Well.. boat ran great.. I don't think this thing has loosen up yet..
Hot as dog nuts sat, 4 ppl and geara dn several ice chest :-)
Temps in 90's and humid!!
3400 50mph
3800 @ 55
4200 @ 61mph
4300@ about 62?? All she had at the end of the day and with the storm coming in it was 94 degrees and 95% humidity.
Didnt really play with trim too much as i didn't stay in the corner long.
Thinking I am still in break in period and need to pull some screens off stock intake to help breathe.
When are these things out of break in and start loosing up??? Have about 16 hours on them.
Cruise is goal which was great but seemed heat and humidity was starving engines!
Prev runs :
3 ppl 3/8 fuel 4900 @ 68 at 350 alt in Va 50 degrees
2 ppl 3/8 fuel 4700 at 65 sea level 80. 90+% humidity in lake Pontchartrain.

Mittens.. was just rereading this.. I didn't have good results last time out, but was curious.. tabs at 5 with you best run? What are you at neutral? I would be down a bit at 5?? 3=level.. oh did you try in yet??

Would I lose cruise speed if i labbed with Baja cup? Need help a lil on rpms on top end.. Really goal would be fast cruise at 3800-4k and not putting strain on motors.. Not really worried about wot.

Yes, you'll get better cruise speeds. Of course, the bigger the prop the better mid range but your WOT will suck and probably be 4800 which isnt good either. Tabs should be flat, you wont get bow porpoise and shouldnt need tab, the 342 has good prop depth and carries the bow easy.
I know we've discussed it, but, spinning in is super nice at cruise since you get real good bow lift and several MPH faster. The bow carries much nicer spinning in.

Hello Mittens,
You never said whether you had the 496 Mag or the 496 Mag HO. I assume the 496 Mag. That said, your rpm should be 4400-4800, not 5000-5200. That would suggest a 24-25" pitch 4 blade for the best mid range, handling, and top end. Your boat likes some tail lift, but also wants some bow lift. Please contact me and I will explain what we can do.We build 25" props as well as 24 & 26".

I appritiate the post, but if you read the whole thread, I have figured out my issues, the 26s are working great right now. my rpms are in the range (4700) and i am getting 68mph on GPS with a laoded boat. More seat tiem and more trim was the key
and I have regular Mags. which is pretty damn good. I am going to try spinning in next though. this thread was bumped by NAILIT, as he has the same hull and we have been chating about what works and does not to help him out as well.
