Ben at Gartside Marine Engines did an inspection on Alera last summer when I had an overheating issue. By the time a sailed and then was towed into Van Isle Marina in Sidney BC, the water flow recovered on its own. But he was very thorough, extremely knowledgeable and had an ear for diesels. So, I decided to take a day or two out of our cruise north this year to have him do the mounts and my semi annual service.
He swears by Poly Flex mounts out of Australia. IMO, Aussie sailing stuff is usually topnotch. Cheaper than the Yanmar ones too.. so, that’s what I’ll be getting.
