It is Time to Replace Our Engine Mounts

Cam at West Coast Marine Diesel noticed the port engine was vibrating left and right a bit  when were in Sidney. After further investigation, he recommended we replace our engine mounts. We replaced the prop shaft and cutlass bearings on the port side two years ago. We certainly don’t want engine vibration to damage any of that rather expensive work. We also have no idea how long the current mounts have been on the boat. For all we know they could be the original mounts. Replacing them seems like a reasonable thing to do. And, of course, it is another project for me.

I spent some time looking around the interwebs and for no quantifiable reason decided I would give Poly Flex engine mounts a try. That’s not entirely true. I could have gone with the same model that is on the boat now. I could also have pursued fancy (expensive) mounts from other manufacturers. I decided not to use the same mounts. That’s at least a thirty nine year old design. Of course that doesn’t mean it is bad in any way. While I am sure it would be fine, I wanted to try a newer design with newer materials to see if I could get the engine vibration down a bit. Maybe it will work, maybe it won’t.

Hugh Carroll at thermoboat.com was kind enough to help us out with the Poly Flex mounts. Thermoboat is the Canadian distributor for Poly Flex. It was handy that the boat was in Sidney and thermoboat.com is in Victoria. Hugh was kind enough to go visit the boat to be sure he ordered the right mounts for our boat. He was also kind enough to deliver the new mounts to the boat before we picked it up. Isn’t that a fancy looking engine mount?

This is going to be a big project. And I have only a vague idea of what I am doing. That’s not stopped me before, although there have been a few time that it probably should have. It sounds straightforward. Disconnect the shaft, jack up a corner, swap the mount, etc. The challenge will be aligning the engine with the shaft after the mounts have been swapped. How hard can that be? 🙂

I think I’ll attempt this project later this fall. We are bound for Canada shortly and I sure don’t want to do something I might regret before were go.
