23p prop on a 242
 

hi all! im new to this boat and just wondering if anyone is running a 23p prop and how they like it cruise, out of the hole top speeds etc. The boat is an 89 242ls with a 454mag and bravo 1. I am currently running at 21p mirage and seeing 5k rpms and 56/57mph gps, I would like to get the rpm down a little and maybe see some better numbers up top.

i run a 23 mirage non plus on my 242 . i see about 66 mph (gps) @5200 with 3-4 people and and a half tank of fuel but thats with a 502 with about 475 hp

thanks. anyone else.....

What 21P mirage are you running? Plus or non Plus?

Non plus

I think you would be right where you need to be with a 21 mirage plus then.
Our 242 ran much better with the added cup of the stock mirage plus props. Carries the bow and rides much better with the added cup.


There is a cheap one to try listed here:

On my 242 I run a bravo 1 four blade 22p best I have seen is 56gps, my four blade is labbed a little bit.

what kind of hour blade? im supposed to try out a hydromotive 23p 4 blade this week.

I am running the Mirage 21plus that came on my boat. Can only get 45 Miles per hour at around 5200 ( 454 /400hp). Salt water. Not sure whats wrong. Previous owner got 60 mph on lake.

Def something wrong there. Sounds like you're getting too much rpm and way too little speed. Are you trimming it out etc. Is that speed GPS or the speedo?

Don't waste your time with the Hydromotive quad iv in any pitch. Mine came with one. 5 minutes after leaving the dock i had to go back to put the 23p mirage plus back on. It spun right up but did't lift the bow at all. Topped out around 30-40 mph. I get 63 mph on the gps with the 23p mirage plus. Power is a stock carbed 502.

my 89 242ls run a best of 65.5 on gps with a 502 cid with mild cam. EMI thunder manifolds. 23 mirage plus

I think you'll find the 21p mirage + will work the best. That seems to be the consensus for a stock 242. I have a 233 with 454 mag / bravo 1 and run the 21p + @ 56/57 and 4800-5000 rpm. I have never tried the non + mirage, so I'm not much help there.

My bad, had GPS on Knots . Today I was hit in a high of 59 mph at 5100 rpm.mostly wanted to only get to about 57 ish. Mirage 21plus. 454 with 400 hp.

I am running a 23P thunderbolt at 4800 on my 88 242LS with a stock 454 mag.
