How did you decide which mounts to buy? How were the Barrus mounts that you decided were too expensive specified?
I always remember when my original mounts wore out, well one of them, I enquired at a chandlery and bought a new set. I spent several months trying to settle them in, and eventually found out that the original mounts were R&D mounts so I phoned them. I had to supply details of the boat length and the engine, gearbox and drive coupling and was quoted for a pair of front mounts and a pair of rear mounts. When I asked why I shouldn't fit 4 of the heavier ones, the response was that if I wanted to discount the advice of a manufacturer who had designed a product to do an important job, then that was my privilege. I bought what was specified, fitted them and immediately the vibration and noise stopped. They weren'y cheap, but you get what you pay for.
