Single Handed Marine Diesel Engine Removal

Removing the Yanmar Marine Diesel Engine from our Mumm 36 could have been a tricky job due to the limited space above the engine cover. The removal of the engine was a key step in rebuild which was made easy with the constructions of a crane which allowed our chief engineer and mechanic to do it single handed. The removal of the engine was key job that needed to be completed so we could see what other work was required on our Yanmar Engine and the connected saildrive. We had experience issues with the engine on the trip up the Irish Sea after her purchase and wanted to ensure that we would not have any problems once we completed the rebuild. We put the crane together reusing some steel frames, old blocks and wheels with it costing less the £20 for the nuts bolts and washers to put it all together. It would usually take 3 or 4 bodies to remove a Yanmar Engine of this size which weighs approximately 120kg. Due to the limited space above the engine cover on a Mumm 36 and no access to lift it externally building a customer crane was the only option. Using the crane to remove the engine had the added benefit of reducing the risk of further damage which may have occurred if we tried to lift the engine manually. As with many steps in the rebuild it was amazing to see what our chief engineer could achieve single handedly by planning out the job.
