Today i changed the piston rings and bearing for the old cylinders.

----------------------------------

My spring project is to restore the a old boat engine to pristine condition. The idea is to look thru every moving part and make sure that there is no oil or diesel leakage.
The motor is a 3 cylinder yanmar 3hmf with a horsepower amout of 28.

If you are interested more about my project search the tag Yanmar from blip
