35 Cigarette Mistress 600hp propping Question..
 

Just did a repower to 547CI 600HP engines, TRS boat.. 85 Cigarette Mistress...598HP@5200 rpm, TQ was 660@4200 and at 5200 the TQ is still 606ft lbs drives spinning out, don't wanna spin in, handles better out...

So far I have one engine 200 rpm off, fixing that now, but wanna see what thoughts are as of props...

boat with old engines went a best ever of 64.8 @4900 with 3 blade quicksilver repitched to 24... approx. 450-470hp...

Now same props last weekend got easy unturned gps of 69.4 port at 5300, stbd at 5500...

I am pretty sure I will end up with a 25P Mirage plus but what else should I look at? A buddy has a set of labbed 24 Bravo 4 blades, would they be worth trying? I am not too comfy with 4 blades and TRS with 600 hp, but maybe???

I am going to do more tuning as I think there is a 70-72 with the 24P but I am starting to pass the peak HP range with them, thinking a 25Mirage plus puts me around 52-5300...

Is your buddy nightlife1970?? He has labbed 24p b1s that sound like they are labbed and cupped to around 25p.. they are on swap shop now!

He is supposed to try to get some cruise #s this weekend so we can estimate pitch. If 25p, they would be good for you, if closer to 24.. better for me and I have 25m+s now that we might be able to work a deal.. just a thought...

No Frickstyle is local to me and has some....

Either way, labbed 24s pitched up a bit could work for you if your thinking you'll end up at 25m+ s..

Good luck..

Let us know if you would like to try some Mirage + 25's through our test program.

What seems to be best? 3 or 4 blades on a Mistress? Are 4 blades really any harder on the drives if slip factor is same? Or close?

Id also consider trying a set of 25P Revolution 4 props. Work awesome on heavy TRS boats.

+1 usually 1 mph faster then a migage +..the trick to keep a try alive on your boat is to wind up the engines and make sure you slip numbers are up and no huge wave hoppin...once thewy get a good bite pop goes the drive..one og my friends use to have a 38 fountain with trs drives and 600 sc's..he has 27 mirage + on the boat went to a set of 26p hydro's and popped both drives the following weekend..got rid of the hydros and stuck with the mirage +

I get the extra slip on a 3 blade helps drives, but at what MPH cost?

Tim if the trs drives r beefer then my bravo 1 x drives I think u will be fine with 4 blades I am turning 28 4 blades on mine. Also I know u there is no way u r going to go with out big water and big air. That will never last with u lol
