got kenny keepers they probably double your mount life in my case two months if luckey i normally only break one at a time i thought i remembered LPW selling a mount called monkey grip but i cant remember any info?
Monkey grips are suppose to be stronger and last longer than OEM. Wamiltons also has their engine mount which I have heard is the same as the Monkey grips but just sold with the Wamilton name (I could be wrong on this, just a rumor).
Parkeryamaha.com sells the monkey grips and they are having a sale right now.
Also, if you are only replacing one mount at a time, that is a cause for breaking the others prematurely. When you replace only one, the new one is strong, and the remaining three are the new weak points.
if you need any thing shipped from the states Chris, let me know.
