I want to know what prop works best on the Fastech 271 hull
running a 502 with 1:65 ratio 26 pitch B-1 puts me at 60.8 on gps turning 5000 rpm, would a 5 blade work better ?

what year, and are you sure it's a 1.65 and not a 1.50 , I do'nt think thay did a 1.65 with that motor the revlimiter with a502ci efi is 5040 , your speed is it off the speedo or gps .

I've tried a few different props. I tried a 5 blade which helped a lot out of the hole but gave too much stern lift and I lost top end. When all was said and done, I sold them all and went back to the 4 blade Bravo. It seemed to be the best all around prop for my 99 271 hull. I also have the 1.65 LH rotation drive.

I have a non stepped hull and 28p 4blade bravo. doesn't come out of the hole for S*** but, I dont mind. I got a little more power than stock and seen 79mph not trimmed. Still getting used to the boat. Maybe nexted time out i'll trim it to the moon and see of we can get to the low 80's

I have been testing props with Bblades this summer and this is what i found out. My boat is a 2000 271 fastech. Stock 502 mpi with 1.65 ratio Bravo outdrive. All speeds are on my GPS speedo..... 24 pitch Bravo 1 4 blade [email protected] Pitch Bravo 1 4blade [email protected] pitch Maximus 5 blade 59GPS@4900.... I have now ordered a slightly modified 26 pitch Bravo 1 which will hopefully get me to the 5100 RPM and a couple more MPH. I will let you know when we are completly done and what turns out. The 5 blade maximus DID NOT help the boat come on plane any faster and the prop still blew out just like a 4 blade. Jeff Wurl
