???Please report your experience with the Prince propeller on a Zodiac 601XLB with the Jabiru 3300 Engine. It would be nice to hear your Static, climb and cruise numbers. Knowing how the CHT & EGT temps are affected would be helpful. Fuel burn and other engine info please.???
I been reading about the P-tip carbon fiber coning prop by Prince. 58x48 are the dimension that they recommend for my A/C. My Current prop split on the tip and I am about to buy a new prop.
Recently, We replaced the Bing Carby w/ a Rotec's 40 TBI to my Jabiru 3300. Here the results: (After 25 hours running) Still using same throttle system and air box system.
1. Now can reach 2850 rpm in static run-up.
2. Shorter lift off distance.
3. Fuel burn @ cruise 5gph.
4. EGTs closer. CHTs cooler.
5. Able to control mixture.
6. Very easy Starts.
7. Only use electric fuel pump for first start of day w/ primer once.
(690 Hours total time.)

New pistons and new hallow rod & valve system assem. Need control of mixture so we are going with Rotec TBI, dropping Bing. Will…Continue
