Thanks! I now realized I made an error in my original post. I have the PCM 40A transmission (1.23:1). Everything else is correct. Current prop is a 14x14 RH 3 blade ni-bral

Ah, that makes sense, most of these boats (Correct Craft too) switched to the 1.23 in 1989.
I can't recall if it's been emphasized here, but you should definitely know that a new CNC prop will be smaller in diameter and possibly pitch, too. This is largely because the overall surface area is so much greater within the circumference of the prop. Does that make sense? I went from a 14x16 to a 12.5x14.25 (however, the prop had been rebuilt and material removed so the actual outside diameter measurement was more like 13". I took a picture comparing an old prop to a new one side-by-side, I'll post it here if I can find it.
Resurrecting the old thread again.
1993 TS6M Comp
285 HP HO BOSS, GT head version with carb

Current prop is
13x13 original but is giving me poor hole shot and severe vibration compared to my friends TS6 Comp Classic.
Just ordered an ACME 541 13x12 0.08 cup
Used for Skiing, Slalom, Trick, Jump...very occasional wakeboarding....ABSOLUTELY NO BALLAST , 2 fat knackers in the boat is enough
Will post comparison when completed.

Right just fitted the new prop.
Old spec was
13 x 15 OJ prop
WOT 3800 RPM

Hole shot was poor.
Serious vibration on accel and cruise.
New spec
ACME 541 13 x 12 0.08 cup on a 1" shaft (good deal and great service from WakeMakers)...delivery to the UK within a week of order.
WOT 4300 RPM
V Max 44 mph via GPS with 2 passengers on board.
Hole shot ... OMG...takes off like a scalded cat with a rocket up its butt :O. I will time the 0 to vmax time later this week
Absolutely no vibration at all.
Wake seems very similar to before, no change in rooster position and no adjustment to wake plate.
Gotta love this prop

Old prop was the original OJ. Slight vibration. I though it performed well but had no point of reference. We bought the boat this spring. My first experience with boats.
Had read many posts praising Acme props and people saying they with they had bought one sooner. Decided why wait?
New Prop.
ACME 543 from Nettle.
Quick shipping, good service and a free t-shirt.
We are skiers, no ballast. Decided on the 543 due to our elevation. Lakes we frequent are between 3000' and 5000'.
As stated above by UKandH:
Hole shot ... OMG...takes off like a scalded cat with a rocket up its butt
Absolutely no vibration at all.
I agree with this 100%. The change in acceleration is very noticeable. Both hole shot and when already cruising. Plus it is super smooth.

Yes, gnarly I still have this set up. For my tranny (same as yours) and what we do with the boat it is great. really good hole shot even with 450 lb sack and 4 or five people. We ski and wake board with it and its been great. Just came home from the Southern Supra reunion; what a blast!
