SC29

Any ideas? I would like to top out at 70mph. Currently I have some junk Trophy 23's. Running low 60's

Try an old set of 23 cleavers, you have to baby them to get on plane but they will give you the top end you want if the motors have been worked on , they have to be trimmed when you get on plane. good luck ....

I have twin 350s on my 29 with Alpha ones. The props are 4 bladed. Not sure which ones as they came with the boat. I doubt my boat can go 60 but I ride it in open ocean. I've haven't opened it up yet either. 4000RPM is all Ive seen so far. GPS was reading 50MPH

The 29s work best w/ 3 blades, Mirage or Mirage Plus or something similar. Labbed 25s should/will get you around 70.The cleaver style will probably get you the top speed but it will be bear to get on plane and it will not cruise to effectively

I run it yesterday in cool air and hit 62 on GPS @4700rpm. This is with burred up 23's on alpha's and nose cones that need to be reworked a little due to the filler chipping out. I don't think I could spin 25's. My best bet may be some 3 blade labbed 23 mirage Plus's or some 4 blade 21's. Any thoughts on the 4 blades?

I have a 1994 scarab 29 with merc 525sc gen 6 single engine and i run with BBlades lab Bravo 1 26p 4 blade turning at 5050-5100 rpm. I get 70-71 gps any day in summer in cool air probably 1 or 2 mph more.

For my aplication i will love better the 4 blade, I have ran a Mirage Plus 25p 3 blade before and the 3 blade is less faster than a 4 blade in my situation but the 3 blade is the prop that the boat come with when i have buy it so i dont know if the prop have been alredy get repaired or modified i can turn it only at 4850-4900 rpm and 3 mph less faster.
