I have Yanmar 6lp's on my boat and have gone thru two sets of dampers now. First one failed at approx. 700 hours, At 1500 hours the dampers failed again. I have Vulkan Torqflex and it appears they are making noise again with only 200 hours on them this time. I think I'm easy on the throttles so it really bothers me that I'm having such a problem. Has anyone else using Vulkan Torqflex having these problems? If so, where you able to find a remedy?
