New boat to me. Just noticed on start up, very black soot then an extreme amount of raw fuel in exhaust, stbd motor. It keeps spewing raw fuel while running. Motor starts and runs fine, nothing in oil, anti-freeze normal. Any suggestions? Cool fuel unit??
does anyone know if the gen iii cool fuel unit internally failed with raw water, would that cause this amount of fuel in the exhaust?
