Over Propped!
 

Well, I got the new 342 wet over the weekend.
I took it easy during the first 6 hours running
between 1500 - 4000 RPM's. Made 2 full speed runs
for about 30 seconds each and I could only get 4500
RPM's with both tabs tucked and the drives trimmed
as high as 7 on the indicators. I had 1/4 tank of fuel with
4 adults. The liquid filled Gaffrig speedo read 68 MPH.
I'm going to swap the 26 Bravo 1's with a pair of 24
labbed race props that the dealer has.
Hoping for 5100 RPM's and 72-73 MPH.
Whats everyone think?

Overpropped...
 

Yep, sounds like too much prop.
You should be turning close to 5000.
The 24's should work out nicely.

I'm assuming you mean the tabs were
up, right ?
24" labs will get you to 5k.

Not sure what your engines are but you sound over propped.

He's got 496HO's(from another thread)

4600-5000rpm.

True but 24's won't get you to 72-73 (even at 5k) :(

For what its worth, I'm running 24 B1s on my 33' Outlaw. Run around 74 (gps) @ 5200 (HP500s). I've tried 28 B1s and they were way too much. I was going to try 26s but Darin wanted a shot at reworking the 24s. I should get them this week.

I think you'll pick up 400 - 600 rpm with the labbed 24s, which should put you in the ballpark.

Better yet how about getting 28's and BLOWERS:) :) :)

I guess I stand corrected.

Are you sure your 24's haven't been re-pitched? Your numbers would suggest a slip of only 6%. :eek:

My 2001 29 has a slip of about 10 - 11% (87mph theory, 77-78 real)

The 342 with ho's should run about 69 or 70 at 5,000
