There are two 60 p.s.i. injectors that are regulated at 40 p.s.i. The injectors regulate fuel based on the load put on the motor. The g.p.h. depends on the asking mode of the motor. The more load will equal more fuel consumption. As far as g.p.h., again, it depends how the boat is used. Hope this helps. Brian Raymond.

Thanks Brian, I however contacted indmar since i wrote that post to ask them. i was talking to james stewart and he emailed me they use 100 lb injectors. This seems
more appropriate when calculating injector size using h.p., duty cycle ,and b.s.f.c..
Any thoughts on this Brian.
Thanks, your info you supply to us on this bulletin board is outstanding.
