23 sceptre performance

[McGillicuddy]

I hear you on the value of performance whether you can open it up or not. And frankly that hull probably takes a snotty day on Buzzards Bay as well as any thing

Pictures would be helpful but the thing you noted that struck me about the bracketed boat was the motor height. You mentioned it was mounted low on the bracket...

I think most bracket builders recommend 1" elevation per foot of setback. The SeaCraft hull seems to want a little more.

Assuming a 30" setback you'd be looking for the anti-cavitation plate to be 3-1/2" - 5" above the keel trimmed parallel to the keel. Also, do you know if the bracket was built for the Sceptre transom or a random add on.

If height and bracket angles are good, then a compression test is in order

My twins are set where the water is just above the water pickups on a plane cavitation plate is dry.

I have a 300hp Etec and a large hardtop.
I get about 2 mpg at a about 27mph.
WOT at about 5700 RPM is anywhere from mid 40s to low 50s mph depending on conditions and load.
This is with a 4 blade prop. I don't recall the pitch but can report back on that if anyone cares.

I care.

Thanks for the feedback.

How many gallons does the tank hold ?

FYI - Here's an article I saved from Boating Magazine from 1973 where they tested a couple of the 23'Tsunami/Sceptre's with a pair of I-6 Mercs and MerCruisers that will give y'all a feel for the boat's performance when new!

My tank holds 90 gallons. I just noticed that someone did actually want me to check out the pitch on my prop. I will try to remember to do so tomorrow. Sorry for the long delay. I know I owe someone the length of the setback on my platform too.

a 300 set up nice and high with a good prop without a hard top will damn near
scare you - trust me
I had a V8 Rude on one, not that you can afford to feed one now, but it would run - in the ICW you have go fasts reaching for the trim button

a 250 which you could find more options on would be great
