"1988's with 1700 original
"1988's with 1700 original hrs and 50 hrs since rebuilds with cylinder kits, heads, blowers, injectors, fuel pumps and all new hoses. Ran fine this spring, crusing at 2000 RPM and maxing out at just over 2300, until one day I could not get starboard engine to go over 1900 RPM. My mechanic found one bad injector and I was back in business, maxing over 2300. Then last week returning from a three hour trip out I smelled diesel fumes on my return and turned around to see black smoke bellowing out my exhaust, again could not get above 1950 RPM. Temp. stayed at 180 with good oil pressure. When brought down to idle black smoke totally disappeared. My guy changed to more injectors with same results, with engine under load black smoke rolls out worse with every increase in RPM. Help!!!!"
