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.

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.
