Mirage Plus Hole Shot
#11
When trying to get on plane are the Mirage + props slipping or lugging. I am guessing lugging. If they are lugging send the props to BBlades and have them labbed and ventilation holes added. It should get you out of the hole much better, better top speed and raise the RPM to where it needs to be at 5500 RPM.

One encouraged on to the plane by both weight shift and very slow throttle etc. the propellers bite and the acceleration is fantastic all the way up to top speed.
I have sent an email to BBades and are now awaiting their return to work after the holiday weekend.

I would call BBlades and try out a BRAVO 4 blade labbed 24 pitch. should come out of the hole great and get you the top speed like the spineli. That Spineli has a lot of blade surface area.

Many thanks, I am keen to see what BBades come up with.
I tried the Bravo 1 Props. and found that the RPM was exactly correct at 5600 rpm but we lost 3mph. compared to the Spinelli`s turning at 5850 rpm but at 25 % + slip.

I think you will need to go deeper on prop shaft. mine, 2001 29Scarab, twin MPI 383cid 400hp bravo1's, 25p mirage, 7 3/8 deep, 8-9% slip 72-74mph. I tried -3imco and -2imco which made it 4 3/8 and 5 3/8 deep with many props. ran out of time and available props to try. In short of long story, Nothing but a 5 blade would get it on plain at 4 3/8 deep with very much patience. At 5 3/8 deep a Bravo would get on plain but running with 23-26% slip, 3 blade mirage plus was a struggle to keep from blowing out and the % was extremely high. I learned a lot of little things during all this.

Try a set of rev4's. They have the bow lifting characteristics of the mirage plus props on the top end but act like 4wheel drive when fully submerged during take off.

Kalaazar,
Hello, I just saw and read this thread. I'm not sure if we have spoken as to this date.
I looked back in my emails for a note from you and did not find one. However, I'm not sure Kalaazar is the route to find your email. You may have received a email from Brad.
I do have some suggestions and options to help you get to your desired goal. If it is a option for you, please call the office tomorrow and we can discuss the current performance and the options you have.
Sorry for the delay in responding.
Brett
