I expect any quality brand of new engine mounts will noticeably reduce the vibration and its associated harmonics. Before I replaced Calypso’s engine mounts (2 looked original, 2 only 20 years old), at idle the vibration and harmonics shook the boat enough that the spinnaker pole (in its deck mounts) would deflect in the middle and strike the deck making a pinging sound. After the replacement and re-alignment the vibration was significantly reduced but not eliminated. I still stuff a few pieces of cardboard or other dampening material in several spots (the usual suspects) when under power for more than a half hour or so. > That's part of the reason it really makes sense to do now. Bingo. Based on your pictures, are you able to slide a piece of angle iron under the rear mounts to create a lifting point? Also, does your boat have a V drive or did I interpret the pics incorrectly? I started a response to your question regarding my comments on lag bolts and other engine mount issues. I spent the last two days on Calypso laminating up a large repair area (7 ½ sq. feet, close to a gallon of resin) so I am backed up a bit at me day job. I should get it out later today.

Here are some pics of my existing mounts: https://drive.google.com/folderview?id=0BxfHpwssU_6NfnpXZjYta205U0pmeW1Ba0Fla2U3YmNBX1ByU1c4TURtb0ZaVDk2VVFQQ28&usp=sharing The Vetus mounts don't look very good. I have heard people like the captive attributes of the PYIs, and the oil/fuel shielding. The oil/fuel shielding doesn't seem like a big deal to me because the Yanmar OEMs are shielded from the top as well, and it doesn't appear the engine mounts have ever had oil or fuel spraying in from the side on them anyway. The captive aspect is nice, but considering the Yanmar ones I have now are probably original, they lasted 31 years and are still in good enough shape that I wouldn't worry about the engine flying off. The main selling point of the Yanmar one is I read a couple forum posts where people said the Yanmar ones had noticeably better vibration dampening - meaning less vibrating of lazarette lids and the cockpit floor. I don't need to do the realignment because the mechanic I'm paying to do the transmission reinstall will do that. That's part of the reason it really makes sense to do now.
