mercruiser longblock

[Carl]

The block was rebuilt in the summer of 2021.After 3 hours of running the front and rear main oil seals are leaking and also the headgaskets.The engine runs smooth and has excellent oil pressure and doesn't over heat. The block was rebored and the heads skimmed,new pistons,camroller lifters,cam bearings.valves,new sump and oil pump.I have now purchased a new long block,and this one will be out of my boat in the next month and on a pallet.I do not know what the engineer did in the rebuild process but obviously something is not right so will need stripping again and investigating. The only reason i decided to have the engine rebuilt initially was to freshen it up after a one cylinder was slightly down on compression. engine number ow621267 £1500 07801519700 facebook market place for pics
