light on gas, just me on the boat. solid 65 mph,. there was no chop at all... so maybe a little faster in the right water.

but for mags, and loaded not to bad i guess?

Well some more seat time, and differnt waters. some new numbers. (ALL GPS numbers)

medium on gas, 2 people, fresh water, Flat----- 66.8mph
light on gas, 2 people. Salt water, flat -------------67.6 mph
3/4 tank gas, full fresh water, salt water, 2 foot chop with some 3 foot rollers-----68.3 mph..... new best! Tabs at 5-5.5, drives at 7.5

Now, take the props off and switch them. Put the sticks in reverse (now forward) You will pick up more MPH on cruise and max speed.

Some say they dont like the handling but I loved the way the bow rode at 45-50 mph cruise range. Docking will be close to the same as you have an X of close to 7.5 or 8

Yes this is my next plan. I want to try them sprinning in. just want to do that one a weekend when I am not doing alot of docking and stuff in unfamiliar areas. ha.

Yeah, no mater how hard you try, your brain relates forward sticks with forward direction. It is a field day trying to dock that way!

mine actually cruises at 50mph with 9% slip with them out.. 34-3500 rpms.. thought that was pretty good!

mittens what was your max rpms were you turning with those 26 b1's??

We have poker run this Saturday, so I will hopefully get some good #'s from my 25m+ and see where I need to go from there...

The 3blades have done pretty good so far... other than a lil loss of bite on the inside prop when make a decent turn at speed with drives still out a bit. Hoping that a 4 blade would hold better and not kick (roll) out a lil like it does now. Not a hard turn, just a decent turn in the bayou's.

anyone try Rev 4's?? thinking 25p would work well... my 25ol liked it...???

Mine stays hooked up in turns.

at 7.5 trim on drives, 5 on tabs, and WOT I am at 4700-4800 rpms. ar 66-68mph water depending. 66 no matter what.

thanks...

sounds like that's where I will need to start..

Probably will end up testing a 25rev 4 and 26b1.. worse case, I could get 26b1's and could lab later on if needed to..

No issues getting out water? also, what is lowest rpm on a bad day??

edit: just checked your wot range 44-4800.. looks like your closer to your peak hp.. so it would be a toss up on whether lack of extra weight would help me turn more Rs closer to my 5k peak hp.. or simply I might be able to expect the same performance as yours....

The same boats with MAg HOs come with 26 Bravos too. the extra power/ or less weight. helps but you can spin them higher too so yuo might be good.

"If" I can push them higher... I will know after this weekend with the 25's.. will have 4 ppl and just under 3/4 tank and HOT! oh beer too :)

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??

69.1 this weekend. same settings.... but i think the current was helping me a little!

Are either of you running props from Brett? His "Baja Cup" helps a lot a cruise and at wide open throttle. He knows what works and can tweak what you have for a couple more MPH all.around.

Stock as for as I know.. But am getting 9% slip at cruise!
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.

Mine are stock Bavos as far as I know.... I had them repaired when i got the boat, but not cause of a blade problem, just the outer barell was dented where someone dinged it.

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".

Thom

1st post says "mags" :party-smiley-004:

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.

speaking of which, I will be calling Eddie young this a.m., I lost around 800 rpms coincidently when it got hot and after I ran my return lines. Otherwise below 4k, it runs great and gets there easily.

I think I having fuel issues with both return lines T'ed into a 3/8 connection back to the tank and causing lack of fuel at WOT.. otherwise it works great.. I am not that familiar with Fuel Injection/ Fuel pump psi so I will be calling him shortly... I figure I can always test my theory by rerouting 1 return line back to the filter head.

UPDATE: return line not the issue.. Eddie said I probably dropped down a few hundred rpms due to heat and the little extra load I am carrying and it probably fell a few more due to falling under the hp curve in this heat.. Prev owner only used boat at low speed to cruise down river to eat dinner occasionally. hence he only put 12 hours in 2 years on the new motors.

I will try to step down and get some 24 b1's or at least try some 23p m+ to see how I can regain my rpms..

Tried Spinning them in yesterday and saw little to no diffence in speed cruse or WOT. at most .5 mph and that was a fluke. Put them back spinning out now.

Did it carry the bow better or change the RPMS?? Your boat is already running well.. I may try mine spinning IN to see how it handles tomrrw.

Nope rpm / speed was the same. and I tried it the same day back to back same, fuel, 2 people, tested swapped, tested again. swapped back.

What did the bow "feel" like?

How much shyte do you have in your cuddy? LOL

Did not drive it alot really, just testing speeds and looking fro rooter tails. probabyl 5 miles worth. enought o record speeds at differnt rpms, and they where all the same, play with trim at each rpm and then i was done.

I have a fully loaded boat, Genny, AC, Vacuflush, bedding, coffe maker, and tool bag, some plastic plates, towels, and ****. had 1/2-3/4 tank of fuel....

Hey Mittens,

Glad you got the boat. You are correct on being somewhat over propped. The 496 Mags want 4400-4800 rpm. Ideally, 4600 rpm with a moderate load, and fuel. We have 4 blades in every inch of pitch, so a 25" might be better suited for optimal cruise speed as well as top end. We would be glad to discuss your application with you. Please call me at 330-+425-4266.

Thanks,

Thom

3rd time man... WTF? Do you not READ the ****ing threads? Or Just post ****, to see if you can sell a prop? I would be more then happy to call someone and discuss a problem. BUT I DON"T HAVE ONE, at the moment. This is the THIRD time in this one thread you have posted, and not known whats going on. Even when I or someone else responds, you ignore it and then the next time I post, you again try and tell me something that's already stated, and tell me to call and we can work out the problem......

