Re: Flow-Torq II + 502/415 = ?
 

Well as predicted by others 5 MPH slower with the Mirage Plus 29P than with the 25P. Guess I found the limit that the 502/415 can swing. Back to the drawing board. :rolleyes:
Anyone want to buy a Mirage Plus 29P :D

Re: Flow-Torq II + 502/415 = ?
 

Well more stuff...
Went out today with my new Mirage Plus 29P and found the limit to the HP of the 502. Never made it to 4600 and slowed down. So much for that well had fun experimenting
Can hit the rev limiter in a hurry with the 25P so I guess a 26 or 27 is in order. Anybody have good luck with 4 blade props?
Needless to say I have a 29P for sale
Here is a link to some fun we had today after the testing. If you live up north where the lakes are still frozen this may warm you up !

Wellllllllll 29P too big. But only slightly boat pulled to 4500. Go figure. :rolleyes: Well selling that one. :(
Was told to try a 4 blade. Any ideas guys?

Re: Flow-Torq II + 502/415 = ?
 

Is your 25 a Mirage plus or the older style?

Re: Flow-Torq II + 502/415 = ?
 

Mirage Plus. Both 25 and 29
Mark what do you think 4 blade ? Smaller pitch 3 ?

Re: Flow-Torq II + 502/415 = ?
 

Give me the speed/rpm for both, and what gear ratio are you running?

Re: Flow-Torq II + 502/415 = ?
 

I assume 1.36 97 502/415/bravo dont know how to tell for sure.
The boat pulls to Rev limit (5000 ) very fast with 25. That is why I figured it would pull such a big jump 29. Rookie :-)
3500=48ish 25p
5000=75

79 was a flop 4400 max at 72ish

Re: Flow-Torq II + 502/415 = ?
 

Get me the serial number of the drive, but the numbers do indicate you most likely have a 1.36. You would pick up a couple of MPH if you change to a 1.5 ratio and then re-prop. Probably a 28" Bravo 1, but you might have to cut the diameter/blade area some. Also your 29 Mirage might work. I bet you had the 29 over-trimmed to get the RPM. BTW, how are you determining your best trim setting? You might want to take a look at this.

Re: Flow-Torq II + 502/415 = ?
 

Yea I did trim up until big slip trying to get it up there.
Bravo 1 as good as some of the big dollar 4 blade props ?
withouth changing gear what would be a logical step to the 4 blade 26? I just placed my 29P up for sale but still own it so far
