whats your Top End on 23s

[jobu]

I have a 23' Sceptre with a 200 Mariner 2.5 carbed...no bracket or hard top(pretty much factory weight) I don't think I have alot of pitch on the aluminum prop as it gets out of the hole very well.
My GPS says I am going all out 36-37 mph close to 6000 revs.
I am curious what other people are running and topping out at in any 23' configuration (sf,mf,cc...bracket or not. I am thinking of a bracket and an E-tec 250 or Suzuki 300fs but this motor is a great runner!
Please add any info...thanks, joe

Your boat looks awesome...I am thinking of the same color scheme with Awlgrip. What do you have on for props.
What would you estimate a 250 E-tec will doe on a Sceptre with a bracket?

[peterb]

I would guess that you could get somewhere between 46 and 48 mph with an ETC 250.

I am using Yamaha SWS props (21" pitch and 14 & 7/8 diameter). Also, I just moved the engines up 2 brackets.

I'm low 40's w/250 2s Yam., bracket, (probably mounted too low) w/17 Yam. ss prop., 1/2 tank, calm, best conditions, etc. I will have more HP at re-power, for what that's worth....

did you try spinning your props out prior to current setup?i first setup my sceptre to turn in, but would only run about 56 got alot of transom lift but would bury the bow.got 6 mph and made it maneuver real easy could not make it
go anywere in close quarters on one

when i first bought the boat, it had batteries (group 24) an oil tanks inside the console, and yamaha sws 19 pitch props turned to the outside, the 19 pitch 15 1/4 dia. sws manhandled the boat; if i trimmed out even slightly after getting on plane i had to use a lot of tab to keep the boat from porposing, this was also with no jackplates. the jackplates were bought primarily for the setback; 2 reasons: 1. engines would hit inside splashwell if trimmed and turned/more splashwell room 2. wanted the engines in cleaner water; thats a lot of power doodlebug; what props are you swinging? i plan on posting pictures for the website soon

cruse.
