Jabiru 3300 Power settings and fuel consumption

Postby MHaines » Tue Aug 23, 2016 3:09 pm

Greetings all;

I am new to this group and new as a Jabiru owner so please forgive any and all of my ignorance I may show.

I have a Zodiac 601 XLB with a Jabiru 3300 installed. I would like to know what the cruise power settings are. I believe the proper setting is 83% (100 hp) for cruise. Which, if I am correct, is achieved at 2,490 RPM at seal level. I would like to know the appropriate 83% power setting (or proper cruise power setting if not 83%) for higher altitudes like 5,000 and 8,000 feet.

I would also like to know what the normal fuel consumption is at various power settings. I know I have seen this information before, but I cannot seem to locate it now.

Any and all help will be greatly appreciated

Hello Mike,

Max continuous for your engine would be 3300 RPM (shsould deliver 120 HP).

I have cruised on a J400 equipped with the early Jabiru 3300 (big heads and solid lifters). It was comfortable at 2900-3100 RPM at 4-5 thousand all day and two up, it seemed to require around 22-24 lts per hour. The 83% should be based on the Max continuous RPM which is around 3300. Therefore, cruise RPM should be around 2750. I would add that the jabiru engine, according to various reports I have seen, produces a high level of harmonics around the 2300-2400 RPM therefore it is advisable to run it a little higher than the known problem RPMs.
