An old thread, but what the heck...
Over the course of 8 seasons, our current 3 cylinder 27hp diesel has consistently burned about 1/3 gph during normal sailboat operations. We push it hard (2700-3000 rpm whenever we're motoring, except when docking and during warm-up/cool down).
Our previous 2 cylinder 18hp diesel burned about 1/4 gph during normal sailboat operations.
Hello, new to your forum...
By "normal sailing operations", did you mean your motor is running to assist your sails, or running alone, under full load???
Is your diesel motor really that efficient?
