have been trying props without much success 23 pitch fury 60 mph 5700 rpm.24 fury 61 mph 5600 rpm. 24 pitch fury 4 blade 63 mph.5700 rpm. all gps speed ptp height 2 1/2 to 3 1/2. 2021 250 merc.4 stoke 280 hrs. any help would be greatly appreciated. hole shot is good with all props. mid range and top speed pretty weak.
Might want to try a Tempest, Fury's were not the best for me on my z9 of those years.
But your getting rather high slip numbers. Do you know how the boat ran with the 2 stroke?
ran a 27 bravo1 xs 70 to 72 2 1/2 below the pad strong mid range good top speed handled great just had a chance to upgrade to a 4 stroke
U sure your getting full throttle? Could the tach be off?
going to my merc.mech. this week to check hot foot setting ecu setting and trim setting hopefully they can figure it out.
Did this get resolved?
i took in in and this is what they found had to reset my older hotfoot also had to reset the trim range it was off by a good margin replaced the spark plugs believe they were original took it out and ran it and the results were71 gps speed at 6200 rpm analog tach off by a 100 rpms high that was with a 24 pitch fury 3 at 3ins below the pad pretty happy with the results my ech. also said i could lower the engine a little and prob.gain a little speed.would like to say thanks for the help also on a side note would a 25 pitch bravo 1 fs be a good choice for this setup i have had good luck with bravos in the past. thanks again
Bravo would be a very good option. I can't answer on pitch but think a 25p bravo might be not enuff. I think a 25p bravo is like a 23p Fury on RPMs. Someone who knows for sure can chime in.
This is a good thread for me. I have a 2013 Z9 with the same motor and am getting poor results. I’m going to the shop in the spring a I only ran the rig a few times when I got it. Thanks for posting this
Paul what prop u running? and RPMs
Currently I have. 23p4 blade fury 4 I think I seen like 5500 rpm
Yeah, U need some RPMs. Like u mentioned taking it too shop to inspect that your getting Full throttle.
I will report back in the spring when I get it set up right. This set up should do 70 pretty easy. I'd be more than fine with that.
