No need to re-rig to a lesser drive, Konrad's 540PRS is a direct bolt-on unit designed to replace the TRS. It's 1.7" shorter from input shaft to prop shaft. This increase in propshaft height typically results in gains of 3-5 mph when compared to the TRS. 7 qts gear lube capacity, rated to handle up to 800hp.

Bravo drives belong on a house boat... Listen to Biggus you can't go wrong

Thanks Steve -See you in Miami!

With your motors sitting 2 foot forward, 3 inches higher, 200 more weight, more hydrodynamic drag, and needing an extra 100 ponies. Yea I would say even if a TRS could somehow hold 150 more hp than a bravo it would need more than that to equal to performance.

No need to exaggerate. TRS applications are about 10" further forward compared to Bravo. X-dimention is about the same, TRS were installed deep. TRS is heavier by about 120 lbs. Trans are 1:1, other than a small pump and viscous drag, there's not much loss. BAM calculates a 72C at about 12-15 hp.

Yes, there's speed to be gained, Bravo to TRS but most gain is from the ingrease in propshaft height with the Bravo being about 2.5" shorter than a TRS.

Swapping from TRS to Bravo is a huge undertaking with the end result, a weaker drive.

Trs, transmission, whatever parts are way more than 120 lb heavier. TRS is 3 inches longer. Hydrodynamics have to be worth a bunch.

i liked your 540's so much i had my TRS's painted to match. Hopefully one of these years i can have the real deal

The trs is 2.5 iches longer like biggus said..But you do shed alot of weight I would say about 275/300 per side. The trans alone is about 125/150. I have done the conversion a bunch of times and every time a big difference in performance..two of them were mine. One was a 27 excalibur with the same motor and the x was 19.5 with the trs when i converted it to bravo I set it at 19 and i gained a best of 7 MPH. Boat ran a best of 80 with the trs and that was only once, then when a did a bravo 87 MPH and that was a bunch of times... My 10 meter I gained 6 mph and the boat handles way better. If you can do it yourself I would do it. A bravo boat will sell alot easier than a trs.. Just my 2 cents
