Default Formla 242 ss prop question

Considering a 25 Mirage or 25 Mirage Plus, what are the handling and performance diffs? How would each help/hinder the boats characteristics? 1987 242SS Formula.
Thank you

We did back to back testing with a 25 mirage vs a 25 mirage + on a 242ls. The plus was better and faster. The non plus couldn't lift the bow enough. That being said he was 2 mph slower with the 25+ over a 23+ running 68 and 70 respectively. With 500 horsepower it liked the 23.

Mr Main, good info. What RPM was the boat running? My HP should be at the 500 level camed for about 5400-5600 rpm. When you say not enough bow lift what would be the symptoms? Any idea on the slip #'s? Sorry for all the questions. I now have a 21 Mirage/23 Mirage/27 Mirage + . I am looking to trade the 27 as it is most likely too much and trying to get close, would also consider trading the 21 as it better be too small.. Any help or experience is welcome.
Mark, I hear you with the trial and error, trying to get things ready for later this summer splash. Talk with you soon.
Thanks again.

I don't have the exact numbers but I want to say 5400 with 23+, 4900 with 25+ and 5000 with the 25. The 25s were a little too much but we're doable. The extra cup of the + lifted the bow better getting the hull out.

Turning a 25+ to 5600 would be close to 80 or so you probably need a 23+. His boat did 58 with a 365mag and 21+.

I am aiming to prop limit the revs to about 5200. That is a sweet video I have seen it several times.
My other question is the SS vs LS from what I have read the SS has more weight forward and what effect that may have.

Yeah the ss is a bit slower due to more bow weight. The more cup of a mirage + should help with that.

Bravo 1 four blade 22p is perfect for your set up. Great holeshot, grip through turns,boat tracks straight,I am selling my Mirage plus 23p because the four blade is so much better. I turn 5200 wide open with my 490hp 502. i dont have Gps but im running right with a 70 mph jet ski that my buddy has. not sure how accurate those speedos are either. We ski, tube,and wakeboard behind the boat now.
