I have a Catalina 400 with a Yanmar 4JH4E engine which supposedly produced a max 54hp at 3000 rpm. Actual fuel consumption will depend on hull, transmission, prop, auxiliary equipment, wind, and sea state.
I've not used mine enough yet to get a good feel for fuel consumption. However, Catalina lists fuel consumption to be 1.25 gph at 2800 rpm. Looking at the fuel consumption graph from Yanmar, it appears that fuel consumption at cruising rpms of 2400 to 2500 would be closer to about .8 gph.
As always, YMMV.
