New installation looks damn nice Monaco! :whistle:

What rpm range are you looking for? My friend spins a 3 blade 25 on the same boat with a 500hp, right at 5000 rpm. My guess would be to start there or a 24 4 blade bravo prop.

Thanks :-)

I am more of less happy, but we did everything in a kind of hurry, to get something out of the summer.

I will tidy up some of the wiring.
I rember your instalation of the 496 HO in your 242 LS
that was something else, almost perfect

Best regards

Thanks for the reply

I was thinking the rpm range should be 5000 - 5200 so
mirage 25 plus could be a start

Do you know what kind of speed does your friend do?

66-68 mph 3blade mirage 25 pitch

Did your 242 LS 496 HO make 56 knots aprox 65 mph gps ??

Thats not bad, must have been å god combination :-)

My engine was a high revving 439 with around 525 hp. My best prop was a Mirage Plus 21 pitch at 5900 rpms. I was typically at 68 MPH.

On a good day I saw 64-65 mph with the 496HO and superlabbed 28p with 1.65 drive ratio.
I saw 62-63 everyday.
But the 4 blade definitely gives some advantages in acceleration and hole shot!

I think you should start with a Bravo I 24p 4-blade. If that is to small go for a labbed 26p..
Testing props is fun!

Happy New Year all

Any one have exhaust system with tall pipes in their Formula 242 SS ?
