used ones in and WOW..what a difference in putting into gear. Like a new car! I am soon ordering the center inserts that are replaceable from RockAuto.com which have them listed for $20 each. There is another mount under the air cleaner box that some CEGers have found broken center bolts on also. Good Luck...Duane Koss/Blue Springs, MO
