This report describes investigation of tow-boat traulers in the east china sea with medium-speed diesel engines burning blended fuel of Bunker C and marine diesel oil to save the fuel cost.<BR>Performance and maintenance of engines were investigated and compared economical efficiency of blended fuel with marine diesel oil on fishing boat engine.<BR>Running the engines in its standard marine diesel oil form except for fuel heater and Stellite-face exhaust valves on blended fuel proved to increase exhaust temperature and specific fuel consumption. Maintenance interval of valve, injector and turbo-charger reduce about a half period in comparison with burning marine diesel oil.<BR>However satisfactory results was obtained on newly-built fishing boat with new engine which had sufficiently considered the counterplan for low quality fuel.