I am at 4700 RPMs, pretty sure that's right in the 4400-4800 range. Not trying to be a dick, but you look like a ass hat not reading the threads and posting the same ****. Let alone PMing me. If you want to sell me something try readying everything, and posting something informational. Like we can KEEP you int he same RPM, but with more speed, or something instead you just post ****.

Well I finally got to run the 33 with props spinning IN!!
It actually rode pretty good. It really got the bow up out the water and actually felt a lil loose. It was just mee with 1/2 fuel and 1-2 chop and hot as dog balls!

It responded to trim better without blowing out and turned 4400 at 63mph but that was with the waves. Docking.. well I swapped the controls, but basically the reverse just didn't pull as much as spinning out.

Not sure if i like the way it felt loose unlike spinning out. Really felt light,but had no weight in boat minus the normal 4-500 extra lbs I normally have. Though it didn't fall over like it does during decent turns like it does with them spinning OUT with it trimmed to neutral.

I assume Bret can lab it and depitch down to a 24- 24.5 pitch to get me some more rpms and get the bow up with them spinning out. Slip is still low 9%

Need to lab them regardless... will have to make a decision to stay in or out.... ?????????

LOL! You've never watched "Days of Thunder" have you? Loose is fast man! C'mon!

"When the rear end's loose, the car's fast. Loose is fast, and on the edge of out of control."

I will have a crew of 10 this Sunday.. thinking of trying it during that run.. hesitate a lil leaving the drives spinning that way and I felt a lil vibration just above idle but was smooth once planed off?? They didn't vibrate OUT.. is that b/c of prop wash from spinning in??

Yeah, the props load differently spinning in and do to different quality of water in that area the props can be running through more aerated water at the just off idle rpm. This can cause a vibration. It's just because their is a load unload scenario going on.
Call me after the weekend if you desire and we can talk about your findings and the in/out pros and cons.

Brett

Sounds good Brett, will definitely have some questions.. boat felt nimble spinning in. Meaning left and right turns were smooth and fluid.

Almost too nimble, but I was the only one in boat and 1/2 fuel. It was pretty hot day and very humid too, not that that affects props other than HP.

Seemed to get on plane with less effort at less than 3k. Anything above would start blowing out.

Would labbing depend on running IN or OUT? With our hulls, would labbing out or in be best??

I did notice a fair amount of rear thrust when IN as i usually launch myself and back off the trailer.
This would probably account for the poor dock manners most ppl mention.

Thanks for the help Brett! I'll try to call you after this week, if we don't get rained out :-(

[ATTACH=CONFIG]506434[/ATTACH][ATTACH=CONFIG]506435[/ATTACH]So I took a pic of the hull as it relates to prop spinning IN.
Looks like its getting a changing direction of water flow as you gain speed.
Makes sense! Expecting 70% chance tmrrw b/c of that crap in gulf.. So test maybe delayed!

Crap! Damn iOS sideways again.. :-(

Our trip to Ship Island got rained out..

to be continued :-)

Just a bump so i can find this thread so its easier to update!
Have some 24p b1's stock spinning IN and a poker run tmrrw with beautiful weather!! Can't wait!! :-)

Poker run went well despite getting trained on. But we had had stopped off at a park to jump in pool and hang out.

Conditions: close to full fuel (oops) trailer gauge and water seem to be a bit different.. water shows more at first. Prob over 3/4 though!!
3 adults and coolers
24p b1 spinning in.

Getting on top, didn't blow out over 3k like m+
Ran up to 4700 easily, but didn't really push it b/c we had boat traffic and constant wakes crossing path. Did cruise to last stop at around 4300-4500 rpms (15 min) running about 60-62 without putting sticks in corner. Wife kept telling me to slow down when she heard the engine tone change as I put in corner :-)

Spinning IN felt good running in chop and flat water, but felt loose when crossing wakes from other boats which I didn't really like. It was quick to turn or felt like quick bow steer. Trimmed out, it wasnt as bad, but larger wakes would fly the bow so I had to use tabs to settle it down.

I will swap them back to out as they felt better and 4 blades should help with blowout in turns.

Overall was heavy on fuel but 4 blades did well, cruise suffered over 25p m+, but I couldn't push them on high end of wot range anyway.

To be cont: will finalize trade on the 25p m+s for the b1s and turn out.. looks like I will be labbing when it gets cold once I have some #s. Spinning IN definitely feels too loose. If I had more power to run 70-80, it would prob be worth it as i would be at front of pack, but not trailing :-) Oh, and Hyd steering would prop help as I am sure some of the loose feeling is cable steering. Not really loose but have a inch or so normal play with cable.

Good deal man. Hope it works

Fiiiinnnnaaalllyyy got to take a ride in the boat. 5 yr old girl with broken leg puts a damper on boatin
85degrees and humid!! Step out in sun and sweat pours humid!!
1/2 fuel and Just me in flat a$$ water.. no breeze.. :-(
24p b1 stock turning out again.

Planed nicely, but i am not hard on sticks so never push them hard to get up even w/ M+'s
3500 @ 45mph
3700 @ 49mph
4000 @ 53mph
48-4900@64mph
Actually P was 4800 and S was 4950.

No blow out in turns, trim had good feel and was able to actually trimout. Definitely more stable than IN.
Using 23.5 p, getting 10.7 slip which leaves some room for improvement.

Odd thing was the S motor was about 2-300 rpms off through most of throttle range. Not sure if I cause but I took helm control out and spun connector on and got it within 1-200. Was never off when i spun IN but I did notice the center wire in the dist cap was not seated and pushed it in the length of a connector, but I was idling back in at that point.

Could that have caused the loss of rpms??

When I changed the throttle position to match, I could hear it hum like it normally does when in sync so i don't think its the gauges as idle up to 2k is still the same????

10.7% slip is about as good as it gets on straight bottom V bottom.
