TI's
My boat came with BK Power 900Hp 12v71TI's that had 12v71TA 1080hp injectors . I have since detuned it back to Original Detroit Factory Spec....
Here are some GPH charts for the 12V71TI. at 1200 RPM you are burning 8gph and at 1900 you are at 30 gph. I have flow scans on my boat and that...
I am selling two Onan 15.0kw MDJF 3CR 2268 AD RTO´s from my ´86 Bertram plus extra parts. Both where running before removed and one had the...
rcrapps: That post of 10 psi was Turbo Boost, but I was taping into the wrong port . I am now seeing 20PSI at WOT of 2265RPM. Fuel Pressure was...
Capt J. Thats exactly what I am going to do. Once Im out of the Yard I will load her back up and will see where she is at. Frank and Jimmie's...

Another piece of information that I left off for this first sea-trial is that the Mechanics disconnected the Air/Fuel modulator on both Engines so...
No old injectors where traded in to remove core charge. Rebuild was caused by Startboard engine ingesting sea water on the right bank. Water...
I agree to cutting props some, but down to 29 x 29 might be too much. Im only dropping HP by 6.5% so I expect to get 26-27knots at 2300(WOT) and...
F&J does not lend out props.. I guess you have to be a Family member or something.
Thanks Capt. J. Good feedback. Boat is a 1986 54' Bertram with original 12v71TI's marinized by BK Power in Miami. 930hp using the 12v92TA 9A31...
Ship? I think you mean tranny. ZF BW 195's reduction is 1.54 or close to that. Engines were rebuilt in place. I agree the curve on the...
Before rebuild and injector reduction the old setup was maxing out at 2250 on a good day before engines lost the rest of their power. The...
2650 is the Max RPM no load.
My theory is that the Governor was restricted a little to prevent the large old injectors from dumping too much fuel and perhaps now with the...
