"MY boat has two Cummins B ser
"MY boat has two Cummins B series 210 h.p. with a turbo, no after coolers. The engine water temps are 180 all the time so there is no problem there. However, at lower rpm's, 800 t0 1400, the exhaust hoses, pipes and water lift mufflers become very hot. Cummins has told me to change out the raw water pumps to a larger capacity wich I have done. This has made a difference at my normaal cruise speed and no longer hav steam out the back. Any suggestions as to what I can do?
