225 SHO RPM's still low on 919-25 T1

[Bonanza]

Posted this elsewhere, just trying to troubleshoot...
2017 225 SHO on a Phoenix 919, 50 hours on engine. 10" manual JP, PTP 2 5/16". Light load, me solo (150 lb), no anchors. Engine data cable with digital tach. VMax SHO 25 T1 prop. Could only get 5750 max rpm's in cool weather so I sent prop off to Mark Croxton for evaluation, B&B. Prop returned and I'm still low at 5850 max. How do I make sure my Hot foot throttle is maxing out? Could be driver but I feel I have mastered the chine walk.

what is your speed at 5850?
how much trim?
how is the hole shot
Did Mark know you were looking for more RPMs?
just trying to get a feel for what you got going on, sounds like your setup is good but you should be able to hit 6k with the T1-25

back the stop screw out on the hot foot and have someone press it down and watch the throttle on the engine and see it you can move it anymore by hand, it has its own stop and the screw in the hot foot should match up, dont leave it screwed out too far , dont want it putting extra force on the cable

50 deg F speed -73
trim ?, no gauge...any higher and it gets too squirly with no increased RPM or speed
hole shot great (CB Bailey plate)
Told Mark I wanted 6000 RPM

[DREWTICK]

I dont see 6000 until Im at almost full trim, my trim is connected to the lowrance and goes from 0 to 110 and my best speed are at 95, thats 7/8 on the factory gauge but that is also when it gets loose but im just used to it.

Id like to have a CB plate, cant bring my self to drill holes in the SHO while under warranty.

raise plate a bit. I know that sounds crazy but I run my boat runs best with JP all the way up on my 920 250 sho. both hull and motor loves to run high. I'd raise to 2" even and try. My jackplate setting has me at right around 2" even

but also best speed isn't always at highest rpm. when I'm running perfectly on pad at WOT I can play with trim and fluctuate 150rpm without changing speed. I'll loose .2-.3mph and be able to keep increasing rpm while speed remains the same. then bump trim down a tap at a time until I pick the speed back up.

I agree , when the water is flat i run at 2" also

How can you connect it to the SHO motor??? I was told that it can't be done with an SHO to a depth finder. Yes I now have the 'Yamaha Cable', but it's been too cold to install it.

And what is a 'CB plate'? Oh ya, one of those planing plates attached to the anti-cavatation plate. Yes? I remember you stating that before.

and maybe even a little less sometimes, but my better speeds are with a little chop.

Pull your cowel off the motor pull front cover off the motor there is a mark on the throttle body push hot to the floor and the mark should line up with mark on cable bracket
