As promised, here is an update on the engine replacement we did. You may recall an earlier post on this job where we re powered this boat with a 33hp M4 Vetus diesel engine. We now have the engine running and have performed sea-trials to test the shaft alignment and engine rpm under load. Part of the work included a new 50mm wet exhaust to replace the old 40mm system. To improve the system we moved the exhaust through-hull fitting close to the stern rather than where it was, which was adjacent to the engine on the side of the boat. This was an issue when sailing if the exhaust was upwind and would blow into the cockpit. To neaten up the system where it ran across the bulkhead we used a high-rise vented elbow made from poly pipe. We also replaced the fuel filter with the recommended Vetus brand along with new fuel lines. Another challenge was to re mount the fridge compressor to run off the engine. There is a specific bracket for mounting items such as this which took care of the top but we designed a custom bracket to attach to the front engine mount bolt at the bottom which was slotted for tensioning. This boat also had the hot water running off the manifold which required a kit from Vetus to be fitted. Following a 2 hour trip across the bay, all warranty data was collected and a careful eye was kept on how the engine was running. We were very pleased that everything ran perfectly and the prop shaft seems to spin without the previous vibration.
