I have a Westerbeke 4-107 which is a Perkins "marinized" by Westerbeke. I don't know if this applies to the 4-108, but I had an overheat problem last summer. It turned out to be the oil cooler heat exchanger which had clogged with old disintegrated zincs. This engine has 3 heat exchangers, the main fresh water cooling, a transmission fluid cooler, and the direct oil cooler. If any one of them restricts water flow the engine overheats. Normally I would notice this in the amount of water in the exhaust (my boat exhausts out the side, above the water) but it had been bad since I bought the boat and I thought it was normal (until it was fixed). I guess this is a tribute to the safety factor that was built into the heat disposal design.
